Abstract
An adjustable motorcycle prop jack comprised of a hinging device with an over-center locking action for lifting and holding in place a motorcycle's rear wheel by lifting the motorcycle's right side over the pivot line formed between the tip of its side stand and the contact point of the front tire to facilitate maintenance requiring the rear wheel to spin freely. The invention is comprised of a base and lifting arm, and a pin and spacers inserted between the two to form a hinge. The motorcycle is lifted by placing the base of the invention perpendicular to, and on the ground, and the lifting arm under a lifting point on the rear right side of the motorcycle with the invention forming an obtuse angle. Upon engagement, the invention lifts the rear of the motorcycle off the ground and locks in an over-center position.
