It takes a certain amount of bravery or a certain lack of preservative instincts to simply make the decision to ride a motorcycle. It takes the same traits on an entirely distant order of magnitude to attempt high-flying, never before done stunts on one. Josh Sheehan is hauling around a pair so hefty that their mass and momentum probably needed to be calculated as separate entities to make this stunt work: the triple motorcycle backflip. Just watch the video and try to tell me you’re not impressed.
He needed to hit the ramp at exactly 60 mph and then not spazz out and shart himself whilst soaring through the air like a boomerang.
