A careless biker’s poor handiwork resulted in a terrible crash at the Snetterton 300 in Norfolk.

Racer Joshua Boyd was struck by the debris and immediately knocked unconscious while traveling over 140 mph.

The debris turned out to be pieces of bodywork and bellypan that were loosely attached to a lead racer’s bike.

Boyd was lucky to be alive after slumping backwards on his BMW S1000RR and crashing at high speed. Fortunatley he wasn’t seriously injured and suffered a few nasty bruises and a black eye.

In the video below you can see the bodywork break free, but the impact with Boyd happens off camera. Seconds later, his limp form enters the frame before crashing off to the right side.

Boyd’s Pirelli racing team, Jones Dorling racing, was not pleased. They released the following statement after the crash.

“Not what we wanted to be sharing with you all after yesterday but Josh puts this precisely as it is. An accident that could’ve been prevented through proper procedure and proper checks!!! Thankfully Josh is ok and will be back racing ASAP.”
