I have had these on my bike now for a few months with a new pair of BStones. So far so good. They seem to work but it will take time to really find out what they can do. At slow speeds you can tell ya got something going on .. until things get balanced correctly. So dont expect a silky smooth ride 100% of the time. But on the highway where a Gold Wing is meant to be... they do what they claim. Nothing perfect in this world ... but if they can save the rubber ... they will be worth it... good luck.
