Ducati Performance used to offer these for SBK's. The last pair we managed to get was over a year ago off of a closeout list from Ducati. Part number is 97061SAAA and they show as "not available".. You might check with other dealers, some may have them on the shelf still. good luck.
Thanks Brian! I was looking at Ebay.it but didn't think to check the local EBay. Too bad the guy has the price way out of line, that is actually more than buying them in Italy, shipping them here and playing Italian VAT!
I had a pair of those on my 996, paid a ridiculously high price for them because they were still in the original packaging. They only work at full extension, and they really don't look very good in that configuration. I was also unhappy with the size of the mirrors, pretty small if good visibility is your goal. I sold mine for $250 on eBay, and still took a beating. To each his own, but I would try something different.
