The BRAKING WK042R SK2 Directional Rotor Right is a high-performance motorcycle brake rotor engineered for select Buell applications. Developed as the second generation of BRAKING’s proven SK design, the WK series combines a directional carrier, an updated outer-ring profile, and a directional seat set at a 14-degree angle. The result is a lightweight, application-specific rotor designed to deliver consistent braking performance and dependable control.
Manufacturer Part Number: WK042R

The directional carrier is approximately 9% lighter than the previous-generation design, helping reduce unsprung and rotating mass while maintaining the durability expected from a performance brake component. BRAKING developed the WK series outer-ring profile in cooperation with leading racing teams, and this version uses the appropriate high- or low-profile configuration for its intended motorcycle application.
This right-side rotor fits 1998–2002 Buell M2 Cyclone and 1998–2002 Buell S1 Lightning models. Verify the motorcycle year, model, mounting position, and existing brake configuration before installation. The BRAKING WK042R is intended as a direct application-specific replacement for the listed fitments and should be installed according to the motorcycle manufacturer’s service procedures.
