Using high-precision electronics 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 signals when current riding conditions are consuming an optimally 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" emblem appears on the LCD screen of the instrument panel. By riding so that the "ECO" mark remains on, fuel consumption can be minimized.
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.
Electronic Cruise Control allows the rider to maintain a desired speed (engine rpm) with the simple press of a button. Because the rider does not have to constantly maintain the throttle position, this system allows relaxed cruising. This reduces stress on the right hand when traveling long distances, contributing to a high level of riding comfort.
Electronic Cruise Control is featured on Kawasaki's Vulcan 1700 / VN1700 Series cruisers and Jet Ski Ultra 300X and 300LX personal watercraft series. These models are equipped with an Electronic Throttle Valve system, meaning the throttle valves are not actuated directly by twisting the throttle grip (or pulling the throttle lever); rather, a position sensor on the throttle grip sends a signal to the ECU that determines the ideal throttle position. This is how Electronic Cruise Control is able to automatically adjust engine power to maintain vehicle speed when ascending or descending grades in the road. Without the precise control enabled by Electronic Throttle Valves, functions like Electronic Cruise Control would not be possible.
Kawasaki’s fully electronic throttle actuation system enables the ECU to control the volume of both the fuel (via fuel injectors) and the air (via throttle valves) delivered to the engine. Ideal fuel injection and throttle valve position results in smooth, natural engine response and the ideal engine output. The system also makes a significant contribution to reduced emissions.
Electronic throttle valves also enable more precise control of electronic engine management systems like S-KTRC and KTRC, and allow the implementation of electronic systems like KLCM, Kawasaki Engine Brake Control, and Cruise Control.
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.
With the press of a handlebar-mounted button, riders are able to activate the Fuel Economy Assistance Mode. This switches the ECU to a leaner fuel map in which ignition timing and fuel injection prioritize fuel economy. Rather than engine response or power, this mode favors reduced fuel consumption, aiming to increase fuel economy when riding at a constant speed. When riding in areas where gas stations are scarce, or when cruising across the continent, stretching your fuel efficiency is a considerable advantage.
Maximizing the effectiveness of the Fuel Economy Assistance Mode requires gentle use of the throttle. In the case of the 1400GTR / Concours®14, this means keeping engine under 6,000 rpm, throttle under 30%, and speed under 160 km/h (100 mph). Especially when used in conjunction with the Economical Riding Indicator, this mode can contribute to significant savings in fuel costs over long distances.
