86 GL1200A -- so i never get to use this as i purchased them for my wife who is always my passenger. She tells me she loves the added comfort. her problem was her hands would swell on long rides but now that she can easily rest her arms and hands higher she is enjoying it.. The benefit to me is i get a back rub more often when riding now and a happy wife is a happy life.
now for mounting. I'm not sure i really like the way they are designed to mount. single bolt mounting point which allows the rest to rock slightly. There are holes that match up to the hand grip that i could attach a u-bolt which would stop this but there is enough of a gap that I'm not sure i want to do this. I'm waiting to see if the bolt loosens at all over time and if it does then a solution will have to be made.
As for the product i wish the tension bolt that allows the arms to tilt out and in was a hand tension bolt that could be adjusted without having to get out the wrenches...
other than that i would say i love this add-on..
