Since it’s inception in 1998, the Rotax Series focus has been on 

the grass roots racer. It is this local weekend warrior that benefi ts from the 

concept of low maintenance, high performance motors. The Rotax Series has 

always been focused on the ability of the driver, and not the depth of the pocketbook. 

The FR125 was fi rst introduced in the United States. Since then we have made the local 

series the main focal point of our program. It is with this focus that the strength and growth 

of the Rotax Series in the United States continues. You, the club racer, can go to your local track, 

enjoy many laps with only minor mechanical maintenance and clean up. Your motor can run 50 hours 

without sending it to the engine shop. This can translate into 2-3 years of racing. You get to race with many 

who have become your friends and share a common bond of friendly competition. Everyone wants to win on 

the track, but in the pits it is everyone working to make sure all have a good time. 

This philosophy works. The proof is the continued growth of the program. The program is designed for a minimum 

of classes, which results in larger fi elds and more track time. 

In 2006 a unique opportunity was presented. Champ Car, looking for a fi rst rung on the ladder, sought out the 

Rotax Max Challenge to be a partner. While our main focus is on the weekend warrior, there are a number of national 

level racers who have chosen to compete in the Rotax series because it truly showcases their driving ability. 

This is the same reason Champ Car offi cials looked to Rotax as its karting affi liate. With this partnership we can 

now offer the young driver, looking to move into the professional ranks, a place to start. In the Rotax series the 

aspiring driver can hone his on track skills and earn the opportunity to showcase his talent in front of professional 

teams at the annual US Rotax Grand Nationals.

being a permanent resident. As a permanent resident, you may travel as much as you like, but your place of residence must 

be the United States and you must keep that residence on a permanent basis. If you leave the United States and stay away for 

more than a year, you risk losing your green card. A link to the website with the above defi nition can be found below.

SCRUTINEERING PROCESS DEFINED 

Note: Those of you familiar with my rules writing style will note the profuse usage of words in this document like ‘should’, 

‘may’, ‘sometimes’, ‘generally’ and similar “soft” words. This should be the fi rst clue that this document is not an offi cial rules 

document, rather an informal explanation for the benefi t of our constituents. 

–Scott G Evans - National Technical Director 

U.S. Rotax Max Challenge 

The scrutineering (technical inspection) process at a kart race can vary widely depending on the organizer but they always 

have the following similarities: Before the event starts - You must get the kart, engine and safety gear inspected and/or recorded 

and during the event - Your kart is subject to some level of scrutineering requirements every time you enter or leave 

the track. 

Before the event, you must have your kart and gear inspected by the event scrutineer(s). This element is also known as 

“pre-tech”. The inspectors will check for safety and eligibility of your kart and gear, possibly recording seal numbers or serial 

numbers depending on the requirements. You should be very familiar with all of the rules before you bring your kart up for 

inspection. Your kart should be well-maintained and clean, bolts and nuts checked for security and weight ballast securely 

mounted per the series’ rules. Numbers should be on the kart, scoring transponder charged and installed in case operation 

or location will be verifi ed. 

Bring your safety gear to pre-tech. Requirements vary with respect to validity of helmets ratings, suits, neck collars, boots 

and gloves. Know the series requirements and make sure any certifi cation tags are visible and in good shape. An inspector 

accepts some - at minimum, moral - liability when knowingly allowing a sub-standard, i.e. expired, piece of safety gear, so 

don’t put him in that position. 

Many times, the inspectors may have some comments about your kart and its condition. Sometimes, the problem is serious 

enough to require your immediate attention before proceeding. Remember that any issues found at this time in this process 

are better than fi nding them later, so try to keep a positive attitude and cooperate with the scrutes. 

The inspectors may “tag” your kart with an identifying band or label to make it apparent that you have passed inspection, 

assigned to a group, or to provide traceability. Sometimes, the process of pre-event scrutineering signifi es your status of being 

under offi cial race control and has implications on chassis, tire and engine usage or other elements of protocol you should be 

aware of. Most of the time, it means - having passed this phase - you are ready to take the track. 

During the event, there is usually a session of “free practice” where you are allowed on track to test and make adjustments. 

As the name implies, you have the freedom from scrutiny here to the extent that weighing in at scales is not normally required, 

your engine will not generally be inspected during this time and the control of tires and fuel is not likely. You do have the obligation 

to keep your kart safe and use the prescribed safety gear, but if you see a scrutineer during free practice it is probably 

for reasons other than inspection. He will be around for that later. 

Nevertheless, many times the inspectors will “cruise” the grid or otherwise monitor activities during free practice. Do not 

despair however, if a grim-looking man is holding his chin and staring at your kart. Most likely he has discovered an anomaly 

on your kart that requires some attention. This is proactive inspection and you should be very glad to see him at this time. 

Again, it is much better to catch issues at this early stage. You may however complain that if your kart passed inspection 

earlier, why the problem now 

Please understand the daunting job it is to inspect the dozens, even hundreds of karts during a pre-event inspection process. 

It is impossible to catch every anomaly and besides, pre-tech is focused on safety and data recording and the scrute may 

want to discuss some other performance-related area or even offer advice on some rule that you need to know. Again, keep 

a positive attitude and cooperate with the scrutes. 

Once qualifying begins, your attention to the scrutineering process will be greater and remain so throughout the event. Once 

you enter the gate to the grid you are under scrutineering control and must submit to their requests to dismount, disassemble 

or otherwise undergo testing to determine your continued eligibility. Most testing done prior to taking the track is non-invasive 

such as quick fuel tests, clutch testing or overall width of your chassis. These pre-element tests are done to ensure fair play 

and avoid post-event exclusions. 

Upon exit from the track, you are generally required to scale yourself and your kart to make sure your minimum weight is 

as prescribed. This usually involves proceeding through a queue with your other competitors while the weight is checked and 

recorded on every kart. In this line, you will likely see another (!) scrutineer, visually making verifi cations while you wait for 

scales. He may ask you to remove your fuel cap or submit to some other test. He may mark or seal key components of your 

engine, requiring this component to remain in use and with all results subject to a possible later inspection of the component. 

But wait, your inspection experience may not yet be done! 

20 presented by

NATIONAL EVENT PROCEDURES SECTION 2 

After you clear the scales, you must be “invited” to leave the scrutineering area. Usually, the top fi nishers of that 

session are invited to stay for post-element inspections, above and beyond what may have already transpired. Make 

sure you know what your status is with the scrutes before you leave. Random choices are sometimes made so be 

sure before you leave. The best person to ask is usually the scale attendant. Almost without exception, leaving the 

controlled area without permission exposes you to penalty. 

If you are lucky enough to be invited to stay, most likely you will be required to dismount the kart, put it up on your 

stand and undergo further testing or measuring with the inspectors. You are required to disassemble anything at 

their request. Refusal usually results in exclusion or disqualifi cation from that element and is generally viewed as an 

admission of guilt. 

So, you ask, if I am disassembling my kart during the event, how do I get it back together Short and sweet, this is 

your responsibility and the scrutes have no liability here. The standard operating procedure is to keep daily inspections 

to an acceptable level without causing undue inconvenience on the competitor. Except in extreme cases, you should 

not expect to have to remove your crankshaft fi rst thing in the morning. You should expect to remove and disassemble 

your carburetor, exhaust, ignition, intake silencers, spark plugs, wheel hubs, brakes amongst others. You may have 

to undergo further fuel or tire testing. It is your responsibility for all disassembly and your readiness to do so speeds 

the process. A simple tool bag carried on your kart stand will suffi ce most of the time in post-tech. Lack of any tools 

causes delays, frustration and congestion. Be prepared. Karts are pretty easy to work on and the scrute will often offer 

his help or advice if you get stuck. 

