Wheel / Hub Tech's ! What hubs fit our bikes?
 

I wanna build up some 17 motard wheels. I am trying to do this as cheap as I can.
The plan is to get a used set of hubs front/rear with used rotors and sproket. I will pay to get them re-spoked with the new 17" wheels that I am going to pick up.

The question is.... What other hubs fit our bikes? Spacing? Brakes? Axles? Etc?

I think newer KX stuff fits but I am not sure.

Thanks all
