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: - Triumph: Bonneville_M, Scrambler 900_M, Speed Triple 1050 11-_M, Sprint RS 955_M, Sprint ST 1050_M, Sprint ST 955_M, Thruxton 900_M, Tiger 1050 07-_M
