Bell Helmets has released its Moto-9 Flex micro site showcasing the innovations at the heart of its newest helmet. Originally unveiled at Intermot 2014, the Moto-9 Flex was developed in an effort to redefine and improve the means by which helmets manage energy across varying impact scenarios common with off-road motorcycling. The micro site highlighting the energy-management technologies may be viewed here: Introducing the Moto-9 Flex.

At the heart of Moto-9 Flex is Bell’s “progressive layering” technology – a system of three polymer materials, each designed to address specific impact velocities while simultaneously working in harmony to deliver Bell’s most comprehensive level of protection available today.

“Moto-9 Flex is a truly historic helmet for Bell, and the micro site captures not only the incredible attention to detail but the game-changing technology of the most advanced helmet we’ve ever made,” said Chris Sackett, Bell Helmets Vice President. “For more than 60 years, we’ve pushed the industry to expand the protective and performance capabilities of the modern helmet, and Moto-9 Flex once again raises the bar, setting a new standard for “state-of-the-art.”

Together with the Advanced Concepts Group at BRG Sports, Bell discovered Expanded Polyolefin (EPO), which actually works in tandem with the often used Expanded Polypropylene (EPP) and Expanded Polystyrene (EPS) layering systems. EPO is a soft and flexible low-density polymer that, when placed between the EPP and EPS layers, dampens low-threshold impacts. By combining these three materials at varying densities Bell has created an energy management system that excels in low, mid, and high-speed impacts. Along with the three potential impact speeds, Bell has addressed rotational energy management by engineering a “slip zone” within the Moto-9 Flex impact liner. The “slip zone” allows for subtle movement between the inner layers and works to reduce rotational energy transfer from angular impacts.

Bell also addressed head comfort with the Moto-9 Flex, using its “Adaptive Fit” system containing a segmented liner construction, which conforms to a rider’s head for a better fit and more predictable energy management. To also improve comfort, a Velocity Flow Ventilation system combined with a segmented liner offers maximum ventilation and temperature control.
