I was refering to the Bridgestones. I would never buy them and get them installed on my own. If I buy a bike that has them, I'll run them. Other than that they make a good tree swing for the kids. I got 11,300 miles on my 2008 OEMs, but they wore very funny and front first. My 2010 has 8200 miles on it and the OEMs are toast. PR2s on my 2008 went just shy of 17,000 miles. I think the Bridgestones are the cheapest deal that Kawasaki could get or something.
