clubmans fit on my 750K0 with little problem... there is a little over hang of the throttle grip, but only about 1/8 inch. i have it set up where the 'U' shaped curve of the clubmans is about level, with the points shooting forward instead of up at the sky... the grips are at a nice downward angle and a comfortable riding position. The banjo nestles snug up behind the right turn signal.. the 550 might have a tighter setup than the 750 though.. good luck
