I have a set of front Calipers and Rotors from a 2003 or 2004 R6. These will likely fit alot of other things, I'm not up on modern sportbikes.
These are in excellent condition. I can get a bunch of measurements for you if you need them.

I'm in the midst of a front brake upgrade on my 83 Kawi 550. I purchased a set of rotors and calipers based on the rotor fitting on my front wheel. I ended up getting a set of the 03-04 r6 rotors and calipers. The calipers are the 4 piston 'blue dot' calipers used on a bunch of Yamahas.
