I used the KTM tank bag for two seasons and while I never really found it was in the way when standing (and I am up on the pegs the second the pavement runs out), I did find that I could never get the thing to hold on tight enough and it always seemed to be shifting from one side to the other. The other thing that annoyed me about it was far from water tight. Not an issue when riding but when parked the stuff inside would get wet. Of course, I never had the silly shower cap when I needed it.
This year I've traded up to the Enduristan Sandstorm. I haven't left it out in the rain yet (it is supposed to be waterproof) but I can tell you now that it holds on tight!
