QUALITY<br />

MADE IN JAPAN<br />

There is no other form of transport that gives a<br />

sense of speed and of rounding corners dynamically<br />

than does the motorcycle. But this also<br />

means that the motorcycle rider must always<br />

reckon with a spill, whether on the race track<br />

or an ordinary country road or in the town. It<br />

is therefore essential for all riders to take suitable<br />

measures to protect against injury in a<br />

crash, whereby the central and undoubtedly<br />

most important element is the helmet.<br />

Introduction<br />

At SHOEI highly specialized employees develop<br />

and produce helmets on the basis of the very<br />

latest technology, and to a large part this is done<br />

by hand. Thanks to decades of experience and<br />

our passion for helmet technology, millions of<br />

passionate motorcycle riders place their trust in<br />

the SHOEI brand.<br />

With its <strong>com</strong>pany headquarters in Japan and<br />

further locations in Europe and the USA, SHOEI<br />

reaches its customers in almost 40 countries<br />

around the globe and thus belongs to one of<br />

the leading brands in the international helmet<br />

segment.<br />

OUR PHILOSOPHY<br />

Three factors – A first class helmet<br />

Of course, the main function of a helmet is to<br />

protect the head of the rider in the event of an<br />

impact. However, we have defined the requirements<br />

concerning SHOEI helmets in a more<br />

<strong>com</strong>prehensive way. Consequently the basis of<br />

SAFETY<br />

COMFORT PASSION<br />

our product philosophy is 3 core aspects:<br />

the safety of the impact protection, a maximum<br />

degree of <strong>com</strong>fort in any situation and the passion<br />

for motorcycling have been the basis for the<br />

development of all SHOEI helmets since 1959.


THE SHOEI<br />

SAFETY CONCEPT<br />

In addition to the basic safety properties that ensure protection in the event of an impact, there<br />

are also the <strong>com</strong>fort aspects that characterise an outstanding helmet. A <strong>com</strong>fortable helmet<br />

makes a decisive contribution to relieving the load on the rider and helps his concentration – an<br />

important constituent part of the SHOEI safety concept.<br />

Passive safety – active safety<br />

Ensuring its helmets <strong>com</strong>ply with the various<br />

standards worldwide for passive safety takes top<br />

priority at SHOEI. Our strict quality assurance<br />

ensures that this applies at all times and for<br />

all SHOEI helmets. But our products have also<br />

made a number of contributions to active safety.<br />

For example, the aerodynamics, the <strong>com</strong>fortable<br />

all help the rider to concentrate on the one<br />

important thing: driving safely.<br />

WHAT MAKES A SHOEI<br />

HELMET STAND OUT<br />

Of all types of helmets, a motorcycle helmet is the one that has to meet the toughest requirements<br />

concerning its protective function. Its strong outer shell and its broad impact protection<br />

distinguish it fundamentally from other types of helmets.<br />

The visor<br />

The visor protects the rider against wind, dirt, insects and UV radiation, but<br />

at all times it must also guarantee clear vision without any optical distortion.<br />

The helmet shell<br />

The helmet shell absorbs the impact energy in the event of a fall and distributes<br />

it over the largest possible area.<br />

The EPS liner (inner shell)<br />

The energy that is passed on by the helmet shell is taken up by the shockabsorbing<br />

inner shell and ensures a maximum degree of safety. The helmet<br />

inner shell consists of light, shock-absorbing polystyrene and is pressed<br />

together in the event of an impact.<br />

The inner padding<br />

The inner padding consists of high-quality polyurethane foam of various<br />

levels of hardness with covers of pleasant padding materials and ensures a<br />

perfect hold and pleasant seating.<br />

The chin strap<br />

The task of the chin strap is to hold the helmet firmly on the head. This<br />

is done by using a chin strap whose tensile strength and extensibility are<br />

matched especially to this function. The chin strap is firmly attached to the<br />

helmet shell by means of metal rivets.<br />

Ventilation<br />

The SHOEI helmet<br />

The constituent parts<br />

and their functions<br />

The SHOEI ventilation system directs the wind from the speed of travel into<br />

the helmet and guides warm and damp air to the outside. Ventilation is one<br />

of the elementary and important innovations in the equipment of our more<br />

recent models. The perfect placing and shaping of the inlets, outlets and channels<br />

is the basis of optimum ventilation and requires a very special know-how.<br />

Technical Book<br />

PASSIVE SAFETY<br />

The impact protection for the head is used to provide passive safety and is, as explained<br />

above, a major constituent part of the SHOEI safety concept. The performance of a helmet with<br />

regard to passive safety is measured on the basis of various international safety standards.<br />

