Rotors are a hot touch to my R1 and fit perfect in place of stock. They arrived in a reasonable time and," just my luck", went on sale the week after I bought them!
Break in period: All brake pads must be bedded-in with the rotor they will be used against to maximize brake performance. The bedding-in process involves a gradual build up of heat in the rotors and pad compound. This process will lay down a thin layer of transfer film on to the rotor surface. Following the bed-in procedures provided by the manufacturer will assure a smooth, even layer of transfer film on the rotor and will minimize brake judder.
