ARLEN NESS Spider Rotor - 11.8" - Blue 300-061

If you're running a Harley and want braking performance that matches your engine's power, the Arlen Ness Spider Rotor delivers the stopping force and visual presence your bike demands. The floating rotor design reduces heat buildup during aggressive riding, while the lightweight billet carrier keeps unsprung weight to a minimum—critical for maintaining suspension responsiveness and ride quality. Built from high carbon 420 stainless steel with titanium hardware, this rotor is engineered to handle repeated hard braking without fade or warping.
