About This Product

Arlen Ness Rotator II 11.8-inch floating brake rotor for left-side mounting on Harley-Davidson. Stainless steel outer band and precision-machined inner hub let the braking surface centre itself between the pads. The friction ring is decoupled from the hub, so heat does not travel straight into the wheel bearings. It also keeps its shape through heavy braking cycles. Crisp lever feel. Sold individually.

Manufacturer part number: 300-051.
