Throttle Tender Motorcycle Cruise Control Assist The Throttle Tender Motorcycle Cruise Control Assist is designed and patented by Barefoot Willies, the same company that brought you the most trusted motorcycle cup holder in the business. Our patented design was created specifically for the five pointed thumb screw in Harley Davidson models, so this product is a seamless addition to any Harley bike. Easily installs in seconds and, once engaged, allows the throttle to stay open without the use of either hand. A simple push of the thumb engages the tender and a push with the finger disengages.
