back brakes 03 cbr 600rr
 

I bought an '03 CBR 600RR about two weeks ago and I'm really pleased with it. The only thing i dont like about it is that the back brake rotor looks like it is off a CRF 150 and doesnt match the feel of the front brakes. Is it common to put an oversized back rotor on? where could i buy one?

the rear brake caliper provides a fourth of the stopping power for the bike, the front provide the other 3/4. To put an oversized rotor, you would need to find new caliper brackets to accommodate the rotor. My advice is to get better pads(HH EBC Pads) and a nicer rotor thats race ready to provide more bite.
