KX of Death

While visiting in California on vacation, my friend John in Long Beach, who has a Ph.D in mechanical engineering, let me ride his tiny KX80 dirt bike which had a built 550cc KX500 engine in it making, oh, 70 hp. The bike is literally 70hp in a 15 hp bag, and it vibrates like an evil paint shaker from hell. Hilarity and near death predictably ensued. Dunno why anyone would want such a ridiculous toy, but what the hell, life is short and interacting with this evil little beast could make it shorter!
