I thought whenever they went to the bigger tire for superbike they all went to it? Some like it better than others, just like when they changed the 600 tire. Had a great weekend just hanging out and roaming around. We got lucky with the wind blowing the smoke away. Can't wait to get out there myself in a couple of weeks, if not sooner.
Toni said a lot about it in my Fri interview w/ him. its on page4 of this thread. a few of Kev's Saturday interviews had some info about them too. Herrin talked about it a tiny bit and 1 or 2 others IIRC. I don't know anything more about it.
Someone tell Josh about the N2/WERA endurance series......I'm sure he knows but it would have nice for a shout out.
