What I question with the Pitbull system is that if the front is not in a chock, wouldn't you still need to either strap down the front or lock the handlebars to the right cutting down on the space between two bikes side by side? If you did not do one of the two the front would be free to move around as you hit bumps and turn corners. That would not be acceptable to me. I have one Harbor Freight chock too that I haul the Honda with as it has a narrow front tire, and I have never had a problem with just straps in the rear. I guess having hauled bikes for over 30 years, I'm so impressed with the Baxley chock that I can't find fault with them with the exception of the cost. To spend $1000 on just chocks for the trailer took some long hard thought, but you know what, they are worth every penny. I would feel terriable if I opened up the trailer and saw my busa on it's side, or worse yet, open the trailer door to find one of my friends bikes down. The setup you have looks good with the exception of the straps you have. The type you just pull tight will not hold a heavy bike like the busa. You need a good set of ratchet straps.
