Hayabusa 6 piston on stock Sh forks
 

Does anyone know if the gen 1 Hayabusa 6 piston tokico callipers are a direct bolt on to the standard Sh forks? are they the same bolt centre distance as the 01-02 gsxr1k 6 Pistons?

I'm gonna say no, but but I'm not promissing. You can check on Partzilla or another parts site to determine if it's the same caliper assembly, but if not, that doesn't necessarily mean the bolt spacing is different. I haven't researched this in a while, but my memory says only the 01-02 GSXR 1k are direct bolt-ons.

So, I checked Partzilla and GSXR 1k calipers are only used on the 01-02 gixxer. I have these calipers for my SH and I remember researching before getting them, but I don't remember if these were the only direct bolt-on 6-pistons or if I couldn't determine if any others were bolt-on.

Why are you asking? Got a good deal on some from a Hayabusa? F4i calipers are a better performance upgrade from what everyone says. The 6-piston calipers look cool, which is my main criteria for any mod. Of course.

Im on my 4th caliper swap.... I did try the GSXR 6 piston, and did not feel the were the best option for feel and power at the disk. I ended at the Nissan F4i calipers and Brembo Radial MC
My notes say the 2001-2002 GSXR calipers fit..... not that they are the only ones they do

I remember k1 GSXR1ks have rubbish brakes.

Cool looking rubbish brakes.
