Very informative. When I bought my bike, the front Michelin Macadam was cupped really bad, I thought it was because of ineffective dampening,(like a bad shock on a car) I had the front forks checked out, and it was fine. Now that the article mentions it, the Macadams were a lot more square cut. I put 1,500 road miles + 1 track day on my heavy Kat, and these michelin Pilot pros are still looking good, my bank account after the tire purchases is looking bad.
