I'm running a radial master off of an 05/06 ZX6R/RR. The 07 and newer ZX6R are supposed to be even better. I did the front end swap, but kept the stock master with braided lines, and that gave me better stopping power. Swapped the master and got even better stopping power. I vote that you get a radial master from any Japanese sport bike and try that first before you explore calipers. I got my radial master for $50 shipped (from here on the forum), plus another $55 for Goodridge lines off of ebay. Your stock lines won't work with a radial master cylinder. Pretty much all sport bikes that I'm aware of run 7/8" bars, so any master can be made to fit and work on your bike. Good luck.
