After flip flopping back and forth about which tires to get for my R6, I went with the Q2's (again). Had these on the 600RR.
At least I can give a fair comparo between the two bikes.
I really wanted longevity, as any real 'good' riding is about an hour away from me, and I was absolutely destroying my old Q2's with the long straights I had to endure just to get out to the good stuff.
Anyways, if anyone's interested, motomummy has them for $199 to your door (they also have the BT016 for $199 shipped). I couldn't overlook that as well...and as I'm going to try to start doing my own tire changes, I may have to pick up a second set.
Off to Jack Wilson for my tire changing tools...
