I've only ridden the Race compound, and you DO NOT want them for the street. Since they're race tires you have to get them VERY warm for them to grip at all, which is almost impossible on the street, and until you do its like riding on ice. Very scary tires for the street, from my experience. But that's only the race compound, haven't tried the other compounds.
What's up Tim? You're sliding the rear now eh? I'll bet you've gotten A LOT better since we rode together at DRA. When are you going to Willow next? I'm hoping to get back on a bike in a month or so, dying to get to the track soon thereafter
