I used this on my FZR600 this past weekend for a 120 mile round trip tow. The center width adjustment was almost as short as it could be made. I would assume that it works with all sport bikes based on that. If you have wide bars it can adjust out very far.
haven't used these yet but put them on the 2010 goldwing in the garage and looks like they will work fine for what I need. Actually anchor the wing from front crash bars but these will add a nice back up attachement.
