Not sure. I think the gold calipers on the Repsols are the same as the black ones and there's the brown coloured calipers which are found on the C-ABS models all which could be the same for me
Only difference is the colour they were painted to match colour scheme of bike, they should all be tokico
+1 I think the difference is cosmetic. They all share the same pads, have the same piston size and mounting points
