Frequently Asked Questions
What's the advantage of a floating rotor?
Floating design allows the rotor to move independently on the hub, keeping the braking surface better aligned with the caliper and reducing heat stress on the mounting system.
Is this rotor a direct bolt-on?
Verify your bike's center bore size (1.99") and rotor diameter (11.5") match before ordering. Counter-bored holes ensure proper hardware seating.
Can I use this rotor on a Twin Cam or Milwaukee-Eight?
This rotor fits V-twin bikes with a 1.99" bore. Check your OEM rotor specs to confirm compatibility with your specific model and year.
What's the difference between machined and polished finishes?
Machined has a satin appearance from the cutting process. Polished is buffed to a mirror shine. Both are stainless steel with the same braking performance.
