Built on the success of the Moto-9 range, the designers of the Bell Moto-9 Flex helmet set out to re-think the fit and build on the helmets longstanding ability to manage energy. Bell realize that heads come in a very varied range of sizes and shapes and wanted to deliver a more personalised, adaptive fit MX helmet. They managed to achieve this via its first-of-its-kind 3 layer impact liner that is designed to absorb low, mid and high energy impacts. The result is the most technologically advanced piece of head protection we've yet to see on the market for both motocross and off-road racing. For a seriously good-fitting helmet that can take a punch at any level of impact then check out the full range of Moto-9 helmets today and feel the difference for yourself.
