Old topic, but wanting to see if others are having same results as I.
I ordered this backrest mount from badboyz just a couple months ago. So from reading this thread, mine should be the heavier SS version as its been almost a yr since the updated version. I'm only 155lbs and this one flexes just by resting against it. Plus it does not have the added welded reinforcement angle. (not the 1st redesign with gussets, but the doubled up steel) Also, only the upper half is SS. The lower piece is steel. I'm thinking mine is an old one?? Which would explain why I'm not enjoying the same positive reviews that several here are. Somewhat dissapointed as the flex offers little back support for me. I may weld the reinforcement piece in and repowder coat mine, but Im also concerned about the bolts and the fender. Theres alot of leverage working against them. Afraid the fender could be bent if for some reason someone leans to hard against backrest. I might look into redesigning the lower piece entirely to also attach to the bolts near battery like the HD mount does, if space permits, taking the leverage force off the fender bolts. At least now I have a pattern to work with vs, starting from scratch. I'm a toolmaker and considered making one from day 1, but decided to just buy this instead.
