Nobody has ever before attempted to backflip a Harley-Davidson motorcycle and when the idea finally struck, it did in two different heads, that of Kain Saul in Australia and Chuck Carothers in Prague. They both recently performed their backflips on Harley-Davidson XR1200 motorcycles, meaning that both deserve our recognition and appreciation, despite the fact that the XR1200 used by Kain was specially-prepped for the job while Chuck’s much more rigid XR1200 threw him to the ground. See both videos after the jump.