Thanks to many years of know-how and our <strong>com</strong>mitment to quality assurance, the performance<br />

properties of all SHOEI helmets are clearly above the requirements of these standards.<br />

The ECE R22/05 standard<br />

A number of safety standards have established<br />

themselves worldwide and they differ markedly<br />

from one another concerning their criteria and<br />

test scenarios, in accordance with the requirements<br />

in the various countries. The ECE R22/05<br />

Directive applies in all the countries of the ECE<br />

(Economic Commission for Europe) and those<br />

countries that have associated themselves with<br />

this standard. Helmets that do not <strong>com</strong>ply with<br />

this Directive may not be sold in the relevant<br />

countries of the ECE – with few exceptions.<br />

The ECE R22/05 standard tests among other<br />

things the impact damping, the chin strap, the rolloff<br />

behaviour, the structure and the resistance.<br />

The inner shell of a SHOEI helmet<br />

In accordance with its high level of quality, each<br />

SHOEI helmet that is offered for sale in Europe is<br />

given a shock-absorbing double inner shell with<br />

a special shaping. The <strong>com</strong>bination of the various<br />

grades of expanded EPS provides an effective<br />

damping of shocks and impacts and at the<br />

same time for a low HIC value. The upper part<br />

Two criteria are tested in the impact damping<br />

test. On the one hand, the permissible value<br />

for the maximum acceleration is measured in g<br />

(Peak G) and on the other hand the HIC (Head<br />

Injury Criterion), hence the risk of injury for the<br />

head. The HIC represents the total amount of<br />

energy that acts on the head and is calculated<br />

from the impact speed and the length of time<br />

that the force acts. The maximum permitted<br />

values of 275 g and 2400 for the HIC are<br />

handled very strictly in the ECE countries. The<br />

special properties of the outer shell, the high<br />

shock-absorbing ability of the inner shell and<br />

absolute quality assurance ensure that SHOEI<br />

meets these stipulations at all times and shows<br />

the very best results.<br />

of the helmet inner shell is generally softer than<br />

the outer edge. The relatively hard edge of the<br />

inner shell increases the damping effect in the<br />

event of a crash and provides a low HIC value.<br />

The technology has been patented and is regarded<br />

as the technical property of SHOEI.

ACTIVE SAFETY<br />

As opposed to “passive safety” that is ensured by <strong>com</strong>pliance with the various country-specific<br />

safety standards, “active safety” means an improvement in wearing <strong>com</strong>fort to allow the rider<br />

to devote his full concentration to driving.<br />

Product properties such as improved inner padding for optimum seating of the helmet, the<br />

lowest possible weight to reduce stress on the neck muscles, an effective ventilation system for<br />

temperature regulation and a reduction of wind noises primarily serve the safety of the rider.<br />

This underscores the importance of the continuous further development of SHOEI helmets in<br />

the area of <strong>com</strong>fort technology.<br />

The inner padding<br />

The interaction of wearing <strong>com</strong>fort and proper fit<br />

The material and the shape of the inner padding are decisive for<br />

the wearing <strong>com</strong>fort and proper fit of the helmet. The wearing<br />

<strong>com</strong>fort covers the effect of the material properties on the skin<br />

of the rider. The fit defines how well the helmet sits on the head<br />

and stays in place and is especially noticeable at high speeds.<br />

In the past these two criteria often worked against one another.<br />

Very thick, soft padding provided good wearing <strong>com</strong>fort, but it<br />

did not hold well at high speeds and led to wobbling.<br />

SHOEI rethought the structure and function of the inner padding<br />

and developed a new concept. The inner shell of the helmet was<br />

shaped to the head, and thus, thinner padding can be used.<br />

This in turn is produced in a <strong>com</strong>plicated process either from<br />

