Stainless steel fully floating Brake RotorsOuter Brake Ring features machined and painted Rotor slotsInnovative design improves brake performance and helps cool the rotor faster during extreme useDesign gives maximum resistance to fade/warp from heat and mechanical stressesRotor design allows for better heat exchangeRotor bobbins are stainless steel for efficient rotor ''float'' so the rotor will not warp and distort under extreme stress/heatStainless steel outer rotor rings are machined and the surfaces finished using a bi-lateral cross-textured grinding process that keeps rotor runout to no more than 0,01mmRotor weight and inertia are not increased compared to other brake rotor disc types do not impede the motorcycle's steering/handling characteristicsVery original style, great for customizers or to enhance the look on older stock bikesManufactured in Europe to ISO/TS 16949 certified standards that meet or exceed OEM specifications
