Moriwaki-man
Thanks for trying to help. What I wanted the NSR50 forks for was to mount disc brakes on a ZB50 (U.S. version of Monkey R). This is why I need ed the hub too.
Last night I ended up buying the whole bike instead of building one from parts. Here it is:

However, I will need some other parts from Japan for this bike like an exhaust. Have you ever heard of M Racing exhausts? I hink they are custom made.
Thanks,
