I put those on my 2005 FZ6 I just bought, and another set went on my 2011 FZ8. Trust me, you can't go wrong with the PR2's.
Only thing bad I've ever heard about them is that they arent the quickest tires to warm up. But I've been riding this week with spanking new tires (on both bikes) in 20F (-5C) temperatures (no need to say it's risky business...)...and though I'm very careful in the curves, didnt have one slip. Not saying you go full throttle from the get go, but in the summer, I never experienced anything stressful with these tires, they give good feedback, handling and stick like glue.
