This sizing chart is based on information provided to us by Bell Helmets and is subject to change without notice, although we will do our very best to keep it up to date. We recommend that you measure your head by wrapping a cloth tape measure around your head about 1 inch or 2.5 cm above your eyebrows, which should be the largest portion of your head. Choose the helmet that is closest to your measured head size. If you fall between two sizes, choose the smaller of the two. You want a helmet to fit snug without being uncomfortable.

Our Two Cents
Bell says: Ever since the first Bell helmet, our ongoing mission has been to innovate and improve the science of protection, always striving to bring technologies to the table that set the benchmark for impact and energy management. Meet the Moto-9 Flex evolution of the fittest. A first-of-its-kind, three-layer impact liner utilizes multiple densities of material to more comprehensively disperse impact energy and works to reduce rotational energy transfer. Moto-9s flexible, segmented liner achieves an adaptive, more personalized fit for a wider variety of head shapes, and allows us to deliver superior ventilation throughout the helmet. The Moto-9 Flex is the most advanced helmet we have ever made and is setting the standard for rider protection in motocross and off-road racing.
