Mid-USA Drilled 11-1/2 Inch Brake Rotor Fits Harley-Davidson 1984-2017
A drilled rotor that helps the brake keep its bite in the rain and under repeated hard stops, with a bright face that dresses up the wheel on a stock bike or a custom build. The drilling clears water and heat from the pad contact area, and the ground face gives even, pulse-free braking at the lever or the pedal. Pick the front or rear position and bolt it on.
Key Features
- Drilled face disperses water and heat and trims rotor weight, so the pads keep their bite in wet weather and under repeated hard stops
- Precision ground for maximum flatness, so there is no pulsing through the lever or pedal from an uneven rotor face
- Included adapter ring reduces the center bore from 2.220 inches to 2 inches, so one rotor installs on 1984-1999 hubs with the ring and on 2000-2017 hubs without it
- 420 stainless steel with a low carbon content under a full polish keeps its shine instead of dulling with use
- DOT approved, so it is built to a street standard rather than as a show-only part
- Offered in a front version drilled for 5/16 inch mount bolts and a rear version drilled for 3/8 inch mount bolts, so the rotor matches the hardware for its position
