Abstract
Abstract A motorcycle throttle gripper having two friction levers with one friction lever positioned below the throttle grip hand control and closely mounted brake lever hand control and with one friction lever positioned above the throttle grip hand control and closely mounted brake lever hand control. On each of the two friction levers a rounded concave offset section seats on and grips the throttle grip hand control roughly similar to an external brake band or segment of a brake band around a brake drum or wheel. Also, on each of the two friction levers a straight section is mounted in sliding contact with the forward brake lever hand control. On the three embodiments of the invention the upper and lower friction levers are held in friction contact to the throttle grip hand control and the brake lever hand control by means of tension producing rubber bands, elastic members, or by means of tension producing springs, bolts, and self locking nuts. The combination of the direct rotational friction contact with the throttle grip hand control and the direct sliding friction contact with the brake lever hand control results in a lever system which provides efficient near zero backlash for the operation of the invention. This means that even a slight change in the rotational throttle grip hand control speed setting will be held at that setting by the efficient two friction levers in the system of the invention.
