Looking at this...aside from the stupid remarks by the guy in the cage, and the fact that he did not stop to assist because he is judging a lot of books by their covers...appears to me the guy thought he was too hot going into the curve, hit the rear brake (notice the back end of the bike just before it straightens up and goes off the road) which stood the bike up, lost his lean angle, and the bike went straight, just as it is supposed to do. He just panicked in the middle of a turn and did the exact opposite of what he needed to do. Trailing rear brake is one thing, but he locked her up. Hope the guy didn't get hurt too badly.
The fact that the guy in the cage was freaking because he saw a bunch of HD "bikers" is a statement on how Joe Public views some of us, despite all efforts to dispell stereotypical concepts by the riders of HD bikes. Just shows to go you that a lot of them are still out there...
Yes...it looks like the Dragon to me...