multiple layers of polyurethane foam of different hardnesses or<br />

else is cut three-dimensionally from a block so as to ensure<br />

optimum hold together with high wearing <strong>com</strong>fort.<br />

Optimisation of the cover materials<br />

The development of new high-performance fabrics allows<br />

the function of the padding with regard to taking up sweat<br />

to be optimised to the extent that we can talk of a “summer<br />

covering”. This is used in the first instance in motocross<br />

and in road racing sport where the amount of physical exertion<br />

and hence the production of sweat is extremely high.<br />

Savings in weight and aerodynamics<br />

Improved safety through lighter helmets<br />

Three factors are crucial for the weight of the<br />

helmet as perceived by the rider. The actual<br />

weight that is felt by wearing the helmet, the felt<br />

weight and the dynamic weight which is pro-<br />

The helmet shell that has been optimised for weight<br />

The heaviest part of a helmet is the helmet shell<br />

and this is of special importance when making a<br />

light helmet. Since the shell is also the part of the<br />

helmet that is the most stressed in the event of an<br />

impact, the requirements concerning the manufacture<br />

of a light helmet shell are correspondingly<br />

high. Through its extensive experience in the processing<br />

of fibre <strong>com</strong>pound materials, SHOEI has<br />

succeeded in developing the extremely resistant<br />

and light AIM and AIM+ helmet shells.<br />

1. Shaping process with fibre-reinforced layer<br />

matrix. Generally, an outer shell that is made<br />

of fibreglass (FRP) is given its shape by a<br />

heat-setting plastic. The SHOEI outer shell<br />

owes its ideal function to the integration of organic<br />

fibres and of three-dimensional shaping<br />

in a layered structure. This produces a helmet<br />

outer shell that is characterised by high<br />

strength for a very low weight as <strong>com</strong>pared to<br />

shells that are produced in a conventional way.<br />

2. The <strong>com</strong>pound structure. The AIM shell<br />

consists of various layers of reinforcing organic<br />

fibres and glass fibres. Compared to an outer<br />

shell that is only made of glass fibres, the AIM<br />

outer shell is both lighter and more elastic for the<br />

same strength, and the AIM+ outer shell is even<br />

lighter due to the additional use of special fibres.<br />

SHOEI AIM stands for “Advanced Integrated Matrix” and is made up of three main features:<br />

unsaturated polyester resin, a so-called heatsetting<br />

plastic, is used for the AIM outer shell.<br />

This resin acquires the desired strength and<br />

elasticity during the heat hardening process.<br />

This synthetic resin is also extremely resistant to<br />

corrosion for good measure.<br />

Technical Book<br />

The advantage of the AIM outer shell over shells that are hardened all the way through.<br />

The AIM outer shell from SHOEI<br />

primarily offers in addition to its<br />

enormous weight advantages the<br />

best possible impact protection<br />

as well. Through the interaction<br />

of the strength and the elasticity<br />

of the various materials, the AIM<br />

outer shell has been designed in<br />

such a way that the effect of an<br />

impact is absorbed as well as is<br />

possible and is distributed over<br />

the entire shell and inner shell.<br />

Helmet<br />

shell<br />

Thus the outer shell and the inner shell may show damage from deformation after an impact, but the head of the rider<br />

is given the maximum amount of protection as a result. Heavy, hard helmet shells do not have this ability and direct<br />

the energy from an impact without any reduction into the inside of the helmet. In many cases the shell may be undamaged<br />

but it was not possible to avoid head injuries. This applies in particular to helmets that were primarily designed<br />

