The world's first Harley backflip to dirt occurred yesterday, but depending on who you believe, it was either Kain Saul in Australia or Chuck Carothers in Prague. Both completed the stunt on a Harley XR1200, but there's some controversy over who really deserves the record. Kain's bike was heavily modified with MX-style suspension, Chuck failed to stick his landing. Videos of both jumps are below