When the inspections are completed, you will hopefully get the news that all is conforming. You will then be invited to 

leave the controlled area and proceed to the next step of exit, whether it be checking in of your tires or fuel or simply 

exit to the paddock. Either way, you have passed inspections and you should be smiling. 

If the news is something more negative, it means that the scrutes have found something that is not conforming 

to the rules. They will explain to you the concerns they have, show you the rule as required and inform you of their 

intent. Most times, this involves some sort of penalty assessed to you for that particular session. Technical violations 

are usually dealt exclusions or disqualifi cations wherein you would be assessed that penalty in offi cial results. The 

implications for your event success can vary with event structure and depending on the session when the violation 

was discovered. 

You are subject to this inspection process every time you enter and exit the track. Your results may vary, but with 

good preparation and rules knowledge, your scrutineering experience will be fi lled with handshakes and smiling 

congratulations. Without that prep, well, that grim-looking man may have something else to say… 

TECHNICAL NEWSFLASH ENGINE SEAL/CHASSIS PROCEDURE NATIONAL EVENT March 16, 2006 

It has come to our attention that some clarity needs to be applied to the issue of chassis and engine use protocol at 

offi cial Challenge events. The following newsfl ash is designed to provide that clarity. 

Regarding the amount of equipment allowed for any Challenge event, each competitor is limited to one chassis and 

two engines. In initial scrutineering, a tamper-evident designation shall be placed on the chassis and it is only this 

chassis that is permissible for use beginning with practice through the end of the race event. The identifi cation of the 

chassis is recorded and associated with the competitor. 

In case of irreparable chassis damage due to accident, the chassis may be replaced with permission of the event 

scrutineer and/or race director providing the damage is assessed and determined to be indeed irreparable. For local 

Challenge events, the chassis may be replaced with any legal chassis. 

For Grand Regional and Grand National events, the damaged chassis may be replaced ONLY with models of the same 

manufacturer as the originally scrutineered chassis. 

Regarding engines, in initial scrutineering it is required that the USA-origin engine passport be presented for each 

engine desired. The engine(s) must be sealed at the time of presentation and the seal numbers and serial numbers 

of the engines must match the entries on the engine passport. The engine sealing must have been performed by an 

authorized USA sealing agent. Non-United States sourced engines or seals are not to be accepted without prior approval 

from ROTAX National Administration. 

Engine seal numbers are recorded and associated with the competitor in initial scrutineering. 

All engines are to remain sealed for the entirety of the event. Should internal engine service be required, necessitating 

the destruction of the seal, the engine must be submitted to the event scrutineer for any possible technical 

checks that he deems necessary prior to or after breaking of the seal. As a minimum, squish gap conformity must be 

inspected. The scrutineer has the right to be witness to the engine service and is responsible to record the newly-applied 

seal number after service is complete. 

Should any non-conformances be identifi ed during the servicing process, the competitor is subject to exclusion from 

all previous results up to that point in the event. 

It is recommended that if two engines are to be declared for the event, that this declaration occur during the initial 

scrutineering process. It is however permissible for a competitor that has declared a single engine only in initial 

scrutineering to introduce a second engine during the event with notifi cation to the scrutineer. It is never possible to 

introduce a third engine regardless of circumstances. 

It is permissible for multiple competitors to declare a single engine as a backup engine. In this case however, once 

the engine is used by any one of the multiple competitors, it is no longer available to the others. This multiple-use 

presented by 

21

SECTION 2 


notifi cation must be made to the scrutineer at the time of engine declaration. Notifi cation that the backup engine is in use must 

be made to the scrutineer by the competitor that is using it. At that time the engine number will be removed from the other 

competitors’ documentation. If any of the multiple competitors declaring the backup engine is found to be in use of it prior to 

this notifi cation, he is subject to penalty up to and including exclusion from prior results. 

Random verifi cations that engines and chassis matching the scrutineering documents shall be performed during the course 

of the event. Should any non-conformances be identifi ed during this process, the competitor is subject to exclusion from all 

previous results up to that point in the event.

U.S. Rotax Max Challenge 

PARC FERME PROCEDURES 

RULES FOR PARC FERME CHECK IN 

The following is a set of rules to help introduce you to the ins and outs of Parc Ferme, though it may contain some rules within, 

this is merely a summary of such rules an will not be referred to as part of the U.S. Rotax Max Challenge rule book. 

Parc Ferme, loosely translated to English, means closed area, which is exactly what it is. Parc Ferme is a servicing and storage 

area for your offi cial event fuel and tires, with limited access only to approved or invited competitors. Parc Ferme, also 

referred to as a servicing compound, servicing parks, impound area, or assembly/disassembly area, is composed of a fenced 

in area, a building, or combination of both which will store and protect the integrity of the competitor’s fuel and tires. Once 

introduced to Parc Ferme, a competitor’s fuel and tires may not leave the designated area. Should a competitor’s fuel or tires 

leave the area they would not be able to reintroduce said equipment. It will save you money and a fair amount of aggravation 

if you commit this to memory and ask yourself each time you head toward the exit of Parc Ferme “Did I return everything I 

need to Parc Ferme” 

Parc Ferme preparation starts at home. To make you life simpler, make sure you have a spare fuel jug and tank for your kart. 

The fuel and tank will be stored within Parc Ferme for the duration of the weekend. You will need a separate practice fuel jug 

and tank. 

LABEL EVERYTING!!!!! This cannot be stressed enough. Label everything you introduce to Parc Ferme. Your fuel jugs, fuel 

tank, wheels, mixing containers and rain tires. Label your gear permanently and as large as possible. the offi cials and Parc 

Ferme attendants are there to house and secure your race equipment, but it is ultimately the competitor’s responsibility to 

make sure his/her equipment is labeled properly. Never leave anything unattended in Parc Ferme. Though your day may be 

hectic and chaotic and you think you have more important things to be doing, always wait until you watch the Parc Ferme 

attendant place your equipment back in its proper place. Each competitor has a specifi c storage space that will not change 

during the course of the weekend. When you fi rst check in your equipment, watch where the attendants place your tires and 

fuel. It is the attendant’s job to store your equipment, but it is your responsibility to make sure that it is labeled and accessible 

for each segment of the race weekend. Again, LABEL EVERYTHING!!!! 

A day will be designated as the equipment introduction day. This day is usually the day of practice, before qualifying starts. 

The times for this process will be offi cially posted on the schedule for the race weekend. Don not fret, checking in is simple. 

Bring an empty fuel jug, tickets for tires, oil and fuel, and ALL of the rain tires you wish to use for the entire race event, to the 

offi cials at the Parc Ferme check-in entrance. You also must have your credentials for the corresponding driver you wish to 

check-in. At all times, no access will be granted to anyone who does not have proper identifi cation and equipment will only 

be issued through a visual inspection of credentials by attendants. With credentials, tickets, empty inspected fuel jug and rain 

tires for the weekend in hand, you will head to Parc Ferme to procure your oil, fuel, and slick tires. The attendants will log in 

your fuel, oil, and tires and store it. As per the Rotax Kart Challenge rule book, your rain tires must be in wrappers or have the 

nubs to indicate they are new. Wrapped rain tires will then be logged in with the attendants and stored. You have no successfully 

fulfi lled all of your Parc Ferme requirements. Mounting of tires and mixing of fuel is performed at you’re discretion and is 

not part of the scheduled time constraints of Parc Ferme. Parc Ferme is open from scheduled opening time to the designated 

deadline and the attendants and offi cials will help log in any competitor in nay class during this window. It would be to your 

advantage to take care of it early in the day so that it is done and you are not standing in line with the rest of the competitors 

that put it off until the last minute. 

This is just a summary of what is required for your Parc Ferme check-in and hopefully answers all of your questions about 

how the check-in process works. If you have nay further questions or concerns, offi cials at the track will gladly help. 

