My RT had chrome mirrors from the CL(I think)added in addition to the fairing mirrors. Besides being chrome, and looking hideous(IMHO - they are for sale)so I took them off. I saw a K bike with a mount that seemed to go through the same holes where these chrome mirrors had been. Nice and neat and it seemed it could be for my Escort Solo and my GPS.
