Title: Thread size for the mirrors?
Post by: Mikep328 on August 01, 2025, 07:29:38 PM

Hi all, I installed the new handlebar mirrors today and want to "plug" the holes where the OEM mirrors screwed in.  Anybody know the thread size?

M10 x 1.25 on mine

Find a spare M8 x 1.25 bolt and compare thread pitch with the old  mirror by interlocking the threads side by side.

Regards
Dave

On mine I plugged the holes with rubber hole plugs, the slightly domed ones. They're just a push fit and have never moved.
