My research suggests a 5 inch rim, takes significant machining to align rear sprocket to front. Consider a wheel off an rs250 or for cheapness a cbr600 (I think an f3 model?).

You would want to change the front rim too or you will 'over tyre' the bike. I won't go into what it means it'll start an argument about geometry again.

I'm new to the nsr's so my response is really based on heresay and knowledge of 400's. Smile

HRC made wheels up to 5.25" for the rear of the MC21.
