The Moto-9 Flex is the most advanced helmet Bell Helmets has ever made. Designed to manage linear and rotational energy to the head in certain low, mid, and high speed impacts - the first of its kind, three layer impact liner made from a revolutionary combination of polymer materials provides a "progressive" energy management system. Leveraging the segmented liner from Bell's Segment bike helmet, the Moto-9 Flex offers a more personalized, adaptive fit, for a wide variety of head shapes. The Bell Moto-9 Flex is quickly setting a new level for rider protection in motocross and offroad racing.

  • Composite carbon shell construction with a three layer impact liner designed to manage energy from three potential impact scenarios: low, mid and high speed
  • EPP (Expanded Polypropylene) inner layer for mid speed impacts up to 5 meters/second
  • EPO (Expanded Polyolefin) flexible middle layer for low speed impacts (3 meters/second)
  • EPS (Expanded Polystyrene) outer layer for high speed impacts (7.75 meters/second)
  • As the impact becomes greater, higher density layers are engaged to manage energy
  • A "slip zone" within the impact liner allows for subtle movement between the inner layers and works to reduce rotational energy transfer from angular impacts
  • Segmented construction automatically conforms to a rider's head for a better fit and more predictable energy management
  • Fully ventilated EPS lined chinbar
  • Integrated vented roost guard
  • Fully adjustable Flying Bridge Visor with air intake vents
  • QuickFlip visor screws for easy adjustment, even with gloves on
  • Velocity Flow Ventilation system for maximum cooling
  • Removable/washable X-Static XT2 silver liner
  • Extended Wear interior
  • MERS (Magnefusion Emergency Removable System) magnetic cheekpad system allows for easy helmet removal in emergency situations
  • Used in conjunction with the Eject Helmet Removal System, MERS allows first responders to gently remove the helmet from a rider's head, reducing the potential for secondary neck or spine injuries
  • Padded chin strap with D-ring closure and exclusive Magnefusion magnetic strap keeper
  • Padded/lined helmet bag included
  • Industry leading five year manufacturer's warranty
  • DOT and Snell M2015 certified
