Following up with a little more info on this. After sifting through the brake parts catalogs I found that there are different rear pads for ABS and non-ABS models. Galfer #FD103 series matches up with the OEM rear pad I have and is listed for use with the 2012 NC700X in the applications/compatibility table on page 14. Part #FD134 is listed for models with ABS on p. 18.
Cycle Gear Rear Brake aftermarket options:
W/O ABS: Galfer #FD103 series or EBC #F140 series
With ABS: Galfer #FD134 series or EBC #FA174 series
Bedtime reading: (Both catalogs include full scale outlines of the pad size/shape and application info)
