You can only buy the Ducati box from Ducati themselves, Givi do make them, but do not sell them outside of Duke dealers. You would need to find a different box that will fit and use a Givi key.
Sorry I should have explained myself a little better, I was after the model number as I want to get a givi inner top box bag.
Top case for the 1200/1260 Mutley is 96780692A. However, I doubt that Givi themselves would recognise this. It's a 48 litre case and I guess based on the Givi V47. There are 3rd party inner cases from the likes of eBay that are pretty good and much cheaper. I have one of these and have been using it for four years without issue.