PARC FERME RULES FOR RACE EVENTS 

Now that you have labeled, checked-in and stored your equipment it is time to retrieve your gear and for racing. The following 

rules allow you to properly enter and exit Parc Ferme during the race event. Again a simple disclaimer, this is a summarize 

guideline. It is the competitor’s responsibility to acquire any additional documents made available to Rotax participants. These 

additional documents may contain supplements to the rules and clarifi cations. 

Kart Presentation to Parc Ferme Entrance 

• Both the driver and mechanic must have proper credentials corresponding with the kart number being introduced. 

• Fuel Lines must be drained. If reporting with the tank on the kart the tank must be completely empty. 

- Parc Ferme Offi cials will inspect driver/mechanic credentials, kart, and toll boxes prior to admittance to assembly area. No 

22 presented by

PRACTICE 

BRIEFING 


fl uids or loose weights are permitted within the confi nes of Parc Ferme, with the exception of beverages which 

we make you prove by drinking in out witness. Any allowed beverages MUST be consumed or disposed of prior to 

release from Parc Ferme to pre-grid. 

After inspection, you will be directed to an area to place your kart in order to assemble for racing. With credentials in 

hand for visual inspection by attendants, you will head for the issuing table. The attendant will inspect your credentials 

and retrieve the equipment you request. Once you have assembled and fueled your kart, return your fuel jug to the 

issuing table for storage. Next, wait until an offi cial release you to the pre-grid. During this time you should make sure 

that you have everything you will need to compete in the on track race segment. Once released from the assembly 

area of the Parc Ferme to the pre-grid, there is no way to exit the area and return. If a driver or mechanic leaves the 

pre-grid area, he/she will not be allowed to return. No additional parts or tools may be introduced to the pre-grid area, 

so before you leave the assembly area of Parc Ferme, make sure you have everything you need. 

Having completed the on track segment, crossed the scales, and fulfi lled any post race technical inspection you 

will immediately proceed to the disassembly area. In the disassembly area you will remove tires and fuel tank and 

return them to the Return Table. DO not just drop your equipment and walk away, stay with your tires and fuel until 

the attendant picks them up to place them in the storage area. You should also check your tires and fuel tank to make 

sure that all are still properly marked before handing them over to the attendant. If a mark or marks are missing the 

attendant will remark or label equipment under your supervision. With all competition tires and fuel properly stored 

with Parc Ferme attendants, you may now return to your paddock and get ready for the next segment. This procedure 

will repeat itself for each race session. 

Practice sessions are not under Parc Ferme requirements and therefore no fuel or tires will be issue for use during 

morning warm ups on race days. 

At Scrutineering a sticker was placed on the steering fairing of your kart. This sticker indicates your class and practice 

group. Practice times for your group are listed on the offi cial schedule for the day. 

You may only practice with your designated group. If for any reason you feel a change to another group is needed 

this request must be made to the Grid Marshall, the Grid Marshall is the only person that may grant a change to your 

practice group. 

While on the track, all fl ags will be obeyed, the same as under race conditions. No driver may cut the track or drive in 

the reverse direction of normal traffi c fl ow unless directed by a track offi cial. Failure to comply will mean forfeiture of 

this practice session and possible forfeiture of additional practice sessions as dictated by Event Offi cials. 

Hot pitting will only be allowed during practice sessions specifi cally designated as hot pit practice sessions. If the 

driver exits the track for any reason his practice session is considered to be fi nished. A driver may pull into a safe area 

to inspect his kart but no mechanic is allowed. If a mechanic touches the kart for any reason the driver’s session is 

done. 

The last practice session will be considered a Hot Pit session and a Hot Pit area will be designated. All hot pit practice 

sessions are under the same controls as offi cial qualifying sessions. Make sure the driver and mechanic have all parts 

and tools needed before entering the Hot Pit area. Once the mechanic has entered this area he may not leave until 

he considers his driver fi nished. The mechanic may not leave and re-enter the Hot Pit area nor may tools or parts be 

entered by other persons. A driver may pull in and with the help of his mechanic make changes to his kart or engine. 

All parts taken into the hot pit area, removed from the engine or kart are subject to inspection and/or impound at any 

time. 

Once qualifying has started no additional practice sessions will be offered. There may be a morning warm up prior 

to each day’s offi cial sessions. These are conducted under practice rules. Offi cial tires and fuel from Parc Ferme may 

not be used for these sessions. If you do not have other tires and rims you will not be allowed to participate. If you do 

not have an extra fuel tank check with Parc Ferme Director for the procedure you will need to follow allowing you to 

use your fuel tank for morning warm-ups and then re-enter the fuel tank into Parc Ferme. 

The last offi cial practice session will be used to determine qualifying groups. Once this practice session has completed 

you should remove your practice sticker because morning warm up groups will be determined by the days 

scheduled events. See the daily schedule to determine your morning warm up time if it is offered. 

A) Defi nition: The Entrants’ and Drivers’ Briefi ng is a meeting organised by the Race DIrector for all Mechanics and 

Drivers entered in the Event. 

B) Aim of the Briefi ng: to remind Entrants and Drivers of the specifi c points of the Supplementary Regulations concerning 

the organisation of the Event; to remind them of the safety notions, either general, or specifi c to the circuit 

used; to give any clarifi cation concerning the interpretation of the Regulations. 

C) The time of the Briefi ng is mentioned in the program of the Event. The time is considered as that of the beginning 

of the Briefi ng and the entrance door and access to the Briefi ng will be closed. The meeting shall always be held before 

Qualifying Practice or the fi rst Qualifying Heat. Extra meetings may be organised if this is deemed necessary. 

D) The presence of all concerned Mechanics and Drivers is mandatory throughout the Briefi ng under pain of a sanction 

or even of a possible exclusion from the Event. Two Attendance Sheets shall be signed, one by Drivers and the 

presented by 

23

SECTION 2 


other by Mechanics. 

E) Before they can be allowed to continue the event, a mandatory fi ne of US $50.00 which must be paid to the Event Organizer 

(USRMC) hosting the event via the Race Offi cials will be infl icted on any Mechanic and Driver who do not attend the Briefi ng. 

QUALIFYING-LAST CHANCE RACE 

Following the last offi cial practice qualifying groups will be set. Classes will be divided into equal sizes and the slowest qualifying 

group will compete fi rst during each classes qualifying period. 

Following qualifying drivers will be listed per qualifying times with the fastest at the top. Starting grids for heat races will be 

determined based on class size; 

For classes with 36 or less the starting grid will be set for each of the 3 heats based on qualifying times. The Starting grid for 

each of the 3 heats will be the same. 

For classes with 37-72 entries, 4 grids will be set with a maximum of 18 in each grid. From the qualifying order the grids will 

be set using the qualifying positions as outlined below; 

Grid A B C D

The points are totaled for each competitor, the lowest 28 in points will transfer directly to the Pre-Final. Those fi nishing in 

point total positions 29-64 will compete in a 20km Last Chance Race with the top 6 fi nishers transferring to the Pre-Final in 

positions 29-34 based on their fi nishing positions in the LCR. Those fi nishing with points totals from 65th and lower will have 

completed their competition. 

In the event of ties for points qualifying times will be the tie breaker. In the case where qualifying times are equal best fi nishes 

will then become the tie breaker. 

STARTING PROCEDURE 

Each grid/class will be lined up in order on the grid. IF A COMPETITOR DOES NOT ARRIVE IN TIME OR DROPS OUT, THIS SPOT 

MUST BE LEFT OPEN ON THE FORMATION LAP UNTIL THE FORMATION FLAGS HAVE BEEN PASSED. Once past the formation 

fl ags open spots should be fi lled by each competitor in the line moving up. Each group will leave the grid for 2 warm up laps. 

