What is it? What causes it? Does the tire just need to be replaced or is there something mechanically wrong with the motorcycle that needs to be fixed (ex. suspension etc.)??
Cupping comes in two styles. One is a oval shaped depression usually found in the center of the tread and can be caused by under inflation, bad shocks or unbalanced tires. A cup usually encompasses several tread blocks. The other is found on the tread blocks at the edges of the tread, usually the block either side of the center. Each one wears on the front or rear of the block, not the side. When you slide your hand across the tire, you get the impression of the tread feeling like the teeth on a saw. This type of wear is more pronounced on some tires than others and is caused by the fact that in a motorcycle tire, the tread is rounded instead of flat like a car tire. Because of that, the distance around the center of the tire is more than on each side and as a result, the tread blocks off center must slip a little bit as the tire rotates. The worst tires I ever had with the second type of cupping was the old K112 Continental front tires. They has long rectangular blocks and the two on each side of the center two would wear much worse than the center two. The rear Dunlop Elite 3 on my big bike has some as well but the front Dunlop 404 or Qualifier Elites have never done it at all.
they give you 7-10 more horsepower about the same as a 150cc scooter!
answer is , No . If they did ,believe me ,chevy would have done it.
