All terrain vehicle

An all terrain vehicle comprising

• a center of gravity;
• a frame including a front, a rear, two opposite sides and straddle seating having a driver seat with an upper surface;
• front wheels each having a first center and a first inner extent and supporting said front of said frame and mutually spaced on said opposite sides thereof;
• rear wheels each having a second center and a second inner extent and supporting said rear of said frame and mutually spaced on said opposite sides thereof;
• an engine carried longitudinally between said front and said rear wheels by said frame at substantially the mid point longitudinally between said front and said rear wheels;
• footpegs fixed to said frame and extending to distal ends laterally outwardly of said frame, said footpegs being associated with said straddle seating and positioned to opposite sides, respectively, of said frame below and substantially aligned longitudinally of the vehicle with said center of gravity of the vehicle, said distal ends of said footpegs being inwardly of said inner extent of said front and rear wheels;
• tires on each of said front and rear wheels each extending to a lowermost extent, said tires on said rear wheels being of a diameter and location relative to said frame such that said tires on said rear wheels extend into a cylindrical space having an axis extending laterally of the vehicle substantially aligned longitudinally with and below said center of gravity of the vehicle and said space having a diameter equal to the distance between the undermost side of said frame where aligned substantially longitudinally with said center of gravity of the vehicle and a level surface containing said lowermost extent of said tires, said front and rear tires being mounted such that the longitudinal spacing between said front and rear tires is substantially equal to the radius of said rear tires, said first and second centers of said front and rear wheels being arranged to form substantially a square in plan, said footpegs being located midway between said said upper surface of said driver seat and a level surface containing said lowermost extent of said tires;
• swing arms pivotally mounted to said frame and rotatably mounting said rear wheels, said swing arms having an effective length less than the radius of each of said tires on said rear wheels.
