I put Pilot Road 3's on my last bike and was really happy with the grip and wet weather performance. It was a big heavy bike with so-so suspension but it could corner with those tires - I noticed they were grippier than the older Bridgestones they replaced.
However, they're a bit more costly than Roadsmart 2's, BT-023's, Metzeler Z8's and Pirelli Angels. So are the Continental Road Attack 2's.
From reviews in Bike magazine, I thought the Roadsmart 2's and Pilot Road 3's were the class leaders, but the Motorrad article ranked them differently. In truth I'm sure they're all quite good. I hope to put some miles on my VFR this year and the previous owner installed SS tires (Michelin Pilot Power's), so I'm sure I'll wear in nice flat spots and start looking for ST tires at some point.
