Hi Troy, that caliper bolt hole centres for my B model 9 are 62mm. What do you mean exactly when you say "depth of the calipers"? If you like, I can try to fit one of the calipers off my 9 to my H2 tonight to see if it fits? I assume the forks are the same as the H1.

[captain slow]

the depth would be from face of bolt hole to the face of outside brake pad fully open .if u could see if calipers can be swap that would be great for sum reason iam getting brake faid no matter what i do change fluid rebuilt caliper srud pad face etc so next step swap calipers cheers troy

[Kev]

No worries, I'll check it out tonight for you. What master cylinder are you running?

I'm not sure if you are allowed to use a radial in P6, might need to check out the MOM's.

[steve086]

nah not allowed the radial mastercyclinder for p6

[Kev]

Just checked. 16.6.6.1 Radial brakes are prohibited. It doesn't refer to calipers or master cylinders though.

[Kev]

Thanks Steve. Maybe I should have checked the post before hitting submit.

They're a perfect fit Troy. FWIW though, I'm actually steering away from the Tokico callipers on both my 9 and H2 and going with Nissin. I'm looking at buying a set off an early GSXR but I will need to make some adapters so they fit, which shouldn't be too much of a problem. From what I have been reading, they are a shit load better than the Tokico calipers of that era. I just need to find a decent M/C to go with them on the H2 that's period legal.

This is the type of calliper I'm referring too.

[captain slow]

thanks for that kev i would think that the tokico calipr of the zx9 would be better than the ones of the zxrh1and h2 .the m/c as far as i can tell is fine for know ,if you are going to run nissan caliprs from a gsx i would use the m/c off the same bike .as far a radial m/c in p6 there life will be short lived for they will be cracking down on that sorta thing by the way what year is the b model zx9 cheers troy

[Kev]

No worries, I'll keep it in mind. My ZX9 is a 1995 model (B2), which was the last ZX9 to use the 4 pot Tokicio's I believe.

[Kwak addict]

ZXR J & L & ZX9 B1 & half of B2 used calipers with 62mm Bolt Hole Centres, ZX7, ZX9 B2 1/2, B3, C & E had 90mm BHS. GSXR 1000 K1 & K2 Tokico 6 pots are 62mm BHS. Heaps of bikes used the 90mm BHS so there's a lot of choice of calipers in Toki or Nissin.
I find a 14mm bore M'cyl. works best (actual stopping power as well as lever feel/effort) with 4 pots & 5/8 for 6 pots.
H.T.H.

[captain slow]

thanks for the extra info kwak addict cheers troy
