lol.. I've watched it a dozen times now... and I still don't understand how he managed to come off..
The even funnier thing is that he was too kool for skool before he came off.. then he decides that a helmet might not be such a bad idea.. ehehhehe
Looks like he locked up the front brake in an attempt to not his the person in front of him after grabbing a fistful of throttle. Locked up, slid out, low-sided, got up, flexed, played it cool, got back on, nearly blew the engine, took off, died shortly after.
