I got my Geza cover (Size: Medium) a few weeks ago. (Link).

Well, now that I'll be putting the Givi 3 bag system on my bike, it would no longer fit with the bags in place. So, they offered to let me trade up to the Large size, which will cover the bike and the bags, just by paying the $20 difference in cost.

Just wanted to point out that the cover is great quality (the little that I've used it :D), and company is VERY nice to work with.
