How to make sure your helmet fits properly

Pull outwards on each chinstrap to expand the helmet opening and slide it onto your head.
The inner helmet liner should fit snugly around your head.
Make sure that the top pad is seated against the top of your head.

For Full-Face Helmets, the cheek pads should fit snugly against your cheeks.

Fasten the chin strap and place one hand on each side of the helmet.

Put the helmet on. Fasten the chin strap, check for fit by moving helmet up and down as well as trying to rotate the helmet on your head.

Hold your head still and try to move the helmet up and down, and side to side. You should feel the skin of your head and face being pulled as you try to move the helmet. The helmet must fit snugly to offer maximum protection.

If you can move the helmet around easily, it is too big. Most helmets offer optional liner and cheek pad options to offer additional flexibility in fit.

Try sticking a pinky between your forehead and the helmet — you shouldn’t be able to get more than the very tip in. Good motorcycle dealers will have a staff that is trained to properly fit helmets to heads. These experts help customers find the helmet type and size that best fits their heads and needs.

Motorcycle Helmet sizing and lining shape are not consistent. Neither is head and face shape. You may find that the shape of the liner varies from brand to brand and that one offers a better fit for you over the others.

Try on a few brands/models of motorcycle helmets and compare how each size fits.

I hope that I have given you some factors to keep in mind as you do your research and shopping that will help you to make a more informed decision. Helping riders stay safe is very important to me.
