I had to replace my front in the middle of last month and the new Pilot Road 2 was available. I had previously ridden out the Pilot Road 1, will excellent life (about 10k miles rear, and 14k front), and I look forward to a longer life with these guys. My riding is almost 100% commute and is about 600 miles a week. That said I have about 1500 miles on this new front tire (with a PR1 in the rear).
My initial impression was great!. The bike corner, and handled so much better. This is coming from the commuting perspective, so I don't know how they will do in the twisties, but if it is anything similar it should be very good.
As to the price, I think I paid $149 at Cycle Gear for the front, compared to $125 for the PR1. I believe the rears are also $195, vs the PR1 at $160. All told a set will cost you about a 20% increase. If life is extended by 5%, I think the benefits in handling, and wet road traction will make them a bargain.
