Too Big, Too Small, or just the wrong Size, NO WORRIES.
We offer a Free Size Exchange Or we will help you customize the fit with different size cheek pads or a different size Interior Liner.

HOW TO SIZE YOUR HELMET: When buying a helmet it is important to ensure that you have measured your head correctly.
Due to varying head shapes, heads that are the same size when measured by a tape may not necessarily fit the same size helmet. Please see our Arai Head Shape section to get more information.

It is important to measure the circumference of your head from above your ears, passing the tape measure over the center of your forehead, and over the natural bump that everyone has at the back of their head resulting in the largest possible measurement. If you have longer or shorter hair, there may be some tolerance either way. So if you prefer a tight fit, we recommend a smaller size and if you prefer a loose fit, go for the bigger size. Take several measurements to make sure you have the correct one.

The correct way to measure your head:
Measuring your head for a helmet
Note: After measuring your head you may find yourself between sizes on the Arai sizing chart when this happens you should opt for the smaller helmet size, as the interior helmet padding will give way relatively quickly, and will ensure your head fits snugly.

After receiving your new helmet, please try it on for size WITHOUT removing the shield sticker:

Helmets used on a bike or with the shield sticker removed cannot be returned for an exchange or credit.
INTERIOR LINERS: All current Arai motorcycle helmets have removable liners, these are available in many sizes to customize the helmet for a better fit.

CHEEK PADS: All Arai Motorcycle Helmets, Newer Arai Auto helmets and Arai Karting Helmets have easily removable cheek pads to help you further customize the size of your helmet for a perfect fit. These cheek pads are available in many sizes.

SPECIAL NOTE: On current Arai Motorcycle Helmets, by changing the interior liner and the cheek pads, it is possible to change the helmet half a size either way. To make the helmet bigger, use the thinnest interior liner and thinnest cheek pads. If you want to make it smaller, just use the thick liner and cheek pads.

If you have any question regarding sizing, please feel free to call us or email, we will be happy to help you.
