the kawi line up makes it to easy... figure out what size rotor you want 300/310/320 and go for from there.. the 330mm from the 16+ is not a very good idea, as calipers do not fit with the oem wheel so easy.
This was the route I went and it worked great.The ZX6R Nissins work great on my ‘05, direct bolt on. I also did lines, pads, Brembo MC and Braking rotors. Did the trick.
