that motorcycle rider looked like a total beginner. he had no control on that turn, and when he hit the first bike, he had his feet off the pegs and forward like they were going to stop him.
I really wish we didn't let total beginners get on 650 or 1000cc supersport bikes without some serious training first. yes, I know, that was probably a SV650, not exactly a supersport, but still a pretty serious motorcycle.
Experience is what you get when you don't get what you want.
