Introduction
QUALITY
MADE IN JAPAN
There is no other form of transport that gives a
sense of speed and of rounding corners dynamically than does the motorcycle. But this also
means that the motorcycle rider must always
reckon with a spill, whether on the race track
or an ordinary country road or in the town. It
is therefore essential for all riders to take suitable measures to protect against injury in a
crash, whereby the central and undoubtedly
most important element is the helmet.
At SHOEI highly specialized employees develop
and produce helmets on the basis of the very
latest technology, and to a large part this is done
by hand. Thanks to decades of experience and
our passion for helmet technology, millions of
passionate motorcycle riders place their trust in
the SHOEI brand.
With its company headquarters in Japan and
further locations in Europe and the USA, SHOEI
reaches its customers in almost 40 countries
around the globe and thus belongs to one of
the leading brands in the international helmet
segment.

OUR PHILOSOPHY
SAFETY
COMFORT
PASSION
Three factors – A first class helmet
Of course, the main function of a helmet is to
protect the head of the rider in the event of an
impact. However, we have defined the requirements concerning SHOEI helmets in a more
comprehensive way. Consequently the basis of
our product philosophy is 3 core aspects:
the safety of the impact protection, a maximum
degree of comfort in any situation and the passion
for motorcycling have been the basis for the
development of all SHOEI helmets since 1959.
Introduction
Philosophy & safety concept
THE SHOEI
SAFETY CONCEPT
In addition to the basic safety properties that ensure protection in the event of an impact, there
are also the comfort aspects that characterise an outstanding helmet. A comfortable helmet
makes a decisive contribution to relieving the load on the rider and helps his concentration – an
important constituent part of the SHOEI safety concept.
Passive safety – active safety
Ensuring its helmets comply with the various
standards worldwide for passive safety takes top
priority at SHOEI. Our strict quality assurance
ensures that this applies at all times and for
all SHOEI helmets. But our products have also
made a number of contributions to active safety.
For example, the aerodynamics, the comfortable
padding and the efficient ventilation of our helmets all help the rider to concentrate on the one
important thing: driving safely.

WHAT MAKES A SHOEI
HELMET STAND OUT
Of all types of helmets, a motorcycle helmet is the one that has to meet the toughest requirements concerning its protective function. Its strong outer shell and its broad impact protection
distinguish it fundamentally from other types of helmets.

The constituent parts
and their functions
1
The visor
The visor protects the rider against wind, dirt, insects and UV radiation, but
at all times it must also guarantee clear vision without any optical distortion.
2
The helmet shell
The helmet shell absorbs the impact energy in the event of a fall and distributes it over the largest possible area.
3
The EPS liner (inner shell)
The energy that is passed on by the helmet shell is taken up by the shockabsorbing inner shell and ensures a maximum degree of safety. The helmet
inner shell consists of light, shock-absorbing polystyrene and is pressed
together in the event of an impact.
4
The inner padding
The inner padding consists of high-quality polyurethane foam of various
levels of hardness with covers of pleasant padding materials and ensures a
perfect hold and pleasant seating.
5
The chin strap
The task of the chin strap is to hold the helmet firmly on the head. This
is done by using a chin strap whose tensile strength and extensibility are
matched especially to this function. The chin strap is firmly attached to the
helmet shell by means of metal rivets.
6
Ventilation
The SHOEI ventilation system directs the wind from the speed of travel into
the helmet and guides warm and damp air to the outside. Ventilation is one
of the elementary and important innovations in the equipment of our more
recent models. The perfect placing and shaping of the inlets, outlets and channels is the basis of optimum ventilation and requires a very special know-how.

