For several years I have had rear crash bar bags on my 06 RKC and they would slip off to the side of the bar, even though they are snapped tight. This has really been a problem on the left one which holds a water bottle. This past weekend as I was shining my bike up and trying to come up with a way to hold the upper part of the bags in place without puting a screw through them into the bar I had a brainstorm. Two sided tape. A small strip on top of the bar and then wrap the bag flap around as normal and snap it down. Doesn't slide a bit. I am sure everyone else out there has figured this one out before me, but if not, it sure is a simple and non-damaging fix for an annoying problem.
