Ducati have had an issue with all 937/950 Supersport mirror vibrations making them unusable at anything over 40mph. I don't know if this affects other models but decided to post a possible solution here which I'm trying. Ducati issued a mirror recall to update the stem mounting plate on the fairing where they attach (reinforced mounting plate) but reports back suggest this hasn't cured the issue.
It appears that the oem rubberised strip running around the inside of the mirror casings don't make contact with the mirrors (as obviously when you adjust them there's daylight between those strips and the mirror glass). This renders the glass to be undamped, and as they're centrally mounted on a knuckle, vibes from the engine pass up through the fairing and are transmitted along the plastic stems to the mirror/indicator casing.
I found, lost in the small print on t'interweb how these were intended to be adjusted....you get them adjusted for best view then rotate the right mirror anticlockwise at opposing diagonal corners until the glass edges touch the rubber surrounds, and do the same (but clockwise) on the LHM. It works, but not for long as they get shaken off this contact point. I decided to cut some small strips of D section of silicon rubber draught excluder, double it up and wedge it into the larger gaps neatly. This has had the effect of holding the mirrors much firmer in place (they seem quite solid now) and retained at the contact points whilst improving damping. We'll see if it has doe the trick as I have a pre-exam test ride for my Tutor quali on Friday with RoSPA and working mirrors will be a must!
