I have 2 bikes, a 2001 gsxr-600 and a '05 gsxr 750. I currently am running michelin pilot powers on my 600 as I ride that at the track often and ride it hard on the street. I am almost ready to get a new rear for the 750 and just wondering what everyone is running. I know the pilot powers don't last very long, and I probably will be riding my 750 hard, but not at the track and commuting with it from time to time. Anyone have any suggestions? I was thinking about trying the pilot sports or the Metz MZ6. I love the twisties, but would like to get a little more than 5k on a tire. Thanks!
