Man I was enjoying a great ride day and I look to my left mirror and its gone.Bummer It seems like a stick on.Any tips on where to get em in the USA.I have a feeling its a common part but if its Ducati specific lemme knoe.Thanks,Glenn

These mirrors are not as common as it maybe looks.
there are two or three different types ( however the differences are small)

On Ebay they are offered regular.
Maybe it's sensible to use selflocking nuts next time.

Good luck searching a replacement.

Let me ask, when you say your mirror fell off, do you mean the entire mirror, or just the piece of glass. The glass coming off is pretty common. When I say the whole assembly, I mean the blinker, mirror etc. Or just the rear view with the small ball joint to allow for adjustability which is mounted by a single screw, or just the round piece of glass, you still have the piece with the ball joint on it. Ani I haven't noticed any differences between the mirrors on my 87 paso 750 and the ones on my 93 907ie. They are identical, they even use the same mounting plate. Although the two bikes are completely different colors of red. Next to eachother the 750 looks orange in comparison to the deep red of the 907. That's the only difference I've noticed.