Technical Book
PASSIVE SAFETY
The impact protection for the head is used to provide passive safety and is, as explained
above, a major constituent part of the SHOEI safety concept. The performance of a helmet with
regard to passive safety is measured on the basis of various international safety standards.
Thanks to many years of know-how and our commitment to quality assurance, the performance
properties of all SHOEI helmets are clearly above the requirements of these standards.
The ECE R22/05 standard
A number of safety standards have established
themselves worldwide and they differ markedly
from one another concerning their criteria and
test scenarios, in accordance with the requirements in the various countries. The ECE R22/05
Directive applies in all the countries of the ECE
(Economic Commission for Europe) and those
countries that have associated themselves with
this standard. Helmets that do not comply with
this Directive may not be sold in the relevant
countries of the ECE – with few exceptions.
The ECE R22/05 standard tests among other
things the impact damping, the chin strap, the rolloff behaviour, the structure and the resistance.
Two criteria are tested in the impact damping
test. On the one hand, the permissible value
for the maximum acceleration is measured in g
(Peak G) and on the other hand the HIC (Head
Injury Criterion), hence the risk of injury for the
head. The HIC represents the total amount of
energy that acts on the head and is calculated
from the impact speed and the length of time
that the force acts. The maximum permitted
values of 275 g and 2400 for the HIC are
handled very strictly in the ECE countries. The
special properties of the outer shell, the high
shock-absorbing ability of the inner shell and
absolute quality assurance ensure that SHOEI
meets these stipulations at all times and shows
the very best results.
The inner shell of a SHOEI helmet
In accordance with its high level of quality, each
SHOEI helmet that is offered for sale in Europe is
given a shock-absorbing double inner shell with
a special shaping. The combination of the various grades of expanded EPS provides an effective damping of shocks and impacts and at the
same time for a low HIC value. The upper part
of the helmet inner shell is generally softer than
the outer edge. The relatively hard edge of the
inner shell increases the damping effect in the
event of a crash and provides a low HIC value.
The technology has been patented and is regarded as the technical property of SHOEI.

ACtive SAFETY
As opposed to “passive safety” that is ensured by compliance with the various country-specific
safety standards, “active safety” means an improvement in wearing comfort to allow the rider
to devote his full concentration to driving.
Product properties such as improved inner padding for optimum seating of the helmet, the
lowest possible weight to reduce stress on the neck muscles, an effective ventilation system for
temperature regulation and a reduction of wind noises primarily serve the safety of the rider.
This underscores the importance of the continuous further development of SHOEI helmets in
the area of comfort technology.
The inner padding
The interaction of wearing comfort and proper fit
The material and the shape of the inner padding are decisive for
the wearing comfort and proper fit of the helmet. The wearing
comfort covers the effect of the material properties on the skin
of the rider. The fit defines how well the helmet sits on the head
and stays in place and is especially noticeable at high speeds.
In the past these two criteria often worked against one another.
Very thick, soft padding provided good wearing comfort, but it
did not hold well at high speeds and led to wobbling.
SHOEI rethought the structure and function of the inner padding
and developed a new concept. The inner shell of the helmet was
shaped to the head, and thus, thinner padding can be used.
This in turn is produced in a complicated process either from
multiple layers of polyurethane foam of different hardnesses or
else is cut three-dimensionally from a block so as to ensure
optimum hold together with high wearing comfort.

Optimisation of the cover materials
The development of new high-performance fabrics allows
the function of the padding with regard to taking up sweat
to be optimised to the extent that we can talk of a “summer
covering”. This is used in the first instance in motocross
and in road racing sport where the amount of physical exertion and hence the production of sweat is extremely high.

Active safety
Savings in weight and aerodynamics
Improved safety through lighter helmets
Three factors are crucial for the weight of the
helmet as perceived by the rider. The actual
weight that is felt by wearing the helmet, the felt
weight and the dynamic weight which is pro-
duced by the wind resistance and inertia. The
actual weight has a direct influence on the acceleration forces and directly stresses the neck
muscles in the event of an accident.
The helmet shell that has been optimised for weight
The heaviest part of a helmet is the helmet shell
and this is of special importance when making a
light helmet. Since the shell is also the part of the
helmet that is the most stressed in the event of an
impact, the requirements concerning the manufacture of a light helmet shell are correspondingly
high. Through its extensive experience in the processing of fibre compound materials, SHOEI has
succeeded in developing the extremely resistant
and light AIM and AIM+ helmet shells.

SHOEI AIM stands for “Advanced Integrated Matrix” and is made up of three main features:
1. Shaping process with fibre-reinforced layer
matrix. Generally, an outer shell that is made
of fibreglass (FRP) is given its shape by a
heat-setting plastic. The SHOEI outer shell
owes its ideal function to the integration of organic fibres and of three-dimensional shaping
in a layered structure. This produces a helmet outer shell that is characterised by high
strength for a very low weight as compared to
shells that are produced in a conventional way.
2. The compound structure. The AIM shell
consists of various layers of reinforcing organic
fibres and glass fibres. Compared to an outer
shell that is only made of glass fibres, the AIM
outer shell is both lighter and more elastic for the
same strength, and the AIM+ outer shell is even
lighter due to the additional use of special fibres.
3. The synthetic resin. A specially modified,
unsaturated polyester resin, a so-called heatsetting plastic, is used for the AIM outer shell.
This resin acquires the desired strength and
elasticity during the heat hardening process.
This synthetic resin is also extremely resistant to
corrosion for good measure.

