I think it was that chain link front end broke on him. Is that what happened? I never saw the whole thing that was filmed. ERC
Wow, how stories get twisted.
First of all, he wasn't on the Chain Bike. He was on Grease Monkey.
The fall happened after the main event was over. It happened out in the parking area. All the other bikes were in the trailer. The crowd pressed him to do a stand up & he rode Grease Monkey because it was still out. It did not have a throttle lock as the other bikes he normally did stand ups on did.
So when he stood up, the bike started to slow instead of keeping a steady speed. He stayed up a hair too long, the front end wobbled & down he went.
