ABSTRACT:
An all terrain vehicle has an adjustable suspension system. The adjustable suspension system features a first spring and a second spring. An intermediate member is positioned between the two springs and may travel in an axial direction along with at least a portion of one of the springs. A travel limiting member, movable by a cam and follower system, is positioned relative to the intermediate member such that the travel limiting surface may stop the movement of the intermediate member thereby disabling at least one of the first and second springs. The cam and follower mechanism is operated via a shifting lever positioned within a recess proximate a seat of the all terrain vehicle and in a location protected from the undercarriage of the all terrain vehicle.
