What do you think caused this guy to dump? Downshift too far and locked up the back tire perhaps?

Looked like the bolt for the rear tire came off and the chain held it in place, but tilted the shit out of it and bam!
What an idiot for the dude with the video, where did he think that bike was going to go? Thru the turn?
Props for the good braking
