I had mine fitted by my dealer while it was in for a few other jobs, so I don't know exactly what needed doing. I think they bolt straight on but they don't have the necessary threaded piece inside the ends for the std bar end weights, I'm sure other will chime in with full details.
What else have you got planned?
I've been blacking out my 05 Rocket. I started before Roadster came out or I just would have bought one of those. I've done peg mounts, rear frame rails, backrest and luggage rack, lower fork guards and am now doing triple clamps and bars
