I just replaced my Dunlops D207's with the common Bridgestone BT010/BT020 street setup and have been EXTREMELY impressed which the handling. These tires turned my bike into a new machine, I am so much more confident in the tires now...
Ofcourse I think for some strange reason my OEM D207's wore extremely bad becasue I don't see why Kawasaki would have put such a bad handling OEM tire on the bike....
IMHO, if you ran Dunlops before, try something different, how will you ever find out what tires brands and manufacturers you like better unless you try them?
