Here is a horrible cell phone pic. Michael, feel free to chime in with some mounting tips. I wanted to try to keep the bags forward of the rear axle. I also wanted to keep the "flaps" slightly above the seat. The mounted "buttons" are pretty close to my rear seat. I did this because the plastic is not anchored anywhere after the rear seat bolts on the WRR/X. I may regret this when I try to mount a (future purchase) US series bag. The opposite side looks weird because I tried to tuck it in to the gigantic stock exhaust. That bag sits much more angled.
