Modified Quad: All quads must be equipped with a functional tether type kill switch, and must have flat-track type tires on the rear axle.  No knobby type tires will be permitted. 52" maximum width.  Quads with water-cooled engines will be run in the modified class.

Stock Quad: All quads must be equipped with a functional tether type kill switch, and must have flat-track type tires on the rear axle.  No knobby type tires will be permitted.  Stock means that the engine and suspension must be stock, although the suspension may be strapped down.  Sway bars will not be permitted. Nerf bars may be added.  The promoter has the final say in whether your quad is stock.
