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.
• ABS (ANTI-LOCK BRAKE SYSTEM): Kawasaki ABS systems use front and rear wheel sensors to constantly monitor wheel speed. Should information from either of the sensors indicate that wheel lock has occurred, the ABS ECU directs the pump in the ABS unit to modulate brake fluid pressure (releasing and reapplying pressure so that traction can be regained) until normal operation resumes. ABS offers rider reassurance that contributes to greater riding enjoyment.
• ERGO-FIT®: Proper fit is key for rider comfort and control. However, the ideal fit varies from rider to rider, depending on their physical dimensions and riding style. ERGO-FIT® is an interface system designed to allow riders to find their ideal riding position. Various points of the chassis interface (the handlebar, footpegs and seat, etc.) can be adjusted through a combination of interchangeable parts and parts with adjustable positions. This enables a wide range of riders to find a riding position that offers both comfort and control. Feeling at one with their machine, they will be able to experience how Kawasaki machines are fun and rewarding to ride. *Adjustable parts and their range of adjustability vary by model.

Ergo-Fit®

• ADJUST YOUR RIDING POSITION TO FIT YOUR HEIGHT AND REACH: Take command of comfort with 18 different adjustable configurations to achieve your preferred fit.
• 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. After you purchase a Vulcan® S motorcycle, you’ll have the option to get fitted at no additional cost. And at dealerships with an ERGO-FIT Center, it's even more convenient to get fitted.
• 5'6" AND UNDER: This configuration is the starting point for shorter to average-height riders. The handlebar is positioned one inch closer to you for a confident riding experience, while the Reduced Reach sculpted seat is tapered and moves you two inches forward. Footpegs are placed rearward for an optimal leg stretch*. *Accessory shift-linkage rods required when changing footpeg position from standard.
• 5'7" TO 6'0": This configuration is the starting point for average-height riders. The handlebar is positioned to accommodate both average-height and taller riders. The Mid Reach sculpted seat is tapered for an easy reach to the ground and footpegs are placed in the standard position for optimal comfort.
• 6'1" AND OVER: This configuration is the starting point for average-height to tall riders. The handlebar is positioned to accommodate both taller and average-height riders, while Extended Reach sculpted seat moves hip support back an inch to provide extra room. Additionally, footpegs are placed forward for optimal leg comfort.* *Accessory shift-linkage rods required when changing footpeg position from standard.
