Abstract: An auxiliary throttle attached to the underside of the throttle mechanism of an off-road type vehicle, such as a snowmobile. It is positioned on the backside of the handlebar and is operated by the thumb. The device has a stop built in that prevents the rider from engaging the throttle at more than half speed using the bar. The rider can increase speed, but only by using the main throttle. This has three beneficial effects. First, it provides a convenient and easy method for riders to operate the throttle without fatigue. Second, it is operated by the thumb, just like the main throttle, thereby preventing confusion in an emergency. Third, it limits the speed the vehicle can operate, no matter how hard the device is gripped. Thus, in a panic situation, gripping the handlebar does not cause any sudden burst of speed.

Abstract: A cruise control for a vehicle having a throttle controller mounted to a handlebar is provided. The cruise control includes a throttle-pipe handle having a throttle-pipe spur gear attached thereto, a cruise control spur gear coupled to the throttle-pipe spur gear, an electromagnetic brake/clutch device coupled to the cruise control spur gear, an activation switch, and a control circuit. The cruise control spur gear may be coupled to the throttle-pipe spur gear via an intermediate spur gear. The control circuit provides a control signal to activate the electromagnetic brake/clutch device when the activation switch is actuated. When activated, the electromagnetic brake/clutch device prevents rotation of the throttle-pipe handle. When the braking system of the motorcycle is activated, the control signal provided to the electromagnetic brake/clutch device is removed, which deactivates the brake/clutch device, allowing free rotation of the throttle-pipe handle.

Sprockets in the differential are locked into offset positions, during conventional and round steering, to maintain proper steering angle correction, even under heavy loads. Active idlers are mechanically linked within the steering unit to automatically maintain appropriate chain tension, in all steering modes.
