Abstract
Abstract Discloses a device for use with a towing vehicle to tow a twowheeled vehicle having a pivotal front wheel and a rear wheel. The device includes a hitch-bar assembly, detachably attached to the rear of the towing vehicle, carrying a frame assembly which carries a mounting bracket assembly. The pivotal front wheel is raised off the ground and rests on elongated channels of the mounting bracket assembly which has middle spacer plates providing lateral support for the front wheel. Spring-tension adjustable main springs mounted laterally of the front wheel on the mounting bracket assembly and on the spring forks of the motorcycle maintain the motorcycle upright in straight ahead movement of the towing vehicle and allow the motorcycle to track the towing vehicle taking a curve or deviating from straight ahead movement by tilting or canting movement of the motorcycle corresponding to the tilting or canting movement of the towing vehicle taking a curve or deviating from straight ahead movement. Spring-tension adjustable auxiliary springs similarly mounted function as a safety factor for the main springs in case of their malfunction or breakage. The frame assembly is carried on the hitch-bar assembly to be rotatable for up and down return movement of the frame assembly and thereby the mounting bracket assembly when the rear wheel of the motorcycle hits a bump.
