Husqvarna SMR450 definetly have a pure blast on it. Just be sure to include new tires right away. The things that come on the bike must be some sort of old dried out stock since they slip like ball bearings. I only used the 207's that came on my '05 for one session because of this. And apparently the 208's that come on the newer bikes are no better. Pirelli Diablos work sweet for me but any good rubber will make you grin.
