The 903cc V-twin powered Kawasaki Vulcan 900 Line models have all the style and attitude of a one-of-a-kind build. From the detailed paint job to the intense exhaust, Vulcan 900 machines are an artful expression of individuality. Enjoy the dynamic fusion of hand-built design and premium fit and finish—a tantalizing combination that could only come from Kawasaki.
Late-model sport bikes often use large-bore throttle bodies to generate high levels of power. However, with large diameter throttles, when a rider suddenly opens the throttle, the unrestricted torque response can be strong. Dual throttle valve technology was designed to tame engine response while contributing to performance. On models with dual throttle valves, there are two throttle valves 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, opened and closed by the ECU, precisely regulates intake airflow to ensure a natural, linear response. With the air passing through the throttle bodies becoming smoother, combustion efficiency is improved and power is increased.
