3D Configurator


The initial step in choosing your perfect NACA motorcycle helmet is to determine which size fits you best. The method is simple and only requires a tape measure. You will need to measure the circumference of your head by following these steps:

1. Position the tape measure halfway across your forehead.

2. Wrap it around your head, from the back, at the occiput.

3. To ensure an accurate measurement, it is recommended to repeat this procedure at least three times.

Once you have it, simply consult our NACA motorcycle helmet size guide to determine which size is best for you.

Each size in our range of motorcycle helmets is designed to adapt perfectly to your measurement, ensuring optimal comfort and safety.
