Well I've owned my 2010 GL1800 for 13 or so months now and I've put on 12,800 miles weekends only and wore out the stock Dunlop tires whereby I have put two new Dunlop Elite III on the day before yesterday. When I had the tire put onto the rims at the dealership I asked them to NOT balance either the front or the rears. I then took it out on its first run hoping these Centramatics worked as I was told they would. They work absolutely perfectly and the bike is as smooth as it can get. These are well worth the price and I now know as I begin to wear these tires in and rubber is removed from varous areas of the front and back tire my tires will always be perfectly in balance making for a smooth ride until the next pair go on about a years from now. I would suggest this product to all Goldwings and if they work for the other bikes as well as they did for me I'd adbise them to buy them now. I only wish I has a set to try on my 2012 Honda Civic EX commute vehicle. Wink Wink !!
