Privateer Superbike/Superstock 1000 racer Hayden Gillim suffered a horrifying crash last August at MotoAmerica’s race event at the new Pittsburgh International Race Complex, culminating in Gillim ragdoll-tumbling into a tire barrier at high speed while his GSX-R1000 cartwheeled and bounced all the way over the fence. The race was immediately red-flagged, as Gillim surely would be requiring prompt medical attention.

Surprisingly enough, Gillim emerged from the crash mostly unscathed! He was helped to his feet at the scene and was able to walk to the awaiting ambulance. A checkup and CT scan at the hospital revealed nothing worse than bruising on various body parts and no sign of a concussion. That’s a testimony to modern rider safety apparel.

In Gillim’s case, his head was ensconced in the Flex liner of the Bell Race Star he was wearing. The innovative Flex liner is designed to reduce rotational-force energy from affecting a rider’s brain during a crash, similar in concept to the Multi-Impact Protection System liner in Bell’s Star MIPS helmet.

Following the crash, Bell dissected the helmet to examine how it performed for Gillim. According to Bell’s engineers, the Flex liner apparently executed its job as it was designed to do, allowing Gillim to get back up and race another day.

Bell’s video crew documented the dissection procedure to help illustrate the benefits of the Flex liner’s design and to educate riders about how it performed during the crash to help prevent serious injury. Take a look at the video below to see how this horrifyingly ugly crash turned out amazingly benign.
