Congrats! That looks great! I had a Bagster setup on two different bikes, and loved it on both. It's top-shelf stuff, for sure.
I debated doing the same on my '14, but I've since accumulated a couple of the tankring-style bags from SW Motech, and thought I'd better just stay with them. But, man, yours makes me question my decision. It IS possible to use both, after all... What a great-looking cover!
Edit: just saw your post about maybe using a tankring-style setup. They're fantastic, and super handy. One thing I did find - and this was with SW Motech's old-style of tankring, on a BMW GS - the bag can be tough to snap down onto the ring using the Bagster with it. I ended up shimming up the ring somehow that I don't quite recall (small washers under the tank bolts, maybe?) which solved the issue on that particular setup.
Lastly, with the MV riser plate, the "City" bag works well. Midsize bag, but it has a narrow-enough front that the bars just touch it at full lock, but don't impinge movement.
