I brought my tire to a dealer who told me that you only have to balance the front wheel, not the rear, does anybody disagree with this opinion?
I had a similar experience with local shops a couple of years ago. As a result, I've changed my last three tires myself. I balance them using a nice little pocket balancer made and sold by Marc Parnes (google Parnes tire balancer). Parnes sells adapters for the Triumph SSSA wheels. A bonus is that you can buy adapters for almost any bike to work with the Parnes balancer. I use mine to balance the tires on my BMW as well. To make your money for the balancer back, you have to change your tires yourself, but if you didn't want to do that and couldn't find a shop to balance the SSSA wheel, you could always have a shop mount the tire and balance it yourself.
I have a VFR. The Honda dealers around here don't balance them either. I mount/balance my own tires but I take the rear to a local auto tire shop to spin balance it. Usually do it for free or a couple of bucks. Alot cheaper than the $100 for the new cones/shaft for my balancer.Try a Honda dealer. The VFR is single sided and they should be able to balance that so technically the S3 too.
Go to cyclegear.com for store locations. I found one in your state:Whats a cyclegear store? Seriously, I'm about 1,000,000 miles from nowhere. I'm 150 miles from the nearest Triumph dealer, and I've never seen a Ducati dealership.
