ABSTRACT:
A multi-purpose motorcycle lift includes a base, a lift assembly, and a lift bar. The left leg is pivotally connected to first end of the base, and the right leg is pivotally connected to the second end of the base, such that the left and right legs pivot freely with respect to the base. The front side of the left and right legs are pivotally connected to the front support, and the rear side of the left and right legs are pivotally connected to the rear support. The front and rear supports pivot in a parallel motion to the base. One end of the lift bar is fastened to the left leg and a stirrup protrudes from the other end such that a user may insert a shoe. The user operates the multi-purpose motorcycle lift by inserting a shoe into the stirrup and pushing downward until the left and right legs contact the base. A shot pin may be inserted through the pair of projections to insure that the multi-purpose motorcycle lift doesn't return to a retracted position. Retraction is accomplished by removing the shot pin, inserting a shoe through the stirrup, and pulling upward on the stirrup until the lift assembly passes over the center of gravity and then using downward force of the foot to gently allow multi-purpose motorcycle lift to return to the retraced position.
