Motocross Helmet Sizes – Size Guide & Available Options

In the Motocross Helmet Sizes category, you’ll find a clear overview of all available helmet sizes for off-road and enduro riding. Whether you need a smaller size like XXS or a larger size such as XXL, this is the place to find the perfect fit.

Why is the correct size important?

A properly fitting helmet provides optimal protection, sits comfortably and stays stable while riding. A helmet that is too tight or too loose can negatively affect both safety and riding comfort.

How to determine the right size

Use a soft measuring tape and measure around the widest part of your head, approximately 1 cm above your ears. Compare the measurement with the size chart. Choose a helmet that fits snugly without causing pressure points and doesn’t move excessively when you shake your head.

Which sizes are available?

Common motocross helmet sizes include XXS, XS, S, M, L, XL, XXL and XXXL. With this wide range, every rider—young or adult, small or tall—can find a helmet that fits perfectly.
