Hi Wasser
I ended up buying the Ducati inners, but I have since found out that a mate of mine brought the other ones for his 1200 Multistrada and they are fine their is also some other ones on ebay for about £50 ish and the seller is from the UK.
Surely your dealer can sort you a deal out with a set of panniers as you brought the bike from them, my Dealer seems to give you 10 percent off any Ducati accessories
