I have to say I echo the Michelin PS4S comments - I had two new fronts on my FK2 in August (annoyingly only did about 1k miles before I accidently bought an FK8.) and the grip and warm-up was so much better than the Continentals in cold, wet conditions. Now in my FK8, the Continentals are just over half worn and I went into a fast roundabout in cold, semi-damp conditions a couple of weeks ago and lost the back end under trail braking on turn-in and had to have two stabs of opposite lock to get it right. The FK2 with new Michelins was fine at that speed around the same corner in similar conditions. The Continentals provide more initial bite in my experience, but I'd say the Michelins can do 90-95% of what the Conti can but last twice, even three times as long.
Only thing is there is a huge price difference between a couple of Michelin 19"'s for the FK2 and the 20" for the FK8.
