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.

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.