The fi rst lap is to done at 75% of race speed. Once each competitor crosses the start fi nish line the group should form up. If 

a pace car is used it will pickup the grid at some point passed the start fi nish line on the formation lap. At approximately the 

3/4 point of the formation lap yellow fl ags (formation fl ags) on each side of the track will indicate the end of formation line. If 

anything occurs causing the competitor to fall behind the fi eld, competitor has until they reach the formation fl ags to regain 

their position. If not into their starting position by the formation fl ags competitor should move into a position corresponding to 

24 presented by


their location in the fi eld at the point of the formation fl ags. At no time may a competitor use a short cut to catch up to 

the fi eld. Using a short cut will result in a time penalty equal to 1 lap. 

The fi eld will proceed at a speed dictated by a pace vehicle if one is on track. If no pace vehicle is used the speed 

should be slightly less than half speed, the leaders should use their Tachometer to determine this with 6,000 RPM 

being the ideal speed. 

If a Driver stops for any reason during the Formation Lap, he will not be allowed to try and start again before he has 

been passed by the whole fi eld. He shall start again from the back of the formation. Should he try to start ahead of 

the fi eld in the hope that the leading drivers overtake him, he would be shown the black fl ag and be excluded from 

that race. 

Driver who is delayed will have the possibility of regaining his grid position only if this manoeuvre does not impede 

other Drivers and in all cases before having reached the End of Formation Cones on the formation lap which will is 

indicated by 2 cones with Yellow Flags on each side of the track and location shown by the Race Director at the 

Briefi ng. 

The difference in the 2 paragraphs above are 1. “If a driver stops” i.e. chain falls off and driver stops to put chain 

back on. 2. “Driver is delayed” driver(s) spin or go off track during the hot lap. 

If he (Race Director) considers that a Driver has been immobilized as a result of another Driver’s mistake, the Race 

Director may stop the formation lap and start again the starting procedure on the basis of the original grid or allow the 

impeded Driver to regain his position. 

In the case of repeated false starts or incidents during the Formation Lap(s), the Race Offi cials may issue penalties to 

offending drivers that will be added to drivers total time at the end of the race. This penalty may be a time or position 

penalty. 

Any attempts to jump the start or delay it shall be sanctioned. Penalty(s) will be assessed by time upon the fi nish of 

the Heat/Race. 

As soon as the start has been given, racing conditions are applied and, irrelevant of the position of a kart on the track, 

it is forbidden to give it any assistance, except for moving it to a safe location. This restriction does not apply to the 

Mini Max class. Race Offi cials may help a Mini Max driver move his/her vehicle into a position to allow safe entrance 

back onto the racing surface. 

ACCELERATION ON STARTS 

Cones will be placed on each side of the track at a point approximately 25 meters before the start fi nish line. Cones 

will also be placed in the center of the track separating the two starting lines. This is the acceleration point for the 

competitors. It is the responsibility of the Pole position to set the pace and the responsibility of the off pole to remain 

with the pole driver without lagging or jumping. Both front row drivers should accelerate at the same time with drivers 

in rows following the front row accelerating at the same time. The green fl ag will be displayed by the Head Flag Man at 

some point after the acceleration cones. If the Race Director or the Head Flag Man calls for an aborted start the Head 

Flag Man will turn away from the starting fi eld and walk away from the track, at which time all competitors should 

raise their hand indicating a waved off start. All Corner Marshals will immediately display yellow fl ags. At this time 

the group needs to re form into the starting grid. Any driver who did not get into their starting position by the formation 

cones must remain where they are at, they may not attempt to move into their original starting position. If there 

has been an aborted start one more opportunity will be given for a correct start. If the start is aborted a second time 

offending drivers will be penalized on the fi nish of the race. Drivers found to be ahead of scheduled starting position 

will be penalized the number of positions gained plus 3. This does not apply if the line advances to fi ll a missing spot 

once passed the formation cones on the formation lap. 

No competitor may break formation until the green fl ag is displayed by the Head Flag Man, and the last cone placed 

in the center of the track is passed. A move out of formation prior to the Green Flag being given or passing the last 

cone in the center of the track will result in a minimum 15 second penalty for each offending driver(s). This penalty 

will be assessed at the end of the race. 

DRIVING INFRACTIONS 

HEATS 

A rolled black fl ag with an accompanying driver’s number on a display board will be a warning for a driving infraction. 

Penalties for driving infractions may be assessed with or without warning. Penalties will be assessed as a time penalty 

or a position penalty and applied at the end of the race. There is no maximum as to the amount of time a competitor 

may be assessed for a penalty. 

A waved Black Flag indicates the driver needs to exit the track, in a safe manner, the next time the driver comes to 

the track exit. The kart number will also be displayed at the start/fi nish line on a display board. Failure to exit the track, 

in a safe manner, may result in additional penalties. 

Each class will compete in 3 heats based on the qualifying positions. Heats will be 8-12 laps determined by Race Offi 

cials, based on the length of the track. Starting grids and points assignments for fi nishing positions will be assigned 

as outlined below. (Three heats will be for classes with 80 competitors or less. For classes with 81 or more competitors 

the number of heats will change based on the heat system used per CIK rules.

SECTION 2 


Each competitor will be given points based on their fi nishing position in each of the heats. Points are assigned as follows; 

1st 0 6th 6 11th 11 16th 16 

2nd 2 7th 7 12th 12 17th 17 

3rd 3 8th 8 13th 13 18th 18

5th 5 10th 10 15th 15 

PRE-FINALS 

FINALS 

The points are totaled for each competitor; the lowest 28 in points will transfer directly to the Pre-Final. Those fi nishing in 

point total positions 29-64 will compete in a 20km Last Chance Race with the top 6 fi nishers transferring to the Pre-Final in 

positions 29-34 based on their fi nishing positions in the LCR. Those fi nishing with points totals from 65th and lower will have 

completed their competition. 

In the event of ties for points qualifying times will be the tie breaker. In the case where qualifying times are equal best fi nishes 

will then become the tie breaker. 

Pre-Finals will be 20km in length as specifi ed in the CIK Specifi c Prescriptions. This will apply to all classes except Mini Max 

which will be 15km. The starting line up for the Pre-Final will be as outlined in the section on Heats above. The fi nishing order 

of the Pr-Final will determine the starting order of the Final. 

The starting order of the Final will be set as the fi nishing order of the Pre-Final. The length will be 30km for all classes except 

Mini Max which will be 20km. The winner of the Final will be awarded the title of U.S. Rotax Max Challenge Champion for the 

specifi c class for the year. 

All fi nishes of each qualifying, heat, LCR, Pre-Final and Final are unoffi cial until post race technical inspections are completed. 

RED FLAGS AND RESTARTS 

PROTESTS: 

When Red Flags are displayed by Corner Marshals and Race Offi cials all competitors should slow down and raise their hand 

high indicating they have seen the Red Flag signals. Competitors should proceed to a point on the track indicated during the 

Driver’s Briefi ng and wait for instructions from Race Offi cials. 

If a heat/race is red fl agged due to apparent driver injury, the driver requiring medical attention will not be allowed to re-start. 

Race offi cials may mandate a driver be evaluated by medical personnel. This will apply to “complete and single fi le restarts” 

If a race is red fl agged because of unsafe track conditions all drivers directly involved in the incident requiring the red fl ag 

will start at the back of the grid on the restart (single fi le restart only). Only drivers that were listed as crossing the start fi nish 

line on the lap preceding the red fl ag will be allowed to restart. Drivers retiring prior to the lap on which the red fl ag occurred 

will not be allowed to reenter the race. 

If a repair period is designated all competitors will move to a controlled area designated by the Head of Tech for the event. 

