im running maxxis supermaxx sports on my zx6r. I'm getting on with them ok in the dry. scrubbed in quite fast and despite being a fairly novice rider, they have given me some confidence. they warm up quickly as well. only downside to them (or me) is that they are horrible in the wet. i dont like them at all when its raining but that is just my opinion. the others in there range are apparantly much better in other conditions
