A portable motorcycle hoist has a main frame assembly which includes a pair of vertically-oriented parallel channel beams rigidly affixed to both an upper cross brace and to a base member. The pair of channel beams provide a caged track for a trolley which is movably slideable therein between a lowermost position and an uppermost position. The trolley is fitted with a plurality of guide wheels to minimize sliding friction within the caged track. A cradle assembly, adapted to support a motocycle beneath its engine, is attached to the trolley. Attachment may be made with welds, threaded fasteners, or the cradle may simply be clipped to the trolley. The base member may be unitary, or it may be partially disassemblable to facilitate transport and storage. The base member may also incorporate casters to facilitate the repositioning of a supported cycle. A first preferred embodiment of the invention includes a first pulley mounted on the upper cross brace, a second pulley mounted on the trolley, and a battery powered electric-motor-driven winch mounted on the base member. A second Preferred embodiment of the invention utilizes a rail jack to raise and lower the trolley.
