02 GSX-R 1000 Forks, can you fit 6 spot calipers?

[EFE 1230]

02 GSX-R 1000 Forks with 600 wheel & discs, do any of the 6 spot calipers fit this combo?

I just like the way the old 6 spot calipers bite when you grab a handful of brakes and was wondering if it's possible.

[crazymofo]

yes sure do, but 4 pot tl1000s/rgv calipers are better

cheers.joe.

Thanks Joe,

So will the ZX7 Kwaka ones go on? (90mm mountings from memory,they fit my SRAD600 forks)

I think the SRAD600 are the same as a TL, never gave a thought to changing them but the 600 isn't that heavy, got ZX7 6 spots on my EFE and they allow 2 finger braking no probs.

want something that doesn't need a lot of pressure to pull on as my wrist plays up a bit.

No the GSXR1000K1/2 used 6 pots as standard, however the mountings on these were 63mm? from memory. The 4 pots from the 750Y to K3 and 600K1 to K3 will also fit. The 4 pots give better braking than the 6 pots do, and most people racing the 1000K1/2 swapped them for 4 pots because of thic fact.

It has been fitted with the "better" 4 pots so is there a way to reduce the pressure needed to pull them on?

does having dual brake lines to the m/cyl change the effort needed or will a radial style m/cyl do anything?

[ozzy1100]

k1 k2 1000 had the 63 mm hole spaceing 6 spots
the only other bike with that spacing in the 6 spots is the gsx 1400 (lighter yellow tho)

To lighten the effort needed to squeeze the same brakes you need to get a slightly smaller master cyl than what you have now. Basic hydralics smaller cyl driving bigger ones less effort but more travel. Find out the diam of your current cyl then find something that will fit with a small a step down in size as you can find will reduce effort at a slight expence in travel. Go to small and leaver will get to close to bars to be comfortable.

If you cant find a cyl that is just a little smaller , go see a "good" brake mob and get them to shim down a cyl the same as you already have. They will make a liner for the body and turn down the piston. I had one done a long time ago for a non motorbike project cost me about $75 to have it done 7 years ago.

The Japanese home market ZRX400 2000 onwards also had the same 6 pots with 63mm spacings although the used an M8 fixing rathert han an M10X1.25 that the Suzuki used. I would be looking at changing the master cylinder for a more modern radial item. Failing that an aftermarket Brembo radial 19mm bore with an 18 ratio lever will give good power and good feel, a 16 ratio lever will give good power but more lever travel and a 20 ratio will give very good power but with much less feel. I run Brembo radials on all of my bikes and I can vouch for the quality both the cheaper forged model and the CNC type.

sorry 9 years ago , getting old lol

[crazymofo]

yes sorry about the bum steer about the six pots, didnt realise you were adapting older ones.

what master cylinder are you planning on or are running now?

cheers.joe.

[EFE 1230]

It's got a square GSXR one atm the angled style to suit clip ons, I would like to try a radial m/cyl to see what that does just have to decide how much to spend.

I've had 2 Busa's with 6-pot's.
They really are nothing special.

B-King has radials that are waaaaaay better.
Funny enough the B-King get a radial master cylinder too,that
the latest Busa doesnt, it might be more suitable to flat bar's
as many sportsbike mastercylinder are made for clip-on's and
can look a little odd when put flat (like my Busa's)
