I have a Pilot Road 2 on the back of my bike, which was on there when i bought the bike, and have done about 2500 km's since, including quite a bit of sport riding, and it seems to hardly worn at all.
I just put a Pilot Road 2 on the front, and have ridden about 400km's on them including 300 km's of sport riding, and the dimples that are in the middle of the tyre when the tyre is new, have still not worn off completely!
Am thinking i will be getting some pretty decent mileage out of these hoops! Best part is, they perform faultlessly from my point of view....bike handles beautifully, especially since i put the pilot on the front, much better than when i had the dunlop on the front.
Cant reccomend these tyres enough! great grip, long mileage.
Lastly a good friend has Pilot Road 2's on his Hayabusa, and another with a z1000, both guys cant speak highly enough of them either.
