So if tracks are such a good idea, why do ATVs have wheels? Because wheels work better in all but the most extreme conditions. A track kit adds more than 150 pounds to an ATV and makes it wider and longer. Tracks also make ATVs harder to steer at low speeds while creating mechanical drag that sucks up horsepower. That said, if you spend a lot of time on boggy ground, as waterfowlers do, or in deep snow, a track kit might be just the thing to keep your ATV working all year round.
