ABSTRACT:
A motorcycle jack includes a frame having front and rear cross shafts rotatably supported thereon. Pairs of front and rear legs are secured to opposite ends of the respective front and rear cross shafts for rotation in unison with the shafts. A linkage mechanism interconnects the front and rear shafts for rotation in unison, but in opposite directions so that the frame is raised in response to pivotal movement of the front and rear legs toward one another and is lowered in response to pivotal movement of the front and rear legs away from one another. A power unit is provided for rotating their legs relative to the frame. The cross shafts are preferably formed of a resilient material so that the free left legs tend to spread slightly further apart than the interconnected right legs, thereby tilting the motorcycle slightly to the left for placement onto its kickstand when the jack is lowered.
