Bell is renowned for their purpose-built solutions that provide amazing protection for the modern rider so when it came to developing the Moto-9 Flex race-proven helmet, they focused on building the helmet's longstanding ability to manage energy. And that is just what Bell did. Seeking out a better fit that is more adaptable, Bell has used the segmented liner from the Bell Segment bike helmet in order to achieve a fit for a variety of head shapes. The 3 layer impact liner which uses a revolutionary combination of polymer materials in order to provide a “progressive” energy management system, is designed to absorb low, mid and high energy impacts. The Moto-9 Flex has outperformed any other motocross helmet Bell has testes and is the more advanced helmet they have ever made. Setting a new level of protection for motocross and off-road racing, the Moto-9 Flex features quick flip visor screws, velocity flow ventilation and x-static interior, which is removable and washable. The Moto-9 Flex provides less energy and more protection.
