Looks like he was about to rearend Melandri and got the rear wheel up in the air trying to stop as hard as he could. When the rear came back down it was plenty sideways and hooked up throwing the bike into a fit.Any longer vids? Say what happened? Guessing he hit the rear brake while it was in the air and when it settled down it started the wobble....???
To me it looked like the back tire broke loose heavy on the throttle as the bike became light going over that hump?
Pretty sure you did a move like this at the gap didnt you bud? lol
