That is crazy. Ive seen it before but it still amazes me. I have wondered (while riding) how these guys get off the bike and "ski" and then jump back on. I saw that on Biker Boyz and thought that was sweet- especially at night with the metal plates.
I suppose I can get my head around the getting your body off the bike part. It's the engine braking that gets me. They must have a throttle lock or something. I love the highway shot where he's casually looking at the camera while doing a one handed wheelie. This guy is smooth!
