ATV Throttle Ext: This thumb throttle ext works on most ATV thumb throttles. We do not recommend using this throttle ext with oversized or oddly shaped thumb throttles. Also be careful not to use it with handlebar gloves or protective gear, as the ext may get caught under the gloves, causing unintended acceleration. Enjoy a More Comfortable Riding Experience: This throttle ext features an ergonomic rubber shape design that provides multiple thumb positions and leverage, allowing the rider to control the throttle with the palm of the hand instead of the thumb, helping to reduce thumb and hand fatigue caused by long rides. Customizable: This ATV throttle ext is made from bendable stainless steel and covered with a soft rubber coating to withstand long-term riding use. It bends and forms easily to fit either large or small hands comfortably. Easy to Install: This thumb throttle ext has a two-piece clamp design for easy bolt-on installation. The stainless steel portion clamps onto the thumb throttle to provide reliable throttle control. Fit Any Size Hand: This ATV throttle ext is suitable for large or small hands. It comes with a mini wrench for easy installation and adjustment. Please read the pictures and details below carefully before ordering.
