I've had the Metzlers for a few weeks now and gotten about two hundred miles of both highway and city riding. So far, I really haven't noticed any difference between them and the OE Dunlops. Ride is smooth, grip seems to be about the same and I put quite a bit of lean into the bike around turns. All in all, they seem to be a pretty good purchase. Guess I'll know once I get ten thousand miles on them and see where I'm at.
