Size and fit guide: choosing the right shape and size for your Arai helmet

Choosing an Arai helmet means opting for quality and safety. But to fully enjoy its performance, it must be a perfect fit for your head. A poorly fitting helmet, even a high-end one, loses comfort, protection, and riding pleasure. Here's a complete guide to finding the right size and the ideal shell shape for your head shape.

Why the right fit is crucial

• Safety : A helmet that is too large may move in the event of a fall. If it is too tight, it can cause pain.

• Comfort : pressure points on the forehead or temples can ruin even a short journey.

• Soundproofing and ventilation : a well-fitting helmet reduces background noise and improves airflow.

At Arai, every detail is designed to allow for a custom fit.

Measure your head circumference correctly

Take a flexible measuring tape and measure the circumference of your head , passing over your forehead (approximately 2.5 cm above your eyebrows) and the back of your skull. Note the measurement in centimeters.

The 3 Arai shell shapes: Round Oval, Intermediate Oval, Long Oval

Arai is one of the few brands to offer different internal shapes to adapt to different body shapes:

• Round Oval : for short and wide heads (less common in Europe)

• Intermediate Oval : the most common shape, suitable for the majority of European motorcyclists

• Long Oval : for longer, narrower heads

Most models sold in France are in "Intermediate Oval", but some series offer other formats on request or via adaptive accessories.

Custom fit: interchangeable foam and cheek pads

All Arai helmets allow for a very fine adjustment thanks to their internal foam padding:

• Cheek foams in various thicknesses

• Cuttable shell foams (Peel-Away system)

• Customization kit available on certain models (Quantic, RX-7V EVO...)

This helps to avoid pressure points or areas of slackness.

Fitting tips

• The helmet must fit snugly all around the head.

• When you shake your head, it should not move

• The jugular vein strap must be properly adjusted, without hindering swallowing.

• Wear it for 5-10 minutes to check the comfort over time.

If in doubt: consult an expert

An Arai helmet is an investment. It is strongly recommended that you seek advice from an authorized dealer or expert before purchasing. They can check the size and shape, and offer a precise fit.