The repair period will be 30 minutes and the Parc Ferme Director and Tech Director and/or Parc Ferme Director will oversee 

the area. Mechanics will be allowed to bring in tools and parts as outlined by the Tech Director and/or Parc Ferme Director 

during this period. 

The restart line up will be determined by scoring offi cials as the last completed lap. If less than 2 laps have been completed 

the race will have been considered, never started. A complete new start will be given using the original starting lineup. A race 

will be considered complete if 75% of the scheduled laps have been completed. 

The defi nition of a completed lap is when all karts have crossed the start fi nish line with the exception of karts no longer 

running or karts delayed to the start fi nish line due to on track incidents. The determination of 2 laps being completed will be 

accomplished by race offi cials. 

Protest forms will be available at a designated location during the event. This location will be identifi ed at the drivers meeting. 

All protest forms will be submitted to a designated person. All protests will be accompanied by a $50.00 Protest Fee, cash or 

check only. If the protest is upheld the $50.00 will be returned. If the protest is denied the $50.00 protest fee will be not be returned. 

Decisions on protests will be made within 30 minutes of presentation to Race Director. All parties involved in the protest 

will be called to the Race Director and at the conclusion of the current race on the track will be informed of the decision.

17 NUMBER OF KARTS ALLOWED ON THE TRACK 

A) The number of karts allowed on the track is limited to 34 for fi nal phase races, 36 for Qualifying Practice and the Qualifying 

Heats and 51 for Non-Qualifying Practice. 

18 CODE OF DRIVING CONDUCT ON KART CIRCUITS 

18.1 OBSERVANCE OF SIGNALS 

The instructions detailed in Article 2.15 of the General Prescriptions and in Article 2.3 of the Circuit Regulations (Part II) are 

deemed to be part of this Code of Driving Conduct. All Drivers must be thoroughly acquainted with them. 

18.2 OVERTAKING 

A) During a race, a kart alone on the track may use the full width of the said track. However, as soon as it is caught up by a 

kart which is either temporarily or constantly faster, the Driver is not allowed to swing from one side to the other or make a 

move sideways in order to prevent a legal overtaking manoeuvre when the other Competitor is already by his side. He shall 

give the other kart the right of way in order to allow for passing. 

B) If the Driver who has been caught does not seem to notice that another Driver wants to overtake him, the flag Marshal(s) 

will give a warning by waving the blue flag to indicate that another Competitor wants to overtake. Any Driver who does not 

take notice of the blue flag may be penalised by the Stewards. 

Systematic or repeated offences may result in the exclusion of the offender from the race. 

C) Curves, as well as the approach and exit zones thereof, may be negotiated by the Drivers in any way they wish, within 

the limits of the track. Overtaking, according to the circumstances, may be done either on the right or on the left. However, 

manoeuvres liable to hinder other Drivers such as premature or dangerous changes of direction, more than one change of 

direction, deliberate crowding of karts towards the inside or the outside of the curve or any other dangerous change of direction, 

are strictly prohibited and shall be penalised, according to the importance and repetition of the offences, by penalties 

ranging from a fi ne to the exclusion from the race. The repetition of dangerous driving, even involuntary, may result in the 

exclusion from the race. 

D) Any obstructive manoeuvre carried out by one or several Drivers, either having common interests or not, is prohibited. The 

persistent driving abreast of several karts, as well as fan-shaped arrangement, is authorised only if there is not another kart 

trying to overtake. Otherwise the blue flag will be waved. 

E) The penalty infl icted for ignoring the blue flag will also be applied to the Drivers who obstruct part of the track and shall 

be more severe in the case of systematic obstruction, thus ranging from a fi ne to the exclusion from the race. The same 

penalty shall be applied to Drivers who swing from one side of the track to the other in order to prevent other Competitors 

from overtaking. 

F) The repetition of serious mistakes or the appearance of a lack of control over the kart (such as leaving the track) may entail 

the exclusion of the Drivers concerned. 

G) The race track alone shall be used by the Drivers during the race. 

H) Contacts / collisions (during the race, decelaration lap included): sanctions may be imposed on a Driver who pushes 

another Driver. 

18.3 STOPPING OF A KART DURING THE RACE 

A) The Driver of any kart leaving the race shall signal this intention in good time and is responsible for ensuring that the 

manoeuvre is carried out safely and as near as possible to the point of exit. 

B) Should a Driver be compelled to stop his/her kart, either involuntarily or for any other reason, the kart shall be moved off 

the track as soon as possible so that its presence does not constitute a danger or prevent the normal running of the race. If 

the Driver is not able to move the kart out of the potentially dangerous position, it is the duty of the Marshals or other offi cials 

to help. 

C) Any replenishment carried out on the track itself is prohibited, and will entail immediate exclusion. 

D) Apart from the Driver - and, in exceptional cases, the competent offi cials - nobody is allowed to touch a stopped kart under 

penalty of its exclusion from the race. 

E) Pushing a kart along the track or pushing it across the finishing line is not allowed, and will entail immediate exclusion.

SECTION 3 


GRAND FINALS 

F) Any kart abandoned on the circuit by its Driver, even temporarily, shall be considered as withdrawn from the race. A kart 

left temporarily by its Driver whilst a race is suspended will not be considered abandoned. 

18.4 ENTRANCE TO THE PITS (OR REPAIRS AREA OR SERVICING PARKS) 

A) The so-called «deceleration zone» is a part of the pits area. 

B) During the practice sessions and the race, access to the pits or to the Repairs Area is allowed only through the deceleration 

zone. The penalty for a breach of this rule shall be exclusion from the race. 

C) Any Driver intending to leave the track or to enter the pits or the Servicing Park or the Repairs Area shall signal his intention 

in good time and make sure that it is safe to do so. 

D) Except in cases of Force Majeure (accepted as such by the Stewards of the meeting), the crossing, in any direction, of the 

line separating the deceleration zone and the track is prohibited. 

E) Except in cases of Force Majeure (accepted as such by the Stewards of the meeting), any line painted on the track at the 

pit exit or the Repairs Area for the purpose of separating karts leaving the pits or the Repair Area from those on the track must 

not be crossed by any part of a kart leaving the pits. 

19 RUNNING OF THE EVENT 

A) The Event will comprise Non-Qualifying Practice, Qualifying Practice, Qualifying Heats, a Second Chance Heat and a fi nal 

phase as a minimum. 

a) Non-qualifying Practice: 

The time schedule of the Event must provide for Non-Qualifying Practice for each category. 

They are reserved for those Drivers having passed the Sporting Checks and Scrutineering. The Drivers shall be divided 

into two series for odd and even numbers. Sessions will be alternated every thirty minutes. 

The use of transponders is mandatory as from the beginning of the Non-Qualifying Practice. 

b) Qualifying Practice: 

Drivers who have passed Scrutineering are divided into equal series if possible, by drawing lots in the presence of at 

least one Steward. One 15-minute session per series is provided for. Each series will comprise a maximum number of 

36 Drivers. During each session, Drivers will take the start when they choose. Any Driver having crossed the line drawn 

at the exit of the start area will be considered as being a starter and his lap time will be taken into account, whatever the 

circumstances. Any lap fully covered is timed. The time retained is that of the best lap covered during the two sessions. 

Any ties will be decided by the 2nd best time set by each Driver, and so on in the case of further ties. 

The fi nal classifi cation of Qualifying Practice will be drawn up as follows: 

• If there is only one series: the grid will be drawn up in the order of the fastest time achieved by each Driver. 

• If there are two series and if the fastest time achieved in the slower series is not more than 101% of the fastest time 

achieved in the faster series: the classifi cation will be determined by the order of the fastest times achieved by each 

Driver. 

