Hi ive got a 00(w) cbr 900 rrw and was thinking of swapping the tail unit with a more modern cbr unit.I was wondering has anybody done this mod and which unit is easiest to fit, also is it easier to buy the correct sub-frame or work with the existing frame.Im a fabricator by trade so ive got the skills and access to tools etc, would be interested in what you guys have to say and any pics of modified blades would be good, thanks chopper.
