Do the Centramatic balance rs seem to work real well on the Can Am Spyders? I did use them on my last two Goldwings and they seem to help tire cupping. I just placed an order for a set for my 2015 RT with Lamont, Lamonster Garage. I have had my front tires balanced a while back and I know it sure helped. As soon as I get them I will install them on my front wheels and in a short time I will be putting a General tire on the rear and at that time I will install the Centramatic balance on the rear. When I purchase the 2015 Spyder in July it had 10,000 miles on it and now have 17,500 miles on it. The front tires I knew were out of balance and I had them balanced and after that it has always rode pretty smooth. I installed Doc's belt vibration damper which I am sure helps and I did my own laser alignment, which it is probably not perfect and now with the Centramatic balance rs should make it pretty good for touring. I do most all highway riding around 70 to 80 mile an hour. I live in Iowa so I haven't rode any since early December.
