I just installed the Yamaha Raider Quick Detach Backrest (Short Style) on my bike tonight. I like the solo look of my bike, but when the wife or pretty soon my grand daughter want to go, the suction cup seat along with the quick release backrest is a great set up for that last minute setup change. I did not know it when i ordered it, but it has a key lock so the quick release cant be removed while locked. (locks only keep honest people out).
I have a 240 rear tire, and the bolts that came with it go thru a bit to much for my liking, so I cut about 1/8 inch off each bolt so they are flush on inside of fender when tightened.
The set up cost me just under $400 from honda east in toledo...that was with free shipping.
