This is the bag I put on my new Stelvio. I like the quality and features of the bag, but check the size as a camera and water bottle might be tight, depending on what you use.
On my V85 I have the Giant Loop Diablo, which is a little bigger. Two things to be careful of on this bag are; the map case needs a cover since it isn't really too waterproof. The second is that the bag is so much longer it makes getting the ignition key access a little bit of a pain. All in all it is a good quality bag.
