Re: BMW S1000rr master cylinder on 954?
Five of us have spent time on the bike since I built it.
The bike has two foibles, very limited steering lock due to the much lower RG250 clip-ons I fitted, and the soggy shock common to all GPX250R's - nobody has compained about the brakes at all. My brother-in-law initially complained about the bars being too low but soon got used to it, the lower clip-ons are much more comfortable easily off-setting the minor annoyance of larger turning circles in carparks.
