An apparatus capable of temporarily limiting travel of the rear suspension system of a motorcycle for the purpose of obtaining better traction when accelerating. The apparatus includes a device having a first base secured to at least one frame member of the motorcycle at a location above a rear suspension member of the motorcycle, and a second base secured to the rear suspension member at a location in proximity to the first base. A post is pivotally mounted to the first base to have first and second positions. In the first position, the post extends toward the second base an engages a retention feature in the second base to prevent movement of the rear suspension member and frame member toward each other. In the second position, the post is disengaged from the retention feature and pivoted away from the second base to permit movement of the rear suspension member and frame member toward each other.
