only negative i heard was that they were slow, but thats coming from people who've been doing trackdays on 600s and stuff, and even they had a blast once they got out and mixed it up with some people and realized how much more you can concentrate on what you're doing instead of just keeping the bike under you.
i can't wait to get it out on the track. its driving me crazy. can't wait to brag and post picts of all our mods too
.... it'll happen soon enough i suppose
