Frequently Asked Questions

Will this rotor fit my Harley or Indian from the 1984-1999 era?

Yes, if your bike uses an 11.5" front rotor with a 1.99" center bore. Check your owner's manual or existing rotor to confirm compatibility.

Can I use this rotor with sintered brake pads?

Yes. Harddrive rotors are compatible with all pad types, including sintered and organic compounds.

Why are these rotors drilled?

Drilling reduces weight, improves heat dissipation, and enhances braking performance in wet conditions by clearing water away from the friction surface.

Do I need new brake pads when I install this rotor?

It's recommended to replace pads when installing new rotors. Worn pads may not seat properly on the fresh rotor surface.

How much does this rotor weigh?

4.79 lbs per rotor, making it lighter than equivalent solid rotors due to the vented design.
