KCMF (Kawasaki Cornering Management Function):
Using the latest evolution of Kawasaki’s advanced modelling software and feedback from a compact IMU (Inertial Measurement Unit) that gives an even clearer real-time picture of chassis orientation, KCMF monitors engine and chassis parameters throughout the corner – from entry, through the apex, to corner exit – modulating brake force and engine power to facilitate smooth transition from acceleration to braking and back again, and to assist riders in tracing their intended line through the corner. The systems that KCMF oversees vary by model, but may include:
- S-KTRC/KTRC (including traction, wheelie and sliding control)
- KLCM (including traction and wheelie control)
- KIBS (including pitching and corner braking control)
- Kawasaki Engine Brake Control

Drawing on the know-how and technology possessed by the KHI Group, Kawasaki’s supercharged engine delivers high engine output while maintaining a compact design. The key to achieving this incredible performance lies in the engine’s supercharger – a motorcycle-specific unit designed completely in-house with technology from Kawasaki’s Gas Turbine & Machinery Company, Aerospace Company and Corporate Technology Division.
One of the greatest benefits of designing the supercharger in-house and tailoring its design to match the engine’s characteristics was that engineers were able to achieve high-efficiency operation over a wide range of conditions – something that would not have been possible by simply dropping in or trying to adapt an aftermarket automotive supercharger.
The importance of high efficiency in a supercharger is that, as the air is compressed, power-robbing heat gain is minimal. And while many superchargers are able to offer high-efficiency operation in a very limited range of conditions, Kawasaki’s supercharger offers high efficiency over a wide range of pressure ratios and flow rates – meaning over a wide range of engine speeds and vehicle speeds. This wide range of efficient operation (similar to having a wide power band) easily translates to strong acceleration. The supercharger’s high efficiency and minimal heat gain also meant that an intercooler was unnecessary, greatly saving weight and space, and enabling the engine’s compact design.

KTRC (3-mode, 9-levels)
(Kawasaki TRaction Control)
3-mode, 9-level KTRC combines the best elements of Kawasaki’s earlier traction control systems. Riders can choose from three modes, each offering a progressively greater level of intrusion. Within each mode there are three rider-selectable levels, adding more or less intrusion (rider preferences for each mode are programmable for easy on-the-move selection from the left handle), for a total of nine possible settings. Riders may also elect to turn the system off.
The new KTRC system combines the logic and control of Kawasaki’s earlier traction control systems (S-KTRC, 1-mode KTRC) in each mode. Primary operation is similar to S-KTRC, which prioritises maximum forward acceleration using predictive-style intervention. But should excessive rear wheel speed be detected while operating in any mode, engine output is reduced to a level where grip can be regained, which provides rider reassurance by facilitating smooth riding on slippery surfaces.
Depending on the model, a Rain Mode is also included. This can be turned on and off independently of KTRC. Activating Rain Mode sets KTRC to Mode 3+, and also limits power output, torque and response. Similar to a Low Power setting, maximum engine output is reduced, and throttle response is milder.

Kawasaki Engine Brake Control
The Kawasaki Engine Brake Control system allows riders to select the amount of engine braking they prefer. When the system is activated, the engine braking effect is reduced, providing less interference when riding on the circuit.

Designed to assist riders by optimising acceleration from a stop, KLCM electronically manages engine output to prevent wheelspin when moving off. Riders can choose from three modes, each offering a progressively greater level of intrusion. Each mode allows the rider to leave from a stop with the throttle held wide open.

Designed to help riders maximise their acceleration on the circuit by enabling clutchless upshifts with the throttle fully open, KQS detects that the shift lever has been actuated and sends a signal to the ECU to cut ignition so that the next gear can be engaged without having to use the clutch. Depending on ECU settings, clutchless downshifts are also possible.

Electronic Throttle Valves
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.

