HOW DOES IT WORK? outer and inner diameter of the disk have a non-round design that enables better radial expansion of the rotor under extreme heat conditions. Moreover piercing holes are replacd by edges specifically designed to grow brake pad regeneration process CHARACTERISTICS > BENEFITS more braking grip > highly reactive less weight > better handling high heat dissipation > stable power at all conditions Compatible with: - Aprilia: RS 125 -05_M, RS 125 06-10_M, RS 250 95-97_M, RS 250 98-_M, RSV 1000 -03_M, RSV 1000 04-_M, RSV 1000 R -03_M, SL 1000 Falco_M, Tuono 1000 -05_M, Tuono 1000 06-09_M, Tuono 125_M, Tuono 50_M
