I've got them on my '03 RK....its not really a reduce vibration but changes the vibration. At idle with the stock (6 year old) rubber the bars would shake back and forth about 1". Enough to make the mirrors almost dizzying. I switched to the poly bushings and its less shake but a little bit more vibration at idle, as in not as much movement in the bars but still a vibration.
At speed I didn't really notice any difference in the vibration but did feel a little more responsive. Again, I was replacing 6 year old rubber.

I changed them when I replaced the fork oil and handlebars. The vibration is slightly reduced even with the longer handlebars.
If you are messing with the handlebars or forks, replace them. They are cheap and will last longer. Otherwise, I would not bother...

I bought some when I installed the WildOne WO508 handlebar but they would not work with the 1.25-inch diameter bars. The handlebar cover would not properly seat.
Looking at the flimsy stock rubber bushings, the poly bushings are the way to go. I wish I could have used them.

NO reason they should have not worked, I used them alot along with the one piece sporty top clamp, but with some bikes you have to drill the top clamp hole deeper so the allen bolts will sit flush with the clamp. there is plenty of meat left in the top clamp. any bars with the wiring hole in the center should use one piece clamp. especially ape's
on bat wing fairings, you do need to do this mod, otherwise the radio will contact the bolt heads and CD will skip more than you like.
