when I first got my 07 ZX-6r I put a 190 pirelli super corsa rear on it mostly because that's what I had on my GSXR. That's what I used all year but now I've been thinking I may switch to the stock 180 size this year. I've been hearing different things, just curious on what you guys think. Also considering maybe switching to the bridgestone 003 tires also. Who knows, off season means too much time to think!
