I have felt a slight low speed rub before but today it was confirmed by Ducati Ashford mine are fairly warped. I never told him , he told me and am very glad for that
He said a few models have been suffering including 1100s ( not sure about 1100 as they use different heavier centres but he said 1098/1198 too. Think its just a bad batch. Maybe a good idea to check whilst still under your warranty.
