I have just hit 10,000 miles on a set of Michelin Power Pilot 2TCs and love these tires. I bought my bike in Feb '09 with 3300 miles and plenty of tread on the stock tires. Since I had not ridden in 25+ years, I was not hard on the tires, as I was kind of a wuss on the bike. By July, right at 8,000 miles, the stock back tire was shot.
I put the Michelins on at the suggestion of the mechanics at Family Power Sports. $400 bucks installed. I live in the country and get to travel 40 miles RT everyday on a twisty, hilly, two-lane country road that seems to have been invented by God himself for bikes like the FZ6. I ride most of the road at speeds between 85 and 100 miles per hour. I have never felt the least bit concerned riding through these curves posted at 40-50 mph at speeds of 80-90 mph. The grip is fantastic and the wear is remarkable.
As I noted above, the stock rear tire was shot at 8k- no, I never do burnouts- but after 10K miles on the Power Pilot 2TCs, I still have at least 50% tread left. Good grip in the rain too. I guarantee that when I need to replace these tires, I will be putting the same back on.
