Title: Minimum rotor thickness
Post by: 05Quadrasteer on August 04, 2020, 12:45:57 PM
Does anyone know what the minimum rotor thickness is for a 2015 Road Glide Ultra CVO?  Looking for both the front and rear rotor minimum thickness.  Not having any issues but coming up on 150,000 miles on the bike and thought I should check the thickness but of course need to know what the minimums are so a decision can be made if I need to replace my rotors.

G’day 05Quadras,

The minimal acceptable thickness is stamped on the side of the rotor as per the manual. On Lucille 15 SERGU it SAYS 4.5 MM. note these have been changed out under warranty as the originals rusted up.

Cheers Tom

Thank you for the information.  Now I just need to find my micrometers and measure them.

Sorry for the hijack!

Has anyone resurfaced rotors or just replace them?

My fronts on my '09 SERG have been a bit jerky (warped) since very early on in its life.  Here in the Black Hills for a couple weeks and using my front brake does tends to create a bit of a shudder when slowing down.  Rear seems just fine.

Many bike rotors are stainless Dan so you wouldn't "turn" them on a brake lathe even if they weren't so thin to begin with.  They'd warp like the shimmy in my butt when I'm doing my happy dance.  They'd have to be ground true to keep them flat.  Even though rotors (compared to far more substantial car parts) are often surprisingly expensive they've become throw away items if they have a problem.
