I bought some FAR Mirrors via Amazon. Needed to replace broken ones on the 748 which had indicators in them. Although it stated they were for a 916 when they arrived they weren't. It's possible they are nothing to do with Ducati Anybody got an idea what they might be for
They look more like non-OEM. FAR made mirrors for one of the MV Augusta models, and they had indicators in them, similar to the above.
These were the similar type of mirrors I had in mind although not quite exact, made by FAR and some people used to use them on Ducati's as they had the same pin and bolt fitting.
