Fortunately for me, the conversion is a fairly common one for NSR50s over in Japan, and there are multiple bolt up kits to do the deed using an NSR50 front wheel and rotor. The only real question at the moment is weather or not you use a stock NSR50 axle and spacer set, or if there is a separate set for the conversion.

I just happen to have an NSR50 front wheel and rotor... and my bike already accepts NSR50 compatible stem setups as is. The only tweak I have to make is welding on a forward facing steering stop.
