Just fitted this Brembo rear caliper on to my 1125r. This is the caliper detail: Brembo P2.32F rear brake caliper black 84mm. Fits straight on with minimal fuss & works a treat.
If anyone is thinking of doing this make sure you get the caliper with both Bleed & banjo at the top otherwise it will be more difficult to do as you have to twist the brake line to line up the Banjo.
I did put a washer spacer between the caliper mount & frame but it isn't necessary and next time I take it off I will remove these.
Believe me when I say it transforms the rear braking which as standard is pretty shite.
Hope this helps someone.

Forgot to say that the rear replacement pads for the Brembo are £13 which makes changing the caliper worth it as Buell rear pads are £45.