• If there are two series and if the fastest time achieved in the slower series is more than 101% of the fastest time 

achieved in the faster series: 1st place goes to the fastest time of the 1st series (fastest time overall), 2nd place to 

the fastest time of the 2nd series, 3rd place to the 2nd fastest of the 1st series, 4th place to the 2nd fastest time of 

the 2nd series, 5th place to the 3rd fastest time of the 1st series, and so on. 

• and so on according to the same principle if there are further series. 

If no time is taken into account for a Driver, he/she will take the start at the end of the Grid. If several Drivers are in that situation, 

their starting position will be decided by drawing lots. Pushers are not allowed to help Drivers once they have crossed 

the line drawn at the exit of the start area. 

If a Driver stops in the Repairs Area or in the Servicing Park, it will be fi nal. He/she shall not be allowed to start again. 

c) Qualifying Heats: 

Case A: 36 starters or less - Three Qualifying Heats will be run with all the Drivers. The starting grids of each of the three 

Heats will be established on the basis of the results of Qualifying Practice. 

Case B: 37 to 72 entered Drivers - At the end of Qualifying Practice, Drivers will be separated into groups for the Qualifying 

Heats. The number of Drivers per group will be 18 maximum. Each group must compete versus all the other groups. 

• As an example, in the case of a separation of Drivers into 4 groups, the Driver classifi ed 1st in Qualifying Practice will 

be in group A, the 2nd in group B, the 3rd in group C, the 4th in group D, the 5th in group A, the 6th in group B, the 

7th in group C, the 8th in group D, and so on. 

• Each of the four above-mentioned groups will compete against the other groups, i.e.: A versus B, A versus C, A versus 

D, B versus C, B versus D and C versus D, namely a total of six Qualifying Heats. Each Qualifying Heat will have a 

40 presented by

GRAND FINALS 


distance of approximately 10 or 15 km according to the age bracket of Drivers (Juniors/Seniors). 

• For the Qualifying Heats, points will be awarded as follows: 0 point to the 1st, 2 points to the 2nd, 3 points to the 3rd 

and so on according to an increasing progression of one point per place. If a Driver does not take the start in a Qualifying 

Heat, he will receive a number of points equal to the number of participants of groups A and B plus 1. 

• If a Driver has been black-fl agged or excluded, he will receive a number of points equal to the number of participants 

of groups A and B plus 2. 

• Any Driver who has not covered all the laps scheduled, even if he has not fi nished the Qualifying Heat, will be classifi 

ed according to the number of laps he has actually completed. 

• At the end of the Qualifying Heats, the fi rst 28 classifi ed Drivers will be qualifi ed for the fi nal phase. Possible ties between 

two or several Drivers will be settled according to their classifi cation in Qualifying Practice. If the Drivers have 

been divided into 5 groups or more, the fi rst 34 classifi ed Drivers will be qualifi ed for the fi nal phase. 

d) Second Chance Heat: 

• Only the fi rst 34 non-qualifi ed Drivers may participate in the Second Chance Heat of approximately 10 or 15 km (according 

to the age bracket of the Drivers - Juniors/Seniors). 

• Starting positions will be determined according to the total number of points obtained in the Qualifying Heats. 

• The fi rst 6 fi nishers will be qualifi ed for the fi nal phase. 

e) Final Phase: 

34 Drivers will compete in the fi nal phase according to the following format: Pre-Final and Final. 

20 STARTING GRIDS 

* Pre-Final: Starting positions according to the number of points received in the Qualifying Heats. The fi rst six Drivers 

qualifi ed in the Second Chance Heat will have the last positions respecting the fi nishing order of the Second Chance 

Heat. Drivers who did not take the start of the pre-fi nal or were excluded from it will not be authorised to participate 

in the fi nal. 

* Finale: Starting positions determined by the classifi cation of the Pre-Final. 

The distance of the Pre-Final and Final, from the starting signal to the chequered fl ag, will be equal to the minimum 

number of full laps necessary for reaching the respective distances, which are 15 km for the Prefi nal and and 25 km 

for the Final for the Junior Class and 20 km for Prefi nal and 30 km for Final for all other classes. The chequered fl ag 

will be shown to the leading kart when it crosses the fi nishing line («the Line») at the end of the lap during which that 

distance is reached. The Line consists in a single line across the track. The fi nal classifi cation of the Event will be the 

classifi cation of the Final. 

f) During the Second Chance Heat and the fi nal phase, any Driver about to be overtaken by the race leader(s) or who 

has been overtaken for any reason whatsoever will be shown the blue and red (double diagonal) fl ag with his number. 

He shall return to the scales in the Parc Fermé and will be classifi ed according to the number of laps that he has 

actually completed. 

A) At the end of the fi nal Qualifying Practice session, the list of qualifi ed Drivers as well as the starting grids will be offi cially 

published. 

B) Only these Drivers will be allowed to take the start of the Qualifying Heats and/or of the race(s) of the fi nal phase. 

C) Any Entrant whose kart(s) is (are) unable to take the start for any reason whatsoever or who has good reasons to believe 

that his kart(s) will not be ready to take the start must inform the Offi cial in charge of the Assembly Area, who will advise the 

Clerk of the Course as soon as he has the opportunity. 

D) The grid shall be made up of two lines of karts. For the heats, the grid shall be arranged in the order of the best lap times 

set during qualifying practice. Should one or several Drivers achieve the same time, the tie will be settled on the basis of their 

second best time, and so on. 

The grid for the pre-fi nal shall be based on points accumulated in the heats. Starting position in the fi nal will be determined 

by the fi nishing positions of the pre-fi nal. 

E) The pole position Driver of each grid will have the choice in the pole position (on the left or right side of the track), providing 

that he advises the Clerk of the Course as soon as he reaches the Assembly Area. This choice will only modify the fi rst row, 

to the exclusion of the others. Failing this, the pole position Driver of each grid will take the start of the race from the grid 

position designated as such in the Supplementary Regulations of the Event.

B) The start will be of the «rolling» type, The regulations for “Rolling start for karts with clutches and without gearbox” of the 

CIK-FIA general regulations apply. the grid being constituted of two lines of karts. 

C) To give the start, the Clerk of the Course shall be placed on a platform located at least 5 metres from the trackside and 

behind a permanent protecting barrier (Article 7.7.1C of the Circuits Regulations, Part 1). 

D) A Yellow Line shall be painted 25 m ahead of the Start Line. It is forbidden to accelerate before having crossed that line. For 

rolling starts, this Yellow Line will also be materialised by a row of soft cones (1 cone on each side of the track and 4 cones 

placed on the centre line of the track). 

E) As soon as the Clerk of the Course indicates with the green fl ag that the karts may take the start, the Drivers are «at the 

orders of the Clerk of the Course» and may no longer receive any outside help. Any Driver who has not placed himself at the 

orders of the Clerk of the Course in time with his kart in working order will be allowed to leave the Assembly Area only at the 

orders of the Clerk of the Course or of the offi cer in charge of the Assembly Area. 

F) Karts will cover one warm up lap and one formation lap (total 2 paps) before the start may be given. It is forbidden to 

overtake another Driver under pain of a penalty infl icted by the Stewards (10 seconds or exclusion from the Heat). 

G) If a Driver stops for any reason during the Formation Lap, he will not be allowed to try and start again before he has been 

passed by the whole fi eld. He shall start again from the back of the formation. Should he try to start ahead of the fi eld in the 

hope that the leading drivers overtake him, he would be shown the black fl ag and be excluded from that race. 

H) Driver who is delayed will have the possibility of regaining his grid position only if this manoeuvre does not impede other 

Drivers and in all cases before having reached the Red Line which will be materialised on the track and indicated by the Clerk 

of the Course at the Briefi ng. 

