Suzuki has been a pioneer in the world of ATVs, and its introduction of the LT500 quad racer was just the beginning. While the massive 2-stroke behemoth resides primarily in history than on the every-day trails and dunes of the world, Suzuki continues to makes its claim on the off-road world of ATV action with such entries as the LTZ400 four-stroke and then the venerable LT-R450 quad, which is the dominant DOHC monster of motocross and GNCC racing.
