Frequently Asked Questions

What's the difference between floating and fixed rotors?

Floating rotors have a center carrier that moves slightly to center the friction surface under braking, reducing deflection and improving pad contact for more consistent stopping power.

Is this rotor machined or polished?

This part comes in a machined finish. Harddrive also offers polished versions under a different part number.

Will this fit my Harley or Indian?

Yes — if your bike uses an 11.5-inch floating rotor with a 2.22-inch center bore. Check your owner's manual or current rotor to confirm the size and bore diameter.

What's included with the rotor?

The floating brake rotor only. Mounting hardware, spacers, and brake pads are sold separately.

Can I use this on the front and rear?

This is a single rotor. Front and rear may require different sizes — measure your existing rotors or consult your bike's service manual.
