ATV Throttle Ext: This thumb throttle ext is compatible with most standard ATV thumb throttles. It is not recommended for use with oversized or unusually shaped thumb throttles. Avoid using it with handlebar gloves or protective hand coverings, as the ext may become trapped under the material, potentially leading to unintended acceleration. Enjoy a More Comfortable Riding Experience: Featuring an ergonomic rubber design, this throttle ext offers multiple thumb positions and improved leverage. It allows riders to operate the throttle with the palm of the hand rather than relying solely on the thumb, helping reduce hand and thumb fatigue during extended rides. Customizable Fit: Constructed from flexible stainless steel and coated with soft rubber, this throttle ext is built to endure prolonged use. It can be easily bent and shaped to suit both large and small hands for a personalized fit. Easy Installation: Designed with a two-piece clamp system, this ext attaches quickly and securely to the existing thumb throttle. The stainless steel component ensures stable and reliable attachment without tools in most cases, though a mini wrench is included for adjustments. Universal Hand Size Compatibility: Suitable for riders with various hand sizes, this ext provides a comfortable grip and control solution. A mini wrench is included for straightforward installation and fine-tuning. Please review all product images and details carefully before purchase.
