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-9’s 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. DOT approved. Meets the FMVSS 218 Standard. 7132146 S 7132147 M