Thus the outer shell and the inner shell may show damage from deformation after an impact, but the head of the rider
is given the maximum amount of protection as a result. Heavy, hard helmet shells do not have this ability and direct
the energy from an impact without any reduction into the inside of the helmet. In many cases the shell may be undamaged but it was not possible to avoid head injuries. This applies in particular to helmets that were primarily designed
to prevent penetration by sharp objects.
Improving the aerodynamics
The stress applied to the neck muscles when
riding a motorcycle comes not only from the
weight of the helmet itself but also, above all,
from the air resistance. For that reason improving the aerodynamics is an important factor in
preventing the onset of tiredness. The SHOEI
product development section regularly makes
tests in its own wind tunnel to design helmets
with optimum aerodynamic properties.
Ventilation
Back in the early 1980s SHOEI developed a
ventilation system that passed air through holes
in the helmet shell without affecting the stability
of the outer shell. The idea that good ventilation is crucial for the safety of a helmet caused
a fundamental change in the design of motorcycle helmets. This once again makes it clear
how important the safety concepts and a spirit
of innovation are at SHOEI. The investment in
a wind tunnel of our own allows us to carry out
intensive studies in the development of effective
and high-performance ventilation systems.
SHOEI has developed a dual EPS liner (inner
shell) whose air system allows an optimum exchange of warm, used air and incoming cold
fresh air.
The dual EPS liner, a
2- or 3-layer impactdamping shell, was
developed by SHOEI.

Active safety
The SHOEI visor system
The visor protects the rider against wind, dirt
and insects. In addition to full face helmets,
many open helmets and half helmets are also
provided with a visor. All SHOEI visors are made
of polycarbonate. Most of them are produced by
the so-called injection moulding process. This
guarantees clear and distortion-free vision. Furthermore, the visor protects against small stones
and absorbs 99% of the UV radiation, its coating
prevents scratches and lets water roll off more
easily in beads. Except the Hornet-DS model all
visors are provided with SHOEI’s own Q.R.B.P.

Noise exposure
A high level of noise imposes unnecessary stress
on the rider and disturbs his concentration. There
are two ways to reduce noise in the helmet
through suitable design. On the one hand, wind
noise can be reduced by optimising the aerodynamics. On the other hand, the acoustic damping
properties of the helmet can be optimised by
suitable design of the helmet shell and the padding. The decisive factor for a comfortable and
quiet helmet is the balanced utilization of these
two approaches. Reducing the noise through a
thicker helmet shell, doing without ventilation or
using padding that is too tight may reduce the
amount of noise experienced, but this is achieved at the expense of safety and comfort and
hence is not an option for SHOEI.

helmet more extreme than in professional racing sport. The development of SHOEI sports
helmets is decisively supported by our factory

classes. Among other things, the ventilation system and the quick-change visor system were
developed first for racing sport. Today every rider with a SHOEI helmet can benefit from these
technologies.

Production &
quality assurance
For all the energy and passion that are invested in the development of a product, in the
last resort the quality in series production must comply with the specifications from the
development section. The following explains on the basis of the manufacturing process
what it is that makes up the unique quality of SHOEI helmets.
Production of the helmet shell
SHOEI exclusively uses fibre-reinforced plastics that offer the
best properties for the manufacture of a helmet shell. Thanks
to having many years of experience and highly specialised employees, SHOEI is in a position to produce helmet shells that
are extremely strong and yet light. Each helmet shell is marked
personally by the employee who is responsible for it and thus
puts his name on the line for the quality of this example.
Laser cutting
Here the helmet is given its final shape. All the protrusions that
area created in manufacture are cut off. The openings for the
visor and ventilation are burnt into the helmet shell with a laser.
Finally the helmet is checked to ensure that it has the correct
material thickness and weight.
Painting
Even though many production steps have been automated today, it is not possible to dispense with hand work in some areas.
SHOEI combines hand work and automation in production to
ensure superlative quality. *You can find further details on the
painting under the hand work heading.
Final assembly
The ventilation sliders, visor seals, inner shell and padding are
assembled with great care. The helmet only goes for sale after
the subsequent detailed final inspection.
This strict compliance with the production processes with
associated quality control guarantees the constantly high
SHOEI quality.

