"....all things being equal, rotors usually warp due to excessive heat. That would be caused by the brake pads dragging."
Grump-
I replied in the other thred too, but another factor is the type of material used to make the brake pads. Judging by the incredible mileage that has been reported on the Triumph brakes, I think that's the likely source of the problem. In road racing, ceramic pads are notorious for warping rotors, due to the excessive heat buildup.....