to prevent penetration by sharp objects.<br />

Improving the aerodynamics<br />

The stress applied to the neck muscles when<br />

riding a motorcycle <strong>com</strong>es not only from the<br />

weight of the helmet itself but also, above all,<br />

from the air resistance. For that reason improving<br />

the aerodynamics is an important factor in<br />

preventing the onset of tiredness. The SHOEI<br />

product development section regularly makes<br />

tests in its own wind tunnel to design helmets<br />

with optimum aerodynamic properties.<br />

Ventilation<br />

Direction of acceleration in<br />

a crash<br />

Head<br />

Back in the early 1980s SHOEI developed a<br />

ventilation system that passed air through holes<br />

in the helmet shell without affecting the stability<br />

of the outer shell. The idea that good ventilation<br />

is crucial for the safety of a helmet caused<br />

a fundamental change in the design of motorcycle<br />

helmets. This once again makes it clear<br />

how important the safety concepts and a spirit<br />

of innovation are at SHOEI. The investment in<br />

a wind tunnel of our own allows us to carry out<br />

intensive studies in the development of effective<br />

and high-performance ventilation systems.<br />

SHOEI has developed a dual EPS liner (inner<br />

shell) whose air system allows an optimum exchange<br />

of warm, used air and in<strong>com</strong>ing cold<br />

fresh air.<br />

The dual EPS liner, a<br />

Warm air is effectively<br />

directed to the outside<br />

by the two layers and<br />

this considerably<br />

improves the ventilation<br />

performance.<br />

The effect of the ventilation<br />

during tests in the<br />

wind tunnel is shown in<br />

colour. The helmet with<br />

the visor is exposed to<br />

a wind speed of 100<br />

km/h. The drop in temperature<br />

is measured<br />

after 5 minutes.


The SHOEI visor system<br />

The visor protects the rider against wind, dirt<br />

and insects. In addition to full face helmets,<br />

many open helmets and half helmets are also<br />

provided with a visor. All SHOEI visors are made<br />

of polycarbonate. Most of them are produced by<br />

the so-called injection moulding process. This<br />

guarantees clear and distortion-free vision. Furthermore,<br />

the visor protects against small stones<br />

and absorbs 99% of the UV radiation, its coating<br />

prevents scratches and lets water roll off more<br />

easily in beads. Except the Hornet-DS model all<br />

visors are provided with SHOEI’s own Q.R.B.P.<br />

The Pinlock® anti-fogging system<br />

Our visors are equipped with the Pinlock® antifogging<br />

system that ensures a clear shield under<br />

virtually all weather conditions. The doubleshield<br />

technology has an insulating effect and<br />

prevents fogging of the visor.<br />

Noise exposure<br />

A high level of noise imposes unnecessary stress<br />

on the rider and disturbs his concentration. There<br />

are two ways to reduce noise in the helmet<br />

through suitable design. On the one hand, wind<br />

noise can be reduced by optimising the aerodynamics.<br />

On the other hand, the acoustic damping<br />

properties of the helmet can be optimised by<br />

suitable design of the helmet shell and the padding.<br />

The decisive factor for a <strong>com</strong>fortable and<br />

quiet helmet is the balanced utilization of these<br />

two approaches. Reducing the noise through a<br />

thicker helmet shell, doing without ventilation or<br />

using padding that is too tight may reduce the<br />

amount of noise experienced, but this is achieved<br />

at the expense of safety and <strong>com</strong>fort and<br />

hence is not an option for SHOEI.<br />

AND DEVELOPMENT<br />

All SHOEI helmets are developed from the three points of view of safety, <strong>com</strong>fort and passion.<br />

Information gained from all over the world goes into the development.<br />

Safety, design and passion<br />

All SHOEI helmets are developed from the three<br />

points of view of safety, <strong>com</strong>fort and passion.<br />

Product development takes customer wishes,<br />

the state of the market and new trends into<br />

consideration. Although safety and functionality<br />

Tests in the wind tunnel<br />

More than 20 years ago SHOEI was the first<br />

maker to recognise the importance of aerodynamics<br />

for a helmet. In the meantime SHOEI<br />

has a wind tunnel of its own that is an<br />

indispensable constituent part of product<br />

development. In addition to the effects of air<br />

resistance and the various forces applied,<br />

tests are constantly made of the performance<br />

of the ventilation and how noise is produced.<br />

always play the dominant role, the design<br />

aspect is never neglected. This special <strong>com</strong>bination<br />

of perfect functionality and unique<br />

design is testimony to the same passion that<br />

motorcycle riders all over the world experience.


