Gsxr 1000 k3/4 forks, what r6 calipers fit

R6 calipers are a monoblock construction so generally considered better than the radial gsxrs (if you could notice the difference is debatable). I have r6 callipers on my gsxr1000k4 and they are excellent, with brembo pads, disks and RCS master cylinder stopping is like getting hit in the face with a spade. I have got myself a set of k4 forks for my TLS project and ended up with k3 calipers cause they were cheap and I was only going to ride the to on the road. K3 calipers have 4 pads per caliper while the k4 has two pads per caliper, k3 pads seem to be more expensiuve , performance wise never ridden them back to back to compare. Anything you get will be miles better than the rubbish from the factory!! ☺
Cheers
Forgot to say any year radial r6 or r1 caliper will fit other than the later 6 pot r1 calipers.
