Sizing

Measuring for a motorcycle helmet is important. Get a helmet that is too small, and you’ll end up with a headache and a very uncomfortable ride. Get one that is too big, and you might as well wear a hat, since that’s about all the protection you’ll enjoy. A helmet needs to fit properly, with a very slight movement when tugged by your hand. So getting the right size measurement of your head is very important.
