No one really associates Harley Davidson as a true stunt bike, but in this case we have two different riders on two different continents backflipping a Harley XR-1200.
Australasian Freestyle Motocross Champion Kain Saul did one in Australia and pro motocross rider Chuck Carothers did another in Prague during the Gladiator Games.
Both completed the stunts on 580lbs (263kg) Harley XR1200’s, but apparently there’s some controversy regarding who can claim the record, because Saul’s Harley was modified by Quick-Fix Harley Davidson dealer principal Gavin Walker, while Carothers did it on a stock XR-1200 with only a stiffened up suspension, but fell off after landing.
Carothers backflip after the jump.
