I agree with Bob 100% !!! Discovered this from Honda Rune owners in England that were having the right side of their front tires wearing faster then the left side.
Honda Rune owners in the USA and Canada were having the left side wear out faster. It didn't help that the crappy Dunlops came with only 7/32nds of rubber.
When we turn left at intersections, lean and accelerate... we travel 40-60 feet on the left side of the tire. When we turn right, lean and accelerate... we travel 20-25 feet before returning to the upright position. The left side normally sees more pavement here in the USA. It is NOT an alignment/fork issue.
