Sorry you are year late I sold mine to 1olbul about this time last year I think but I can tell you they are great value only sold mine cos I was getting a Corbin Seat with backrest
I just got one a couple of weeks ago, but I'm selling the 2011 Rocket III Roadster I had it mounted on. It mounts to the bracket that mounts the passenger's seat. Does $100 sound fair? 239.822.5625
