Ashe speaks truth.My PR2s were installed just before EOM, and after chasing Jeff & Jason over Rt 311, I concurr that they're an 85% tire for the FJR. At hard lean, they just get a little gittery. So long as you don't push into that remaining 15% of the FJR's abilities, they're wonderful.
The rear is a great 2-up tire...nice and stiff. At 2400 miles today, I can tell this will be the longest treadlife set so far; they look practically new. If you're not a peg scraper, these are the tires for you, hands down. However, if you play MotoGP on the weekends, the Roadsmarts will serve you better.
One more note:
I've ridden a few times since EOM in higher temperatures, and noticed that the PR2's stick better. Yesterday, I scraped pegs at high speeds several times, with no traction loss at all. The temperature was mid- 80s, vs. low 70s @ EOM. Above 80 degrees, I might call this a 95% tire (will wait for Jeff Ashe's opinion on this).
For me, this probably makes the PR2s the perfect choice for Summers, when higher temperatures will effectively soften the tire (and eat them up quicker), and improve extreme lean performance. But I intend to switch back to the Roadsmarts for cooler weather, as the PR2s are too hard for my tastes, below 75 degrees.
