I have ordered Honda parts to do my rears on my 2010 (same as 2011). I can't remember if I posted the parts or saved the info anywhere though.
I'd probably go about looking up crossovers on the rear pads, and then draw the assumption that the calipers and carrier pins are probably the same.. They will have been used on Suzuki DR's, Yamaha WRF, Honda CR/F etc..
This shoud.. (not confirmed).. work:
