Bell Moto-9S Flex Renen Nova Helmet
Back by popular demand is the redesigned Moto-9S Flex — the refinement of a long-standing industry leader. This strong, lightweight helmet carries over Bell’s time-tested traditions of performance and advanced safety standards. Packed inside are three material layers that help protect at different impact speeds and redirect rotation energy in many impacts. You still get the unbeatable ventilation of the flexible, segmented liner that adapts to the shape of your head for a custom feel. Top off this no-compromise design with our Tri-Matrix shell, delivering all the strength of carbon fiber in a more budget-friendly package for value that’s unheard of.

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.
