A system for laterally stabilizing a two-wheeled vehicle includes a pair of outrigger struts having respective outrigger wheels on opposite sides of the rear wheel, vertically movable between raised and lowered positions relative to a supporting structure, the struts each being connected by a transverse strut shaft for unison vertical movement and extending forwardly of the strut shaft; an electric motor driven actuator mechanism including a rotatably mounted lead screw shaft that is pivotably mounted relative to the supporting structure, a drive nut threadingly engaging the lead screw shaft that is connected to the strut shaft for driving the wheels between the raised and lowered positions in response to rotation of the lead screw shaft. A controller for electrically powering the motor includes pilot circuit paths of a bidirectional motor bridge circuit, the pilot circuit paths being electrically powered only when motive power of the vehicle is enabled, the actuator mechanism in combination with the motor having sufficient drag and mechanical advantage whereby the outrigger wheels are locked from movement between the raised and lowered positions in the absence of electrical power to the motor. Limit switches are connected for inhibiting corresponding ones of the pilot circuit paths for preventing overtravel of the outrigger wheels.

A system for laterally stabilizing a two-wheeled vehicle having a steerable front wheel, a rear wheel, and a chassis connecting the front and rear wheels, the system comprising: (a) a support structure including a U-shaped frame member having leg portions rigidly attached to the vehicle chassis and a transverse portion located rearwardly of the rear wheel, a base member, and means for rigidly attaching the base member to the transverse portion of the frame member to form a substantially horizontal shelf portion extending rearwardly of the rear wheel; (b) a laterally oriented strut shaft rotatably mounted transverse to the base member behind the rear wheel and extending on opposite sides thereof; (c) a pair of outrigger struts having respective outrigger wheels rotatably mounted at forward ends thereto, the struts being rigidly connected at their rearward ends to the strut shaft for locating the outrigger wheels in parallel spaced relation on opposite sides of the rear wheel, the outrigger wheels being vertically movably positionable between a raised position and a lowered position relative to the base member; (d) an electric motor supported by the base member; (e) an actuator mechanism comprising: (i) a rotatably mounted lead screw shaft operatively coupled to the motor for being driven thereby; (ii) a drive nut member threadingly engaging the lead screw shaft; and (iii) the lead screw shaft and the drive nut member being mechanically connected between the strut shaft and the motor for driving the strut shaft and thereby pivoting the struts and the outrigger wheels in unison between the raised and lowered positions in response to rotation of the lead screw shaft; and (f) a controller for electrically powering the electric motor for selectively positioning the outrigger wheels.
