It's not a Hawk; it's a Ducati and a couple of stunt bikes, but like that makes it worse. This guy is just plain awesome. Most of the time he only has one tire on the ground, and if he has two on the ground, one of them is on fire.

Halfway through he hops onto a bike that only has a rear wheel and shocks the crowd.

EDIT: Sorry, wrong forum. It's just I hadn't seen a new post in the video forum since I joined, so it sort of erased from my consciousness.
