Electronic Cruise Control

Electronic Cruise Control allows a desired speed (engine rpm) to be maintained with the simple press of a button. Because the rider does not have to constantly control the throttle, this system allows relaxed cruising. This reduces stress on the right hand when travelling 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. 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, which in 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 are encountered. Without the detailed control offered by Electronic Throttle Valves, functions like Electronic Cruise Control would not be possible.

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 minimise negative impact on the environment.

Fuel Economy Assistance Mode

By pushing the handle switch, riders are able to activate the Fuel Economy Assistance Mode, switching the ECU to a leaner fuel map in which ignition timing and fuel injection prioritise fuel economy. Rather than engine response or power, this mode favours reduced fuel consumption, aiming to increase fuel economy when riding at a constant speed. When riding in areas where gasoline stands are scarce, or when cruising across the continent, being able to make the same amount of fuel last longer is a considerable benefit. 

Maximising the effectiveness of the Fuel Economy Assistance Mode requires a gentle use of the throttle. In the case of the 1400GTR / Concours 14, this means keeping engine rpm under 6,000 rpm, throttle under 30%, and speed under 160 km/h. Nevertheless, especially when used in conjunction with the Economical Riding Indicator, this mode can contribute to significant savings in fuel costs over long distances.
