Aftermarket rear rotor?
« on: July 21, 2020, 10:34:39 PM »

My warped rear rotor is getting bad, does anyone know of an aftermarket 240mm rotor that fit a 2016 Zero DSR? The OEM part is 25-08170

I'm finding some online but can't verify if they fit

Searching for cross compatible motorcycle parts can be a challenge.

I would suggest you gather the specifications of the rotor: Outside diameter, width of the braking surface, bolt pattern, bolt spacing and hub diameter.
Create a drawing or CAD with this information for easy reference.
Once you have that data check manufactures webpages like EBC or Galfer. They likely have catalogs online that will list these measurements.

In my searches for compatible parts I have found that moto parts manufactures are very willing to help you find the part that will work.

Well, you can bet that Zero didn't make the rotor themselves but bought it from an outside supplier. The most logical source would be the manufacturer of their brake calipers, J.Juan. Perhaps they sell after-market rotors?

However, I will say that it might be easier and relatively inexpensive to purchase the rotor directly from Zero. In my experience, their chassis parts are priced a lot more reasonably than parts that you can purchase from any of the major Japanese or European brands. (BMW and Triumph come to mind.)
