When paying a visit to my dealer last week to have the long overdue heated grips fitted (just in time, given the cold weather), I mentioned that there were a couple of small cracks in the screen around one of the mounting points. The service manager immediately took a pic and said that he would get a claim in for a new screen but would I want another standard one or the smoke-tint touring screen? Tinted screen!...yes please. I've just had it put on and it is good. Same shape as the standard one but about 2 inches taller, which suits me fine as I'm over 6 foot tall.
The mechanic who fitted it said that he's had to replace several showing the same fault, so take a look around your mounting points and, if there is a problem, Ducati will replace.
