ABSTRACT:
The present invention related a towing hitch for towing an up-sloped positioned motorcycle at the rear of a motor vehicle having a Class III receiver, the towing hitch comprising an anchoring support assembly attached to the Class III receiver, the latter including a L-shaped housing, a winch barrel pivotally attached between upright side walls and pivotal about a transverse axis and a winch belt operationally attached to the winch barrel and wound about a major circumferential portion of the front tire of the motorcycle. In one aspect, the full span of the circumference of the front tire is augmented by a metallic, arcuate pivot arm attached between and projecting from the side walls at the front of the L-shaped housing via a second transverse pivot axis positioned a distance D above the earth's surface where D is about equal to the radius R of the front wheel. In another aspect, the belt is bifurcated at its attached to the arcuate pivot arm to allow for easy attachment about the tread of the front tire. In yet another aspect, the L-shaped housing is pivotally attached at its rear wall along a vertical direction normal to the earth's surface relative to the Class III receiver. Result: the trailing capability of the motorcycle via the rear wheel only, is enhanced.
