How a Helmet fits your head ?

To fit your head, you must measure your head with cm to make sure you buy the right size of the motorcycle helmet. (see the size table) fitting is important to retention for your safety.

Most helmets come with advice for fit and sizing. Most dealer accessory-sales personnel also have some training in fitting a helmet. Basically, the helmet should fit snugly so that it is stable when you shake your head side-to-side, front-to-back or up and down.

A full-face helmet should grip your cheeks and jaw as well as the top and sides of your head. A helmet that is too loose may come off in a crash, and one that is too tight will be uncomfortable (see the next section for more detail). If it only contacts the top of your head, that will soon become uncomfortable. Proper fit means that it is snug enough that your skin moves with it when you try to move the helmet on your head.

The fact that you wear a Medium in one brand and model does not mean that another model will fit you best in the same size, because of the shape of the helmet design.

For example, Open Face or Short helmets, which do not usually hold faces, will fit riders easily. Before buying, you should wear the helmet to make sure the correct fitting.

Though my preferred helmet is size M, I need an L in another model from the different maker and occasionally find a Medium that fits comfortably too. On the other hand, I can wear S-sized open face helmet comfortably.
