even if the trailer were illegal this guy should have seen the brake lights on the ducatti and the other red bike.
it looks to me like he was trying to play catch up, or hot shot, and got caught off guard
don't know that the ducati should have allowed him more room, it might have been nice but i dont see how a bike in front of this guy should be responsible to have eyes behind him and be the caretaker for a follower
if anything the zx10 should have gone wide left, or just applied the left side of his brain to operate his right wrist up, right fingers squeeze, and right foot down
it doesnt take a degree in physics to determine he might have been traveling too fast given the airtime and distance he got off his attempt at wingless flight, ka-kawwww
and i'm speaking from experience as a rider who has come in way too hot on more than one occassion
