What Shape Are Arai Helmets? (A Reference Guide)

ByMichael Stephenson Updated on

Finding a motorcycle helmet with the right shape can be a tricky thing to do. This can be particularly difficult with cheaper helmets.

Now it is no secret that Arai helmets are expensive. However, Arai offers helmets of different shapes and sizes in an effort to meet the demands of riders and allow them to find the perfect fit. (Which is just one of the reasons why expensive motorcycle helmets are worth it.)

Arai motorcycle helmets come in three different shapes: intermediate oval, long oval, and round oval. The majority of Arai helmets are intermediate oval, and a smaller percentage of Arai helmets are long oval and round oval. Arai helmets also come in various sizes, from XS to 3XL.

A long oval head shape means the length of the head is longer than the width. A round oval means that the length of the head and the width are somewhat similar. The intermediate oval is the most common head shape, which is somewhere between the long oval and the round oval.

Below you can find a quick reference list going over more than 70 different Arai helmets that can be found on the market today.
