Upgrade your V-twin's braking system with the Harddrive Stainless Steel Floating Brake Rotor. Measuring 11.5 inches in diameter with a 2.22-inch center bore, this machined-finish rotor is engineered for superior stopping power. Its floating design significantly reduces rotor deflection and improves pad contact for consistent, reliable performance.
Why riders pick this
- Stainless steel for enhanced durability
- Floating design improves pad contact and reduces deflection
- Machined finish for a clean look
- 11.5-inch diameter, 2.22-inch center bore
Consistent and powerful braking is paramount for any rider, and this Harddrive floating rotor delivers. By allowing the rotor to slightly self-center during braking, it ensures that your brake pads make full, even contact across the friction surface. This not only enhances stopping power but also contributes to longer pad and rotor life by minimizing hot spots and uneven wear.

- Constructed from high-grade stainless steel for durability
- Floating design minimizes deflection for improved pad contact
- Sleek machined finish complements any V-twin aesthetic
- Counter-bored mounting holes for a precise, secure fit
