A jack for lifting and for supporting a motorcycle so that one of the two wheels of the motorcycle is elevated above a planar supporting surface while the other wheel contacts said surface, said motorcycle including a frame intermediate the two wheels, said frame having a minimum clearance between the frame and the supporting surface, said jack comprising: a lifting frame defining a plane, said lifting frame having an upper element, a lower element, a length, a width and a height, a substantially planar contact element mounted on the upper element of the lifting frame so that the plane of the contact element is substantially parallel to the plane of the lifting frame and is adapted to establish substantially linear engagement with the underside of the frame of a motorcycle to be lifted and supported; a foot having a substantially planar bottom surface, said foot being mounted on the lower element of the lifting frame so that the plane of the bottom surface of the foot is substantially perpendicular to the plane of the lifting frame; said bottom surface of the foot having a length substantially equal to the length of the lifting frame and a width substantially greater than the width of the frame; and elongate handle means having a substantially linear axis connected to the upper element of the lifting frame so that the axis of the handle means is substantially perpendicular to the plane of the lifting frame for rotating the contact element relative to the lower element of the lifting frame to lift and support a motorcycle, said motorcycle having one wheel engaging the support surface and its frame engaging the contact element; whereby, when the jack is supporting a motorcycle, the bottom surface of the foot is substantially in contact with the supporting surface and the handle means is spaced above the supporting surface and substantially parallel to said surface.
