Modern sportbikes often use large-bore throttle bodies to generate high levels of power. However, with large-diameter throttles, when a rider suddenly twists the throttle, the unrestricted torque response is anything but gentle, and often more than the rider can handle. Dual throttle valve technology was designed to tame engine response while enabling high performance.
On fuel-injected models, throttle bodies generally have only one throttle valve per cylinder. On models with dual throttle valves, there are two per cylinder: in addition to the main valves, which are physically linked to the throttle grip and controlled by the rider, a second set of valves, controlled by the ECU, precisely regulates intake airflow to ensure a natural, linear response. With the air passing through the throttle bodies flowing smoothly, combustion efficiency is improved and power is increased.
Like other Kawasaki engine management technology, Dual Throttle Valves were designed with the philosophy of "following the rider's intention, while providing natural-feeling support." They are featured on many Kawasaki models.
