Exactly my thoughts on tank bags. There’s a couple of the lads who come on our annual trips have them. They have to take them off and carry them about whenever we stop for a wander around or park the bikes out of sight. I certainly couldn’t be bothered with having to carry a handbag around. Everything i need to hand is in my pockets.None of them, they're all a faff which is why i stopped using them.
If you do have to have one then a tanklock is probably the easiest.
