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: - Honda: CBF 500 04-06_M, CBF 600 -07_M, CBF 600 08-_M, Hornet 600 07-10_M, Hornet 600 11-_M
