Ok, time for an update. I have put around 1000 miles on the BT-023's and so far I have nothing but good things to say. They are super sticky, predictably dive into corners, and stay put through the corner. Coming out of a hard turn also takes minimal effort to get the bike upright.
I have also ridden in the rain many times (this month has been brutal!) and the tires perform well on wet roads. I know its still too early, but they are wearing normally.
I have hit some tight corners pretty hard, have no real chicken strips left to speak of, and the tires have been solid every time. Crushed a long tight corner today at 55mph (getting on the FDR off the RFK bridge for any fellow New Yorkers) and felt comfortable and know I can hit it faster if I wanted to.
