I just got off the phone with Scotts about getting a Damper. The kit will NOT support Rox risers. Also to use the kit they make for the LRP you would also need to be using 7/8 bars without cross bar. It also would NOT work with HDB's top bar mount as the Damper kit comes with the top clamp. I have Rox risers with 1 1/8 protaper HDB set up. They were very helpful and listened to my needs and are going to see what they can do for me using the universal set up ... just some FYI for ya. I can update later if anybody wants.
