The "breakaway" mirror was designed so that in a crash where rider went forward, the mirror would rotate "forward" somewhat too, for safety.
Yamahas used to have a left mirror with left hand thread, and a right mirror with right hand threads - exact "mirror-images" of each other. Sorry.
So to cut the number of mirror parts in half, manufacturers went to reversible mirrors, like on the CB1100. As Suhawk 305 says, left and right mirrors and parts are identical, just rotate the mirror head on the shaft 180.
The threads on the mirror itself are left-hand. The threads on the bike in both master cylinders are right-hand. They need an adapter with right-hand male threads to screw into them, but a left-hand female thread, with a left-hand lock nut, that the mirror screws into.
Snug the adapter onto the bike, thread the nut up the mirror, thread the mirror into the adapter most of the way, and snug the lock nut in to set the mirror angle. The mirror should "break away" in either direction if the adapter or jam nut are not over-tightened. If overly tight, pushing either mirror will cause it to tighten one thread and /or loosen the other.
I see your point PK, Good clarification.
