Well the z6s don't handle quite the same after you do this to the rear:
I don't think those metal strands are supposed to act as wear bars...
This was after about 5k with a lot of Interstate riding loaded with gear, plus I think I was a few pounds low on pressure.
I'm actually thought I'd try the Diablo Stradas this time 'round.
I think I actually like them better. I hear Pereli owns Metzler and the Stradas are made of the same compounds as the z6s. They certainly grip. I think I like the profile of the Stradas better. While the z6s let the bike flip into corners due to the more triangular profile, the stradas are more gradual and grip at whatever angle I put the bike at. I think they also make it easier to move back and fouth from different lean angles.