Test drives<br />

Intensive test drives are done in addition to verify<br />

the results of the wind tunnel testing. For<br />

example, the various forms of air flow for different<br />

types of motorcycles or <strong>com</strong>fort on long<br />

stretches are investigated and taken into consideration<br />

when developing a helmet design.<br />

Racing service<br />

Nowhere are the requirements placed on a<br />

helmet more extreme than in professional racing<br />

sport. The development of SHOEI sports<br />

helmets is decisively supported by our factory<br />

riders in the MotoGP and other international<br />

The SHOEI helmet<br />

classes. Among other things, the ventilation system<br />

and the quick-change visor system were<br />

developed first for racing sport. Today every rider<br />

technologies.<br />

PRODUCTION &<br />

QUALITY ASSURANCE<br />

For all the energy and passion that are invested in the development of a product, in the<br />

last resort the quality in series production must <strong>com</strong>ply with the specifications from the<br />

development section. The following explains on the basis of the manufacturing process<br />

what it is that makes up the unique quality of SHOEI helmets.<br />

Production of the helmet shell<br />

SHOEI exclusively uses fibre-reinforced plastics that offer the<br />

best properties for the manufacture of a helmet shell. Thanks<br />

to having many years of experience and highly specialised employees,<br />

SHOEI is in a position to produce helmet shells that<br />

are extremely strong and yet light. Each helmet shell is marked<br />

personally by the employee who is responsible for it and thus<br />

puts his name on the line for the quality of this example.<br />

Laser cutting<br />

Here the helmet is given its final shape. All the protrusions that<br />

area created in manufacture are cut off. The openings for the<br />

visor and ventilation are burnt into the helmet shell with a laser.<br />

Finally the helmet is checked to ensure that it has the correct<br />

material thickness and weight.<br />

Painting<br />

Even though many production steps have been automated today,<br />

it is not possible to dispense with hand work in some areas.<br />

SHOEI <strong>com</strong>bines hand work and automation in production to<br />

ensure superlative quality. *You can find further details on the<br />

painting under the hand work heading.<br />

Final assembly<br />

The ventilation sliders, visor seals, inner shell and padding are<br />

assembled with great care. The helmet only goes for sale after<br />

the subsequent detailed final inspection.<br />

This strict <strong>com</strong>pliance with the production processes with<br />

associated quality control guarantees the constantly high<br />

SHOEI quality.

HAND WORK MAKES<br />

THE DIFFERENCE<br />

Hand work plays a significant role in the manufacture of SHOEI helmets.<br />

This is especially clear when we take the example of the painting<br />

Production &<br />

quality assurance<br />

After the helmet has been taken from the mould and all protruding<br />

parts and openings have been removed by a laser, the helmet is given<br />

its first priming. Then it is sanded and polished by hand and thus gets a<br />

flawless surface for the subsequent painting operations. Working on the<br />

various helmet shells with their own peculiarities requires a high degree<br />

of experience.<br />

Checking the priming<br />

After the priming the helmet is carefully checked for any small blemishes<br />

and passed for further painting – but only if the surface is absolutely<br />

perfect.<br />

The painting<br />

The quality of a painting operation depends on the quality of its individual<br />

layers. It is virtually impossible to apply a high-quality coat of paint<br />

by machine even with the very latest polyurethane paints. For that reason<br />

only specially qualified employees are used in this work step.<br />

Checking the painting<br />

Subsequently the paintwork is subjected to close inspection for drips,<br />

inclusions and unevenness.<br />

Applying the design<br />

Elaborate, extremely detailed and spectacular graphics are part of the<br />

brand image of a SHOEI helmet. In a very <strong>com</strong>plicated work step the<br />

designs are applied by hand by specially trained workers to the finished<br />

painted helmet.<br />

Protective varnish<br />

The last step in the painting process is the application of a clear varnish<br />

to the shell to protect the decoration and to give the helmet its unmistakable<br />

brilliance.<br />

The final inspection<br />

No <strong>com</strong>promise, even for invisible parts<br />

Before it is passed for final assembly, the finished paintwork of the helmet<br />

is given one last meticulous inspection. Perfection, even in areas<br />

that are hardly visible.<br />

QUALITY CONTROL<br />

Quality control in the development stage<br />

The country-specific safety standards play a<br />

major role during the development of a helmet.<br />

The helmet shell and the shock-absorbing inner<br />

shell are continuously tested for hardness and<br />

elasticity and modified as required. This results<br />

in a helmet that meets the strict standards that<br />

are applied and nonetheless still <strong>com</strong>bines all<br />

the advantages of the original design in itself.<br />

Quality control during production<br />

The SHOEI helmet<br />

Production &<br />

quality assurance<br />

Each helmet that leaves our factories in Ibaraki und Iwate had first been subjected to<br />

