I was using Pilot Sports, then went to the M1. I was getting about 2k out of those ( rear).
I put on the Z6 and am getting 4k now. At first I was feeling a bit more "Squirm" out of the front. It never slipped just felt odd. I think it had to do with the tread pattern and depth. I ride twisties mostly and the Z6 is as good as the Pilot for my ability. I can't tell the differance between the two. Other than the price ofcourse
