wear limit on my bike is 2.00 mm im at about 2.5mm definetly not claped out yet still stops fast with good bite.PowerFiend said:At 2mm your stock rotor is probably wore out. Most dirt bikes come with 3mm rotors with a wear limit of 2.5mm.
i have a stock nissin caliper. what did you shave the pads with to get them even/flat? will post pics soon 17s just arrived. but gotta finish rebuild stearing stem berrings and fork freshen up.SlowSlide said:Modern sportbike rotors are usually 4.5mm thick. I'd bet our moto brakes are real similar. Don't know what kind of caliper you have, but I suppose you're right that the hydraulics would compensate. Use an old pad backplate, and a C-clamp to push the piston all the way in the caliper, then put your pads in and try. I've raced a superbike, where we had to shave just a little thickness off the pads so they would fit, and not drag. Other than that, they worked fine.
