I purchased 2000 and newer front fork legs to update the front brakes from the single piston to the mroe modern 4 piston. Do I need to replace the entire wheel, axle, and rotor to make this happen? Or do I just need to upgrade to a prettier rotor that fits my stock wheel?

 

I changed mine for the newer legs last winter. On the WG everything fit. Just make sure and use new bushings and seals.