I) If he (the Clerk of the Course) considers that a Driver has been immobilized as a result of another Driver’s mistake, the Clerk 

of the Course may stop the formation lap and start again the starting procedure on the basis of the original grid or allow the 

impeded Driver to regain his position. 

J) At the end of the formation lap, drivers will go at slow speed towards the start line assembled in two lines of karts. During 

the approach stage, the red light will be on. No karts may accelerate before the red lights have been switched off. Karts must 

maintain their position until the start signal is given. If the Clerk of the Course he is satisfi ed with the formation he will give the 

start by switching off the red lights. If he is not satisfi ed with the procedure, he will switch on the orange light, which means 

that an extra formation lap must be covered. Should the engine of a driver stop during formation lap, an offi cial or mechanic 

nominated to carry out that task may restart him as soon as he/she has been passed by the entire fi eld. He may then rejoin 

at the back of the formation and must not try to regain his grid position. If the kart cannot be started, then it must be removed 

from the track to a place of safety. Similarly should a driver fall behind the entire fi eld without stopping, he must remain at 

the rear for the start and must not attempt to regain his position. 

K) In the case of repeated false starts or incidents during the Formation Lap(s), the Clerk of the Course, acting as a Judge of 

Fact, may stop the starting procedure by means of the red fl ag and inform the Stewards, who will be entitled to infl ict on the 

offending Drivers a penalty according to Article 2.24 of the General Prescriptions. A new procedure will begin either immediately 

or within 30 minutes, according to the circumstances. The starting grid will be the same as for the initial procedure. All 

the Drivers present in the starting area or in repair area before the procedure was stopped will be allowed to take the start 

of the new Formation Lap. 

L) Any attempts to jump the start or delay it shall be sanctioned according to Article 2.24 of the General Prescriptions. 

M) As soon as the start has been given, racing conditions are applied and, irrelevant of the position of a kart on the track, it 

is forbidden to give it any assistance, except for parking it to a safe location.

GRAND FINALS 


N) The Stewards may use any video or electronic system likely to help them to take a decision. The Stewards’ decisions may 

supersede those taken by Judges of Fact. Any infringement to the provisions of the Code or of these Sporting Regulations 

relating to the starting procedure may entail the exclusion of the kart and of the Driver concerned from the Event. 

22 STOPPING A RACE 

A) Should it become necessary to stop the race or practice because the circuit is blocked by an accident or because weather 

or other conditions make it dangerous to continue, the Clerk of the Course shall order a red fl ag to be shown on the Line. 

Simultaneously, red fl ags will be shown at Marshals’ posts provided with these fl ags. The decision to stop the race or practice 

may be taken only by the Clerk of the Course (or, if he had to leave, by his deputy). If the signal to stop racing is given: 

a) during practice, all karts shall immediately reduce speed and go back slowly to the «Finish» Servicing Park, and all 

karts abandoned on the track shall be removed; 

b) during the Qualifying Heats: all karts will immediately reduce their speed and go to the «Finish» Servicing Park 

entrance, considering that: 

• the classifi cation of the race will be the classifi cation at the end of the lap prior to that during which the signal to 

stop was given, 

• karts or rescue vehicles may be on the track, 

• the circuit may be totally blocked because of an accident, 

• the weather conditions may have made it impossible to drive at high speed on the circuit. 

The procedure to be followed varies according to the number of laps completed by the race leader before the signal 

to stop was given: 

• less than 75% of the distance scheduled for the race (rounded up to the nearest higher whole number of laps). If 

the race can be restarted, Article 2.22 will apply. 

• 75% or more of the distance scheduled for the race (rounded up to the nearest higher whole number of laps). The 

karts will be directly led to the Parc Fermé, and the race will be considered as having stopped when the leading 

kart crossed the Line at the end of the lap prior to that during which the signal to stop was given; 

c) during a race of the fi nal phase, all karts must immediately reduce speed and go to the entrance to the «Finish» 

Servicing Park, considering that: 

• the classifi cation of the race will be the classifi cation at the end of the lap prior to that during which the signal to 

stop the race was given, 

• karts or rescue vehicles may be on the track, 

• the circuit may be totally blocked because of an accident, 

• the weather conditions may have made it impossible to drive on the circuit at racing speed. 

B) The procedure to be followed varies according to the number of laps completed by the race leader before the signal to 

stop the race was given: 

Case A: less than 2 laps. No points will be awarded. If the race can be restarted, Article 2.22 Case A will apply. 

Case B: more than 2 laps but less than 75% of the distance scheduled for the race (rounded up to the nearest whole 

number of laps). If the race can be restarted, Article 2.22 Case B will apply. Should this not be possible, half the points 

will be awarded. 

Case C: 75% or more of the race distance (rounded up to the nearest whole higher number of laps). The karts shall be 

sent directly to the Parc Fermé and the race will be deemed to have fi nished when the leading kart crossed the Line at 

the end of the lap prior to that during which the race was stopped. Full points will be awarded. 

23 RESTARTING A RACE 

A) Working on karts will be allowed only in the Servicing Park; it will even also be allowed to introduce spare equipment (only 

the equipment identifi ed in the case of chassis and/or engines) in the Servicing Park. Re fuelling will be allowed. 

Case A: If less than 2 laps have been covered, a new start will be given within 30 minutes after presentation of the red 

fl ag (in the conditions provided for under Article 2.19 F). The length of the new race will be the full original race distance. 

The original start will be deemed null and void. 

The starting grid will be the same as for the original race. 

Those Drivers having crossed the Finish Line at the end of the lap prior to that during which the race was stopped 

and those who were in the Repairs Area when the red fl ag was shown will be eligible to take the restart, either in their 

original kart or in their reserve kart. Unoccupied places on the grid shall remain vacant.

SECTION 3 


GRAND FINALS 

Case B: If more than 2 laps have been covered, a new start will be given within 30 minutes after presentation of the 

red fl ag (in the conditions provided for under Article 2.19). The length of the new race will be equal to the difference 

beween the scheduled number of laps and the number of laps covered. The Drivers who have crossed the Finish Line 

at the end of the lap prior to that on which the race was stopped and those who were in the Repairs Area (except in a 

fi nal phase race) when the red fl ag was shown will be allowed to take the new start, either in their original kart, or with 

a reserve kart. The fi rst kart and the reserve kart are allowed in the «Start» Servicing Park. 

Grid positions will be determined by the fi nishing order at the end of the lap before the one on which the race was 

stopped. 

The result of a race which has been stopped and restarted is the addition of the times of the stopped race and those 

of the race held after the restart. 

24 NEUTRALISATION OF A QUALIFYING HEAT OR RACE 

A) The Clerk of the Course or the Race Director may decideto neutralise a Qualifying Heat or a Race. This procedurewill be 

used only if the Track is obstructed, or if the Drivers or Offi cials are in immediate physical danger, but thecircumstances are 

not suffi cient to justify stopping theQualifying Heat or Race. 

B) When the order is given to neutralise the QualifyingHeat or Race, all observers’ posts will display waved yellow fl ags and a 

“SLOW” board (yellow board with the word“SLOW” written in black), which shall be maintained untilthe neutralisation is over. 

Flashing orange lights will beswitched on at the Line. 

C) All the competing karts must then line up behindthe leading kart, and overtaking is strictly forbidden. 

Overtaking will be permitted only if a kart slows downbecause of a serious problem. 

D) During the neutralisation laps, the leading kart willdictate the pace, at a moderate speed, and all the otherkarts must 

remain in as tight a formation as possible. 

E) The karts may enter the repair zone during the neutralisation,but they may rejoin the track only when authorisedto do so 

by a marshal. A kart rejoining the track shall proceed at an moderate speed until it reaches the end ofthe line of karts behind 

the leading kart. 

