Not sure what you're trying to do here.... Gen2 ??I've done a R1 fork conversion on a Gen1 with 5PW bottom yoke + 2D1 (FZ1) top yoke.
Centre-to-centre for the forks on the early R1's is 210mm. Same for YZF750, Fazer1000, FZ1, and FZ8.I think the TRX850 and FZR750/1000 is 200mm. Later model FZR's (with USD forks) were 210mm.Not 100% sure on that though. Better to double check.
