Well, I went for the DP version in the end. OK it was the most expensive, but I was keen to keep it Ducati, and when I popped into Ducati Aylesbury on Saturday they had one in stock!
Funnily enough though, when I said I was after a tail tidy they said "Yes, we usually offer two brands, R&G and Evotech"! "What about the Ducati one?" I said
. Maybe they don't sell many due to being twice the price...
