I mounted new front and rear tires on my 1300C. Both were balanced, but my question is how often during the life of the tires should they be balanced? The front was easy enough to remove but the rear was a pain in the butt with the stock exhaust in the way of the large retaining nut for the rear axle. It took two of us to do it. For my cars I usually get them balanced about every 8,000 miles or sooner if I notice wobble at highway speeds.
