Me. I have it on my brand new 1260. Not as bad as that but still pissed me off. As per a recommendation i have covered it with clear 3m tape. 10cm x 100cm piece. Thoroughly cleaned it, applied it then cut out bits needed
There are a few threads covering this issue. This is the most recent: https://www.ducatiforum.co.uk/threads/boot-clothing-rub-to-engine-casing.82017/
Thanks guys. Guess I’ll just live with it. Shame because it really is noticeable and looks like pants!
