Any of you guys got a Rocket Locker for your 12r? Ive been using a Chase Harper tail pack on mine. Ive been putting duct tape around the rear by the attach points to keep from scratching my bike when I use the pack on trips. Ive got a extra rear seat I had been considering just bolting the tail pack to using large flat washers but seeing this Rocket Locker Iam having second thoughts. The main thing we me is I dont want to scratch my bike.
