Umm you kinda have this mixed up......All the Japanease bikes use 108mm mount spacing, even if you have Brembo calipers like I do on a jap bike its 108mm spacing....100mm are used on European bikes like Ducati and BMW's etc, those will not fit on any of the hand brake brackets I have seen on the market as of yet...Everyone seems to be using the 108mm mount

All the 108mm calipers have the same offset from mouting bolts centres to the center of the rotors, but they have different offset from top to bottom. Due to the different bikes having longer or shorter mounting posts on the fork bottoms......That is why some require spacers to be fit between the caliper and the fork bottoms...If you have a FTI bracket he supplies 2 sets of spacers and instructions on which ones are to be used with the calipers you have...

And as mentioned HONDA calipers are the best choice because they have the cheapest OEM pads...Usually half the price of Kawi or Suzuki

WRONG

ALL Radial Kawasaki Tokico or Nissin calipers have 4 pads per caliper

The Suzuki and Honda Tokico has only 2 pads per side

Sorry meant to say the 05 06 CBR600rr use two pads per caliper on nissin caliper. Dont know Kawis

thanks, i appreciate the info!! are gsxr and honda pads the same then? so i can get honda pads if i have gsxr calipers?

First of all you haven't said what year/model Honda vs GSXR calipers, but as far as I know the answer would still be no....No Honda pads that I know of fit any GSXR calipers....
