A half-track all-terrain vehicle having an independent suspension system that provides an improved vehicle ride and facilitates traversing obstacles. The vehicle includes a frame, a pair of beams that each holds front and rear wheels, and a suspension system extending between the each beam and the frame. The suspension system includes a plurality of cushions.
