I've contacted SWM when I first got the bike in June. As far as what they told me, this tankbag is not 'quicklock', what your friend has as shown in the pic is the usual strap/tie-down system. Quicklock has a ring mount right on the tank cap, and the tankbag would have the male/female mount to snap into the ring on the tank cap, so the tank bag would not even touch the tank. I have two on my old BMWs, and yes they are a great system and the quality of the bag is better than stock BMWs IMHO. But the system doesn't work on Tenere because a) they don't have the ring that fits the new 5-screws system on the new Tenere, and b) position of the ignition key hole would be in the way of the tankbag. It's really a shame.

Personally, because of the short tank area and the position of the ignition key that makes it hard to find a proper tankbag, I find it claustrophobic to mount any tankbag which inevitably gets into the front part of the seat area. I had a Held square-shaped tankbag which I thought its shape and size would fit well enough to the Tenere and I rode with it for 7000km, but I just find it obtrusive optically and limits my movements of standing up/sitting down.
