Abstract: A lightweight trailer suitable for towing behind a motorcycle is convertible to a trailer operative to transport the motorcycle behind another towing vehicle. An axle slider employs a parallel linkage to easily adjust trailer axle width. The design also shifts the center of gravity of the trailer to provide a balanced load as a motorcycle cargo trailer and as a motorcycle-hauling trailer. To attain the additional length and trailer hitch height necessary for hauling the motorcycle, a frame extension and an offset tongue extension are provided. This offset tongue also provides attachment points for conventional motorcycle tie-down straps. A loading ramp is provided to allow for easy loading of the motorcycle.
