Braking floating 9-spoke Wave brake rotor 11.5", rear

Floating brake rotors with approval. Speedo gap is present in front brake rotors. Counterbored mounting holes, 56mm ID for 00-up models. The wave design allows the rotor to have certain deformations during heating and has a perfect heat disposal. The rotor is therefore very resistant to high temperatures. Polished finish.
- 11.5" / 292mm O.D.
- 56.3mm I.D.
- 10.2mm (3/8") counterbored mounting holes.
- Mount style 'B'.
Note: For XL Sportster models, where the rear brake disc is mounted on the left side of the wheel, Big Twin rotors will fit. However, a non-symmetrical brake disc pattern will, visually only, not match the front brake rotors.
Note: Check your local MCS dealer or the MCS sales department for exact type of approval and validity on bike model and years on the test report.
