Shoei Helmet Sizing, Handling and Care

The right size and correct fitment are of enormous importance for the safety and wearing comfort of a helmet. Customers should be aware that helmets are subjected to an aging process. For that reason, the way that a helmet is cared for makes a big difference in how long it lasts. Helmets can lose their ability to provide proper safety after a crash or due to aging, in which case they should be replaced.

Helmet Selection

There are many different types of helmets. Motorcycle helmets have to meet the toughest requirements of all. The minimum capabilities of motorcycle helmets are defined precisely by DOT standards. Full-face helmets offer the greatest level of safety, and are ideally suited for sport riding and road racing. On the other hand, off-road helmets have advantages when used in their ideal environment. Each helmet should be selected with regard to the type of riding for which it will be used.

Correct Helmet Sizing

Each helmet model has small differences in its shape that ultimately affect the fit. For this reason, it is essential to test a helmet before buying it. Test whether it sits on your head properly by putting on the helmet and moving your head to the left and right, as well as 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 perhaps try on a different model.

Helmet Care

THE HELMET SHELL

All SHOEI helmet shells are made of compound fiber materials. Therefore, use plastic cleaner and/or wax to clean the helmet shell, but not on the ventilation slider and other plastic parts. Do not use polishes on helmets with matte finish paintwork. For these helmets, simply use a mild detergent and water for cleaning.

PLASTIC PARTS SUCH AS THE SHIELD, VENTILATION, ETC.

All plastic parts are very sensitive to solvents. For this reason, we recommend using only the mildest possible cleaning agents. The shield and any other parts that can be removed should be removed for cleaning. If the shield is equipped with a Pinlock system, this can also be cleaned with neutral soapy water. The shield and the Pinlock shield must be absolutely dry before the Pinlock system is reassembled.

THE COMFORT LINER

All parts of the removable comfort liner 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 EPS liner can likewise be wiped down with a mild cleaner. Make sure that everything is absolutely dry before putting the padding back into the helmet shell.

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 fits looser than when it was purchased due to frequent use.

3. The EPS liner has come away from the helmet shell.

4. The EPS liner shows signs of wear and is beginning to break up, or if it has been exposed to heat or a solvent and has melted.

SERVICE: SHOEI helmets are covered by a five-year, limited warranty, and SHOEI will repair or replace the helmet if it is found to suffer from flaws in materials or workmanship.

Shoei offers a free impact and safety inspection service for any SHOEI helmet.*