F) When the Race Director or the Clerk of the Course decides to end the neutralisation, he will have the fl ashing orange lights 

switched off; this will be the signal to theDrivers that the Race is to resume next time the Line is crossed. In the last neutralisation 

lap, the “SLOW” boardswill be maintained and the yellow fl ags will be shown immobile. 

G) At that moment, the leading kart will continue to set the pace, at a moderate speed. The Race Director or the Clerk of the 

Course will signal the resumption of the Race by means of a waved green fl ag at the Line. Overtaking will remain prohibited 

until the karts have crossed the Line at the end of the neutralization of the Qualifying Heat or Race. On approaching the Line, 

where a green fl ag will be waved by the Race Director or the Clerk of the Course, the Drivers may accelerate only after crossing 

the yellow line preceding the Line. The yellow fl ags and the “SLOW”boards at the observers’ posts will then be withdrawn 

and replaced with waved green fl ags. These fl ags will be displayed for a maximum of one lap. 

H) Each lap completed during the neutralization will be counted as a racing lap. 

I) If the race fi nishes during the neutralization, the karts will take the chequered fl ag as usual, without being allowed to 

overtake. Overtaking will be permitted only if a kart slows down because of a serious problem. 

25 SCALE / WEIGHING PROCEDURE 

A) The scale of the day will be located in “Servicing Park”. This scale is the ONLY one which will be offi cially used and 

counted. The scale will be available from Thursday morning. 

B) After Qualifying Practice, the Qualifying Heats and the races of the fi nal phase, each kart crossing the Line will be weighed. 

If the kart is unable to reach the Weighing Area by its own means it will be placed under the exclusive control of the Marshals, 

who will take it there or have it taken there, and the Driver shall report to the Weighing Area as soon as he returns to the pits 

so that his weight may be established. 

C) At the end of Qualifying Practice the Driver and his kart will be weighed simultaneously then separately. Should for reasons 

of “Force Majeure” the Driver be unable to go to the scales at the end of a Qualifying Heat or of a race of the fi nal phase, his 

kart would be weighed on its own and the Driver’s weight registered after Qualifying Practice would be added to that of the 

kart. 

D) No solid, liquid or gaseous matter or substance of any nature whatsoever may be added to a kart, placed on it or removed 

from it before Weighing (except by a Scrutineer within the framework of his offi cial duties).

it has been authorized by these Offi cials. 

F) A kart or a Driver are not allowed to leave the Weighing Area without the authorization of the Scrutineer. 

G) Any infringement to these provisions relating to the Weighing or karts may entail the exclusion of the Driver and kart 

concerned. 

H) The Organizer shall place the scales under a shelter at the entrance to the “Finish” Servicing Park and must provide for 

suffi cient personnel to ensure the placing of the kart on the scales. Mechanics will be kept away from the karts until the 

Weighing Procedure of their karts is over. 

I) If the weight of a Driver and of his kart is under that specifi ed in the Technical Regulations, the result will be communicated 

in writing to the Entrant, and the kart and its Driver will be excluded from Qualifying Practice, the Qualifying Heat or the race 

concerned. 

J) The Organiser must provide for certifi ed weights for the calibration of the scales. 

K) Drinking water from a clear plastic bottle is allowed in servicing park, before weighing, however any driver pouring water 

over head and race overall will be penalized with 1 (one) additional KG on the weight of kart and driver (i.e., junior 145 + 1 

= 146) 

26 FINISH 

A) The signal indicating the end of the race shall be given on the Line as soon as the leading kart has covered the full race 

distance. 

B) Should, for any reason other than under Article 2.21 A, the signal indicating the end of the race be given before the leading 

kart completes the scheduled number of laps, the race will be deemed to have fi nished when the leading kart last crossed 

the Line before the signal was given. Should the signal indicating the end of the race be delayed for any reason, the race will 

be deemed to have fi nished when, under normal circumstances, the end of the race would have been decided if there had 

been no delay. 

C) After having received the signal indicating the end of the race, all karts shall directly go to the Parc Fermé, without stopping 

and without any help (except that of Marshals if necessary).

9. ENGINES 

At RMC, RMCGF and IRMCE races, engines which are confi rm to the following technical specifi cation only, are legal to be 

used. 

For national RMC’s, engines are allowed to be used only, which have been checked and sealed by the 

NATIONAL RMC’S ONLY 

ROTAX Authorised Distributor of this territory or one of the Service Centers appointed by the Authorised 

Distributor. For national RMC’s the ROTAX Authorised Distributor of this territory has to publish the lists of Service Centers 

which are legal to check and seal engines. 

For IRMCE all ROTAX Authorised Distributors and their Service Centers only are allowed to check and seal engines. ROTAX will 

publish a list of Autorized Distributors and their Service Centers which are legal to check and seal engines. For RMCGF ROTAX 

only is allowed to check and seal engines. 

By sealing an engine the ROTAX Authorised Distributors and their Service Centers take over the responsibility for the conformity 

of the engine with according to the valid Technical Specifi cation. Also a brand new engine must be checked according to the 

Technical Specifi cation before sealing. 

The engines have to be sealed with specifi c ROTAX engine seals (black anodised aluminium seal with ROTAX -logo and a 6 digit 

presented by 

49

SECTION 4 



serial no. see attached picture). 

Further legal seals are, for 125 MAX 

class, black anodised aluminium seals 

3 1 

with JAG-logo and 6 digit serial no. and 

for 125 Junior MAX class, red anodised 

aluminium seals with JAG-logo and 6 

digit serial no. 

2 

By means of the steel cable the engine 

must be sealed on one Allen screw (1) of 

the intake fl ange, on one stud screw (2) 

of cylinder and one Allen screw (3) of the cylinder head cover (see attached pictures). 

At evey new sealing of an engine the authority (ROTAX Authorised Distributor or their Service Centers) that checks and seales 

an engine is responsible for following indications at the Engine Identity Card which belongs to the owner of the engine. 

_ Serial no. of the engine 

_ Serial no. of the engine seal 

_ Stamp and signature of the company to be able to detect at scrutineering which authority has checked and sealed the 

engine. 

At scrutineering the driver has to present 

• The engine(s) with the undamaged engine seal(s) 

• The Engine Identity Card(s), showing the matching engine serial no.(s), the matching 

engine seal no.(s) and the stamp(s) and signature(s) of the authority(ies) that has 

(have) checked and sealed the engine(s). 

The ROTAX Authorised Distributor organizing a national RMC 

NATIONAL RMC’S ONLY 

may appoint before every RMC race a neutral Service Center 

which will be the only one allowed to re-seal an engine between scrutineering an the 

fi nal in the case of an engine failure. 

During an IRMCE ROTAX Authorised Distributors and their Service Centes are not allowed 

to re-seal an engine between scrutineering and the fi nal. 

The sealing of engines helps to reduce the times for scrutineering at races as during 

the race event just the accessories (carburettor, exhaust, radiator…..) must be 

checked. 

Of course scrutineers can request to open and re-check an engine according to the Technical Specifi cation, before or after a 

race or in case of a protest. If an engine seal has been broken (for which reason ever), the engine has to be checked completely 

according to the Technical Specifi cation and must then be re-sealed by an ROTAX Authorised Distributor or one of its Service 

Centers. 

Genuine ROTAX components only, that are specifi cally designed and supplied for the 125 Junior MAX-, the 125 MAX- and the 

125 MAX DD2 engine are legal, unless otherwise specifi ed. 

Neither the engine nor any of its ancillaries may be modifi ed in any way. Modifi ed is defi ned as any change in form, content or

If it’s not being waved, don’t drive 

off the track, someone else did. 

If you get the black flag, pull into

Stop! Right Now! Pull off to the

Someone faster is behind, let them 

by and you’ll make them happy 

When waving, it means one more

You’re all done. Slow down and