intensive quality control.<br />

Strict quality control tales places at SHOEI in all<br />

phases of production. From manufacturer of the<br />

outer shell up to final assembly. In addition to<br />

that, samples are regularly taken from normal<br />

production and tested at the <strong>com</strong>pany’s own test<br />

facilities. Every year more than 3,000 helmets<br />

are tested to ensure perfect safety and destroyed<br />

in doing so. These test helmets thus make a<br />

major contribution to the safety of our products.<br />

HANDLINg & CARE<br />

The right size and correct seating are of enormous importance for the safety and wearing<br />

<strong>com</strong>fort of a helmet. In addition, you should be aware that also helmets are subjected to<br />

an aging process. For that reason the way that a helmet is cared for makes a big difference<br />

to how long it lasts. Helmets can lose their ability to provide safety after a crash or due<br />

to aging and then they need to be replaced.<br />

Helmet selection<br />

There are many different types of helmets,<br />

whereby motorcycle helmets have to meet the<br />

toughest requirements of all. The minimum<br />

capabilities of motorcycle helmets are defined<br />

precisely by country-specific safety standards.<br />

Full face helmets offer the greatest level of<br />

Carrying the helmet<br />

Using both hands, the helmet is pulled apart at<br />

the chin strap and put on over the head with a<br />

safety and are ideally suited for sports-type<br />

riding and road racing sport. On the other hand,<br />

off-road helmets have advantages when used off<br />

the road. Each helmet should be selected with<br />

regard to the type of riding for which it will be used.<br />

rolling motion from front to back. The helmet is<br />

removed on the same principle.<br />

The correct way to put the helmet on How to take it off<br />

The right size<br />

Each model of helmet has<br />

small differences in its shape<br />

that affect the fit. For that<br />

reason it is essential to test<br />

the helmet before buying.<br />

Test whether it sits properly<br />

by putting on the helmet<br />

and moving your head to the<br />

left and the right and up and<br />

down while holding the helmet firmly with both<br />

hands. If your head can move too freely within<br />

the helmet, we re<strong>com</strong>mend that you try a smaller<br />

size. If you feel local pressure points, then<br />

choose a helmet that is one size larger or else<br />

adapt the helmet by pulling in the inner padding.


CARE OF THE HELMET<br />

The helmet shell<br />

All SHOEI helmets are made of <strong>com</strong>pound fibre materials.<br />

Therefore use plastic cleaner or wax to clean the helmet shell—<br />

but not on the ventilation slider and other plastic parts. Do not<br />

use polishes on helmets with matt finish paintwork.<br />

Plastic parts such as the visor, ventilation, etc.<br />

All plastic parts are very sensitive to solvents. Here we re<strong>com</strong>mend<br />

using only the mildest possible cleaning agents. The visor and any<br />

other parts that can be removed should be removed for cleaning.<br />

If the visor is equipped with a Pinlock system, this can also be<br />

cleaned with neutral soapy water. The visor and the Pinlock shield<br />

must be absolutely dry before the Pinlock system is reassembled.<br />

The inner padding<br />

All the parts of the removable inner padding should be washed<br />

by hand or in a washing machine at 30° C with the use of<br />

a washing bag. Antibacterial detergents have proven useful in<br />

removing smells. The inner shell can likewise be wiped down<br />

with a mild cleaner. Make sure that everything is absolutely dry<br />

before putting the padding back in again.<br />

When should a helmet be replaced?<br />

The life of a helmet depends on how it is used. A helmet<br />

should be replaced if one or more of the following points<br />

apply:<br />

1. There was a fall that resulted in an impact on the helmet.<br />

2. The helmet is worn as a result of very frequent use and has<br />

be<strong>com</strong>e wider.<br />

3. The inner shell has <strong>com</strong>e away from the helmet shell.<br />

4. The styrofoam (expanded polystyrene) inner shell shows<br />

signs of wear and is beginning to break up.<br />

Service<br />

If required, SHOEI will replace the inner padding, ventilation<br />

slider and inner shells as long as the helmet has not been<br />

subjected to an impact.<br />
