Throttle Boss Iso 1st
Description Added to the popular Küryakyn ISO-Grips, this little jewel can make all the difference in the world on a long ride. The Throttle Boss is a small adjustable paddle that is positioned under the palm of one's throttle hand. This allows the driver to slightly relax the grip on the gas and still maintain a constant speed. Muscle stiffness and fatigue are reduced after prolonged cruising at a steady pace. Fits all ISO-Grips. A new redesigned rubber pad permits use on both grips for a matched set.
