how thick of a rotor can you stuff in a stock caliper(front)? :headscrat
my stock rotor is just over 2mm, my aftermarket rotor is close to 4mm thick.
will i run in to any problems like premature wear of pads or rotor? or will the hydrolic system take up the differance?

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.

At 2mm your stock rotor is probably wore out. Most dirt bikes come with 3mm rotors with a wear limit of 2.5mm.

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.

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.

Flat, smooth concrete. Only had to remove a couple 1/10's of a millimeter to make them work properly. Figure-8 them on the cement, and that did the trick.
