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 different 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
  • 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
  • MERS (Magnefusion Emergency Removable System) magnetic cheek pad 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 5 year manufacturer's warranty
  • Meets or exceeds DOT and Snell M2015 certified
  • Matte Copper/Black/Red
