R1 Premier Series - Slotted Rotors

R1 Premier Series takes braking to the next level. The R1 Premier Series rotors provides the ultimate stopping power needed for demanding driving and harsh conditions. Made for those seeking the highest quality, reliability, and longevity in a brake rotor without a complete brake overhaul of a big brake kit.

Manufactured using more Carbon, Chromium, and Molybdenum, these High Carbon Alloy rotors offer increased braking performance and strength. A center split core casting provides greater stability. Black Electro Coating protects against rust while extending rotor life. Mill balancing and double disc grinding reduces thickness variations for smoother stopping, minimal vibration, and improved break-in. All R1 Premier Series rotors are designed for direct fitment: no modifications are required.

Diamond Slot Technology™ offers more benefits than round slotted rotors. Diamond Slotting removes brake and road debris and prevent pad glazing, extending the life of the pad and the rotor. The Diamond Slot tipped ends provide an indicator for rotor replacement. When the tips are gone, rotor replacement is necessary. 365 Days Manufacturer Replacement Warranty against warping.
