2020 Kawasaki Vulcan S

Engine

• SMOOTH & POWERFUL: Take command of the road with the Ninja®-derived, 649cc parallel-twin engine. Lightweight and responsive for easy handling and exceptional performance, the engine delivers smooth power with ample low- to mid-range torque and strong top-end power.

Engine Management Technology

• DUAL THROTTLE VALVES: 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.
• ECONOMICAL RIDING INDICATOR: Using high-precision electronic control for engine management, Kawasaki models can achieve a high level of fuel efficiency. However, fuel consumption is greatly affected by throttle use, gear selection, and other elements under the rider's control. The Economical Riding Indicator is a function that indicates when current riding conditions are consuming a low amount of fuel. The system continuously monitors fuel consumption, regardless of vehicle speed, engine speed, throttle position and other riding conditions. When fuel consumption is low for a given speed (i.e. fuel efficiency is high), an "ECO" mark appears on the instrument panel's LCD screen. By riding so that the "ECO" mark remains on, fuel consumption can be reduced. While effective vehicle speed and engine speed may vary by model, paying attention to conditions that cause the "ECO" mark to appear can help riders improve their fuel efficiency – a handy way to increase cruising range. Further, keeping fuel consumption low also helps minimize negative impact on the environment.

Ergo-Fit Adjustibility

• A PERFECT FIT: ERGO-FIT® is an exclusive sizing system that creates the perfect fit for riders of all sizes by offering adjustments to the bike’s seat, footpegs and handlebar to accommodate the rider’s height and reach. With 18 possible configurations between Reduced Reach, Mid Reach, and Extended Reach, ERGO-FIT helps produce a more comfortable and confident riding experience.

Performance

• LIGHT & RESPONSIVE: Sportbike-derived chassis and suspension provides light and responsive handling for easy maneuvering and sporty feel.
• ADJUSTABLE TO YOUR PREFERENCE: 7-way adjustable rear spring preload allows suspension to be set softer for added cruising comfort or stiffer for a sportier feel.
• OPTIMAL TRACTION: Sportbike-influenced wheels and tires contribute to the light-handling feel and provide confident traction.
