The <strong>FGR</strong><strong>700</strong> <strong>Front</strong> <strong>Fork</strong> is the very essence<br />

of front fork technology and is the<br />

evolutionary result from the FG470, FG570<br />

and FG670. The new, improved front fork<br />

comes fully packed with technical solutions<br />

from <strong>Öhlins</strong> MotoGP technicians.<br />

The new <strong>FGR</strong><strong>700</strong> is a giant leap in the<br />

evolution of high tech front fork systems. It<br />

is pressurised as its predecessors but now<br />

it is equipped with the latest TTX-technology.<br />

Adjust the rebound damping by turning<br />

the screw at the fork bottom. Use<br />

tool 00794-01.<br />

The adjustment range from closed<br />

valve (clockwise) until maximum<br />

Setting Up Your <strong>Front</strong> <strong>Fork</strong>s<br />

Basic Guidelines<br />

- how to set up your <strong>Öhlins</strong> front forks<br />

The front forks are just one part of your<br />

motorcycle and to get it to work properly,<br />

the whole motorcycle has to be set up according<br />

to your vehicle service manual.<br />

1<br />

Put the motorcycle on a work stand and<br />

install the <strong>Öhlins</strong> front fork. Consult your<br />

vehicle service manual.<br />

NOTE!<br />

The lower triple clamp must not be tightened<br />

to more than 12-15 Nm. This is also<br />

important for the steering damper bracket,<br />

when located around the upper front leg.<br />

Too high torque may deform the front fork<br />

leg.<br />

2<br />

Set your initial spring preload, use a 14 mm<br />

socket or wrench, until you get a static<br />

sag of 25-30 mm. Each turn gives 1 mm in<br />

preload, maximum preload is 18 mm.<br />

2<br />

Guidelines -<br />

Setting the Spring Preload<br />

Bike on a stand Bike with rider on<br />

3<br />

The spring preload is very important since<br />

it affects the height of the motorcycle and<br />

the fork angle. Consequently, handling<br />

characteristics can be changed, even<br />

negatively.<br />

Procedure<br />

We recommend you to have an assistant<br />

for this procedure.<br />

1 Put the motorcycle on a stand.<br />

2 Make sure that the shock absorber is fully ex-<br />

tended.<br />

3 Measure the distance from the lower edge of<br />

the rear mud guard or from a point marked by a<br />

piece of tape, immediately above the rear wheel<br />

axle, to the wheel axle. (R1)<br />

4 Make a similar measurement on the front axle, for<br />

example, from the bottom of the upper fork crown<br />

to the front wheel axle. Make sure that the front<br />

fork is fully extended. (F1)<br />

5 Take the same measurements with the rider<br />

and equipment on the motorcycle. It is important<br />

that the rider has a correct riding posture, so that<br />

the weight is balanced on the front and rear wheel<br />

in the same way as when riding. (R2, F2)<br />

4<br />

The measurements should not differ from<br />

the following:<br />

With rider:<br />

Rear: 15-30 mm (R1-R2)<br />

<strong>Front</strong>: 35-50 mm (F1-F2)<br />

1.<br />

Pour <strong>Öhlins</strong> Oil <strong>Front</strong> <strong>Fork</strong> Oil 01311-01<br />

to the top edge of the reservoir. Carefully<br />

continue to fill until the oil level is the same<br />

in the reservoir and the cylinder tube.<br />

2.<br />

Push the gas piston, with the teflon band<br />

and O-ring installed, to the reservoir bottom<br />

without allowing it to be pushed back<br />

over the circlip groove. Make sure that<br />

there is no air between the piston and the<br />

oil. Use tool 00720-02.<br />

Push tool 01765-03 to a stop and check<br />

the oil level according to page 16.<br />

NOTE!<br />

Use <strong>Öhlins</strong> <strong>Front</strong> fork oil 01311-01 only.<br />

Reinstall the top nut assembly to the piston<br />

shaft. Tighten the jam nut to 20 Nm.<br />

Oil Level Adjustment<br />

Compared with conventional type of front<br />

forks, the upside down front forks are very<br />

sensitive to variations in oil level. Therefore,<br />

adjust the oil level with special care.<br />

A change in the fork oil level will not affect<br />

the spring force at the beginning of the fork<br />

travel, but will have a great effect at the<br />

end of the travel.<br />

When the oil level is raised:<br />

The air spring in the later half stage of<br />

travel is stronger, and make the front forks<br />

more progressive.<br />

When the oil level is lowered:<br />

The air spring of the travel is reduced, and<br />

thus the front fork less progressive. The<br />

oil level works most efficient at the end of<br />

the fork travel. Air spring characteristics<br />

shown, is a general card description to understand<br />

the difference when the oil level is<br />

changed.<br />

16<br />

NOTE!<br />

Adjust the oil level in mm according to the<br />

fi gure with the fork leg fully compressed.<br />

For the right oil-level, please see the specifi<br />

cation card.<br />

Air spring characteristics<br />

Air inside the front fork works as a spring.<br />

The graph at the bottom of the page shows<br />

the spring force related to stroke when the<br />

oil level is changed between 140 mm and<br />

200 mm. Standard oil level is 180 mm.<br />

Push to a stop,<br />

use tool 1765-03<br />

Check the oil level


Troubleshooting<br />

Below are a few examples of how to adjust<br />

for the most common road holding problems<br />

in Road Racing driving.<br />

1.<br />

The front wheel “chatters” entering a<br />

corner, the problem goes away, as soon as<br />

you let the brakes off, or when you get on<br />

the power.<br />

This is caused by the fact that the fork is working<br />

too low in the travel and reaches the progressive, hard<br />

part at the end of the travel.<br />

Put on more preload.<br />

Change to a harder spring.<br />

If a lot of stroke remains after riding, drop the oil<br />

level. See oil level chart.<br />

Make sure the front forks have no friction.<br />

Rear ride height is to high, too much rear spring<br />

preload.<br />

Lower the rear end by taking off preload from rear<br />

shock spring.<br />

2.<br />

The front wheel is jumping during the last<br />

part of braking.<br />

If a lot of stroke remains, the oil level is too high.<br />

Lower the oil level.<br />

If the fork is bottoming, put in harder springs and<br />

keep the oil level.<br />

3.<br />

The front end feels unpredictable and unsafe<br />

in the middle of the corner (between<br />

braking and getting on power).<br />

Not enough rebound damping. Put on more<br />

damping.<br />

Too much rebound damping. If it at the same time<br />

feels harsh, take off some rebound damping.<br />

Too much compression damping. Also gives a<br />

harsh feeling. Take off some compression<br />

damping.<br />

17<br />

4.<br />

The front end loses grip coming out of a<br />

corner.<br />

Not enough rebound damping. Put on some more<br />

rebound damping.<br />

Too much preload. Take off some preload.<br />

Rear end is too soft. Put on a harder rear spring.<br />

<strong>Front</strong> end is too high. Lower the front end by<br />

pulling the fork legs through the triple clamps.<br />

As mentioned in the beginning, the whole<br />

bike setup affects the front forks. Try to<br />

understand the feelings and work step by<br />

step.<br />

NOTE!<br />

We advise to change only one thing at a<br />

time and do everything step by step.<br />
