Bell MX 2024 Moto-9S Flex Adult Helmet Pro Circuit 24 (Black/Blue)


Our industry-leading motocross and off-road racing helmet, now with a friendlier price tag, is as comfortable and safety-focused as ever.


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.
