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 />

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 />

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 />

developed by SHOEI.<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 />

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 />

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.

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 />

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 />
