I have the 2016 model and have not really seen a good tank bag that has straps in a horizontal direction that would work well. Because I wanted just a small bag with a map case on the top I went with a bag with suction cups. I only use the fore/aft cups, leaving the L/R side cups tucked under the bag as they won't stick to the black plastic parts that they reach. If you can find a model with D-rings in the corners then you can add a couple of 1" straps to run through them and the rails and then put on QR buckles. I'll probably do that at some point but the bag is held pretty securely with just the 2 cups (they're probably 2.5" cups, not the little quarter sized versions). I did a 700 mile ride and a 350 ride and the bag stayed exactly where I put it. That being said it is closer to my gut which requires me to look further down when I need to do a map/directions check. If/when I get some decent straps/buckles I'll probably be able to mount it closer to the front and just use the aft suction cup.
