Abstract
A hydraulically operated throttle system that has the hydraulic system components installed entirely within the throttle grip on the handlebar. A regular throttle cable is run through the frame/handlebar where it connects to the hydraulic system. A three-piston system is used to provide the control. One piston is connected to a disk cam. As the disk is turned (by turning the twist grip), the cam forces the first piston to move, which forces hydraulic fluid from a first cylinder into a secondary cylinder. This secondary cylinder contains a second piston, which is moved by the fluid from the first cylinder. As this second piston moves, hydraulic fluid moves third piston within a third cylinder. The third piston is attached to the throttle cable. As this piston moves within the third cylinder, it pulls or pushes the throttle cable, thereby opening or closing the throttle on the engine.
