Product Care

What is the best way to clean the non-removable lining of my helmet?

To help keep the interior of your helmet in good condition never put your helmet away wet. Leave the visor open to allow air to circulate. It is also a good idea not to keep sweaty or smelly gloves or a balaclava inside the helmet as this can make the lining smell and it may become mouldy.

You can wash the non-removable inner lining with warm water and a mild hair shampoo. To dry either hang/place in a warm place or use a hair dryer on a very cool setting. It is important the helmet does not get too warm when drying as this could effect the EPS (Expanded PolyStyrene) lining.

Product Information

How do I find the Homologation standard and when does this expire?

The homologation labels can be found inside the crown of the helmet, sometimes just behind the lining.

Snell standards are updated every 5 years and are generally valid for 12-14 years from the start of the Snell standard; this varies according to FIA and national ASN regulations.

Snell SA2000 expires for FIA and national use on 1st January 2015.

How do I know if my Arai helmet needs replacing?

Arai helmets are handmade and use a really hard outer shell. After many years the shell can still look new but it’s the soft inner EPS polystyrene liner will loses its ability to absorb impacts. The liner gradually hardens over time and as you wear the helmet small compressions also affect the polystyrene.

Arai believes the helmet should be replaced after approximately 5 years of use or within 7 years from date of manufacture.

How do I find the Date of Manufacture?

The date of manufacture can be found by looking for the stamped date markings on the chin strap which show the month and year the helmet was made.

Do you offer a service for testing crashed/damaged helmets?

We don not offer a service for testing crashed/damaged helmets. We inspect damage to the surface of the helmet and the inner surface of the EPS liner in arriving at our opinion.

Helmet shells are made to be very strong so a drop from low heights are normally fine depending on the surface. The area you can’t see is the EPS (polystyrene liner) and the purpose of the EPS is to absorb energy during an impact. Since the liner is not removable there is no way of us telling if there has been any internal damage.

Often you are the best person to make the decision on whether it’s safe to wear as we an only giving an opinion – if in any doubt then we recommend you invest in a new helmet.


Can you replace the lining of a helmet?

Although the helmet EPS (polystyrene liner) and crown lining is not removable it is possible to replace the neck roll and aero chin flap. The helmet must be returned to us at Fyshe for this work to be udertaken. Cheek pads can be replaced and can be ordered from the accessories pages on our website.

Can you replace the chin strap of a helmet?

The Kevlar chin strap is very durable but should it become damaged or the Nomex covering of the uppers becomes badly frayed it is possible to replace the chin strap of the helmet. The helmet must be returned to us at Fyshe for this work to be carried out.

Getting the right size

Sizing Information

A better fitting and more comfortable helmet is a better performing helmet. It helps keep you alert, better focused and therefore a better driver. To achieve a perfect fit, different sized outer shells and different size and shaped inner shells are needed. Arai offers a wide choice of sizes, complete with replaceable cheek pads for a more customized fit. There are so many fit options that a perfect helmet fit should be achievable for most drivers.

Your Arai helmet will only perform at its best when you wear the right size. Therefore, Arai strongly urges you to try on the Arai model and size helmet that you are considering buying. The evolution of design technology, the changes in FIA and Snell requirements along with Arai's own changes and product advancements over the years can result in a different feeling of the current version of the model and size you've always worn.

Measuring your head
Start with measuring your head to get an idea of the size to look for: measure (in cm) the circumference across the forehead, above the eyes and ears and over the small bump at the back of the head, read the size where the tape joins.

Fit the measured size. Focus on your head size (crown fit) measurement first, e.g. the area contacted by a baseball caps' band. Do not be concerned with facial fit at this stage. When you can't get the helmet past your cheeks or jaws, do not conclude that it is too small and reach for a bigger size. The helmet must fit your head!

Remove the cheek pads and try on helmet sizes until you get that snug crown fit. For the most comfort the interior must fit snugly all around the crown of your head. You should feel some pressure at all the contact points around the interior perimeter, that too much pressure could become uncomfortable in the future.

Finally, Arai's optional cheek pad thicknesses, can fine-tune your personal fit. All Arai cheek pads can be replaced with a size that better suits your facial structure. However, this fit should be addressed only when the crown size is correct.

In special cases, Arai helmets can be custom fitted by one of our own Factory trained experts.

Arai offers 4 different sizes of outer shells. Unlike many other manufacturers Arai provides one size outer shell for each two helmet sizes for most models.

The advantage of using different shell sizes (instead of just one or two outer shells with more or less foam padding to stretch the size range) is the helmets inner shell and comfort material retains its correct thickness. This guarantees that all Arai helmets provide the same high graded protection. It also avoids a person having to wear an ‘oversized' looking helmet which, besides the cosmetic disadvantage, may lead to possibile added injury should an impact be sustained.

Besides the different shell sizes, another characteristic of Arai helmets is the use of different different shaped inner shells for different continents. One for Europe, one for Asia and one for North and South America since there are significant differences in head shapes in these regions.

Custom Fitting

Despite Arai’s many sizing options and variations, the helmet may sometimes have some pressure points that cannot be resolved by swapping the pads.

In this case Fyshe offers a custom fitting by pre-arranged appointment with one of our own Factory trained experts.
