Gixxer Calipers

[Legman]

I have got onto a set of GSXR 1000 K4 Tokico Calipers in mint condition for $80.00. They are gold, very similar colour to the Nissins. They look identical to the black K5/K6 calipers.

My question is: does any body know if they are a straight swap for the Nissins, as the K5/K6 calipers are?

Also, is the Gixxer master cyl. 16mm.?

Thanks in advance for your help.

Not sure what the K4 master is but the radial MC from the K5/K6 - is a 3/4".
Check the GSXR fork swap thread and look for post with pictures by Racecomp that illustrates the the difference between K4 & K6 calipers. The K4 utilizes a 300mm rotor while the K6 is 310mm.
If as reported elsewhere the K6 calipers centre up the caliper in the 320mm rotors on the Triumph, it would suggest a spacer would be required to utilize the K4 calipers.
The ideal replacement (most straight forward) would be the K6 radial MC & calipers.
