I obtained a pair of 1290 Duke mirrors to replace the original ones on my 2018 Duke 390
Sadly it seems the RHS mirror mount is a reverse thread and the 1290 Duke mirror is not.
Is there an adapter l can use? The 1290 mirrors look great on the bike, much better than the OE ones in my opinion.
I tried the Puig mirrors and they looked great but were too small, you couldn’t see hardly anything through them.
But they came with adaptors for the reverse thread on the RHS
And a LHS one to make it the same height.
Why would you use a reverse thread? I can’t see any reason for it, except to make it difficult for aftermarket mirror manufacturers
