I will be studding one of my sets of tires. Much to my wife's dismay, I have 3 full sets to choose from. For the ATV's, there's only one class for the drag race- anything goes. For the Lemans there's two classes, the pro and the trophy class. I asked what the difference was and he said that the pro class gets to use the ice spikes and the trophy class uses studs. I'm not sure what I think of a 600ft drag race, but I will give it a shot. I'd sure like to see some Kawi's show up here because they are few and far between up here. There's a couple Can-am's around, but almost everyone has a Polaris or a Honda.
