Will the footpeg rearset from a 94 fit a 2001? That's the one that is about 18 in long w/both pegs, the brake lever and the mount for low pipes.
I don't know for certain, but unless the 01 is an S4 the 2 bikes share the same 851/888 based frame.
I think it will.
they're the exact same parts (even if it were an S4) ;)