HAND WORK MAKES
THE DIFFERENCE
Hand work plays a significant role in the manufacture of SHOEI helmets.
This is especially clear when we take the example of the painting

The priming
After the helmet has been taken from the mould and all protruding
parts and openings have been removed by a laser, the helmet is given
its first priming. Then it is sanded and polished by hand and thus gets a
flawless surface for the subsequent painting operations. Working on the
various helmet shells with their own peculiarities requires a high degree
of experience.

Checking the painting
After the priming the helmet is carefully checked for any small blemishes and passed for further painting – but only if the surface is absolutely perfect.
The quality of a painting operation depends on the quality of its individual layers. It is virtually impossible to apply a high-quality coat of paint
by machine even with the very latest polyurethane paints. For that reason only specially qualified employees are used in this work step.
Subsequently the paintwork is subjected to close inspection for drips,
inclusions and unevenness.

Quality control
Each helmet that leaves our factories in Ibaraki und Iwate had first been subjected to
intensive quality control.
Quality control in the development stage
The country-specific safety standards play a
major role during the development of a helmet.
The helmet shell and the shock-absorbing inner
shell are continuously tested for hardness and
elasticity and modified as required. This results
in a helmet that meets the strict standards that
are applied and nonetheless still combines all
the advantages of the original design in itself.
Quality control during production
Strict quality control tales places at SHOEI in all
phases of production. From manufacturer of the
outer shell up to final assembly. In addition to
that, samples are regularly taken from normal
production and tested at the company’s own test
facilities. Every year more than 3,000 helmets
are tested to ensure perfect safety and destroyed in doing so. These test helmets thus make a
major contribution to the safety of our products.

Handling & care
The right size and correct seating are of enormous importance for the safety and wearing
comfort of a helmet. In addition, you should be aware that also helmets are subjected to
an aging process. For that reason the way that a helmet is cared for makes a big difference
to how long it lasts. Helmets can lose their ability to provide safety after a crash or due
to aging and then they need to be replaced.
Helmet selection
There are many different types of helmets,
whereby motorcycle helmets have to meet the
toughest requirements of all. The minimum
capabilities of motorcycle helmets are defined
precisely by country-specific safety standards.
Full face helmets offer the greatest level of
safety and are ideally suited for sports-type
riding and road racing sport. On the other hand,
off-road helmets have advantages when used off
the road. Each helmet should be selected with
regard to the type of riding for which it will be used.
Carrying the helmet
Using both hands, the helmet is pulled apart at
the chin strap and put on over the head with a

removed on the same principle.
How to take it off
The right size
Each model of helmet has
small differences in its shape
that affect the fit. For that
reason it is essential to test
the helmet before buying.
Test whether it sits properly by putting on the helmet
and moving your head to the
left and the right and up and
down while holding the helmet firmly with both
hands. If your head can move too freely within
the helmet, we recommend that you try a smaller
size. If you feel local pressure points, then
choose a helmet that is one size larger or else
adapt the helmet by pulling in the inner padding.
The SHOEI helmet
Handling & care
CARE OF THE HELMET
The helmet shell
All SHOEI helmets are made of compound fibre materials.
Therefore use plastic cleaner or wax to clean the helmet shell—
but not on the ventilation slider and other plastic parts. Do not
use polishes on helmets with matt finish paintwork.
Plastic parts such as the visor, ventilation, etc.
All plastic parts are very sensitive to solvents. Here we recommend
using only the mildest possible cleaning agents. The visor and any
other parts that can be removed should be removed for cleaning.
If the visor is equipped with a Pinlock system, this can also be
cleaned with neutral soapy water. The visor and the Pinlock shield
must be absolutely dry before the Pinlock system is reassembled.
The inner padding
All the parts of the removable inner padding should be washed by hand or in a washing machine at 30° C with the use of
a washing bag. Antibacterial detergents have proven useful in
removing smells. The inner shell can likewise be wiped down
with a mild cleaner. Make sure that everything is absolutely dry
before putting the padding back in again.
When should a helmet be replaced?
The life of a helmet depends on how it is used. A helmet
should be replaced if one or more of the following points
apply:
1. There was a fall that resulted in an impact on the helmet.
2. The helmet is worn as a result of very frequent use and has
become wider.
3. The inner shell has come away from the helmet shell.
4. The styrofoam (expanded polystyrene) inner shell shows
signs of wear and is beginning to break up.
Service
If required, SHOEI will replace the inner padding, ventilation
slider and inner shells as long as the helmet has not been
subjected to an impact.
