A motor vehicle having two front ground contact elements which may be wheels or skies or blades has a primary chassis with a frame, a motor, at least one rear wheel, a seat, and a front fork mount. Attached to the chassis and a front fork is a suspension and steering dolly with a central beam axle, individual outer front corner axles, rotatably mounted to spindles on outer ends of the beam axle, a steering plate rotatably mounted on a fulcrum carried by the dolly and operatively connected to both corner axles and to the fork, and resilient suspension enabling up and down and fore-aft movement of the dolly. The suspension is particularly useful for conversion of existing motorcycles and 3-Wheelers into vehicles having two front wheels or skies. Methods of suspending vehicles on two front elements,and converting single front element vehicles to two front element vehicles are also provided.