(Sport-Kawasaki TRaction Control)
S-KTRC (Sport-Kawasaki TRaction Control), Kawasaki's original predictive traction control, uses the same base technology as the Kawasaki works machines that competed in MotoGP, the pinnacle of motorcycle racing. This technology continually controls the rear wheel slip that occurs when power is applied, ensuring optimal acceleration. In general, maximum forward drive requires a certain amount of slip (usually between 20-30% slip ratio, i.e. the rear wheel is turning 20-30% faster than the front). To ensure the most effective transfer of power to the tarmac, S-KTRC monitors the slip ratio in real time, and governs engine power delivery to optimise rear wheel traction.
S-KTRC monitors a number of parameters, including front and rear wheel speed, engine rpm and throttle position. Conditions are confirmed every 5 milliseconds, at which time the system looks at each of the parameters as well has how much they are changing (i.e. their rate of change). This unique Kawasaki method makes it possible to interpolate and predict how the bike will behave in the next instant.
Unlike 1-mode KTRC, which cuts power as soon as rear slip is detected to allow rear traction to be regained, S-KTRC uses minimal power drops to ensure the slip ratio for optimal traction is maintained. Because its goal is to maximise acceleration, as long as sufficient forward motion is observed, this sport riding system will allow power wheelies as the bike comes out of corners.

(Kawasaki TRaction Control)
When accelerating on a slippery surface, it is easy for rear wheel spin (i.e. when the rear wheel turns faster than the front wheel) to occur. KTRC (Kawasaki TRaction Control) was designed to prevent wheel spin that could otherwise cause the loss of control of the bike. Like ABS prevents wheels from locking up when braking, this Kawasaki-original traction control system prevents the rear tyre from slipping. Knowing that the system will intervene to prevent sudden wheel spin when, for example, the pavement comes to an abrupt end when touring, is a great source of reassurance for riders.
KTRC uses wheel speed sensors to monitor front and rear wheel speed. When it detects wheel spin, engine power is reduced to allow rear wheel grip to be regained. KTRC also enables helps the rear wheel regain traction in situations where grip is lost temporarily, like when riding over a wet manhole cover.
KTRC uses 3-way control, governing ignition timing, fuel volume and (via the sub-throttle valves) intake air volume. This 3-way control is what enables the system to be so smooth, resulting in a very natural feeling.
It is technologically possible for traction control systems to recover from loss of grip due to wheel spin without the rider ever realising that they had slipped. However, KTRC lets riders know when road conditions are slippery by purposely delaying intervention for an instant. Firstly, communicating an accurate picture of current road conditions and what the bike is doing, and secondly, ensuring that systems provide support for riders – this is the philosophy that drives development of Kawasaki technology.
(Kawasaki TRaction Control)
3-mode KTRC combines the traction control technology of both 1-mode KTRC, which provides enhanced stability in slippery situations by preventing wheel slip, and S-KTRC, which helps maintain optimum traction in sport riding situations by predicting the rear wheel slip ratio during acceleration, into a single system.
The convenient handle switch allows the type of traction control to be changed by selecting one of the three modes, even while riding. Modes 1 and 2 maintain optimum traction during cornering, like S-KTRC. Designed with sport riding in mind, they enable sharp acceleration out of corners by maximising forward drive from the rear wheel. Modes 1 and 2 differ in the amount that they intervene. Mode 1, set for dry, good-grip road conditions, maintains the ideal slip ratio to ensure optimum traction.
Mode 3 operates like 1-mode KTRC, reducing power to allow grip to be regained when rear wheel spin is detected. It is ideal when riding in slippery conditions or in the wet. Enabling riders to easily change traction control character, 3-mode KTRC is Kawasaki's most advanced engine management system.
Models equipped with multiple Power Modes offer riders an easily selectable choice of engine power delivery to suit riding conditions or preference. In addition to Full Power mode, one (Low) or two (Medium, Low) alternate mode(s) in which maximum power is limited and throttle response is milder. Riders may opt to use Low Power mode for rainy conditions or city riding, and Full Power when sport riding. Power Modes may be set independently of traction control settings, enabling a number of possible combinations.

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 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 310 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, 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.

Launch Control Mode
In motocross racing, getting a good start is critical. A few tenths of a second can make the difference between getting the holeshot or not. In slippery conditions, getting the maximum drive from a motocrosser requires precise control of the both the clutch and throttle.
Launch Control Mode helps riders get a good start by complementing high-level technique with engine management. Featured on a mass-production motocross for the first time on Kawasaki's KX450F, the system activates a separate engine map designed to get a more efficient start off the line. The system is designed to the same specifications as that used by our factory racers competing in the AMA Supercross and Motocross championships.
Launch Control Mode is activated simply by pressing the button on the handlebar. The Launch Control map slightly retards ignition timing to help tame the engine's strong torque and reduce wheel spin off the start. Launch Control Mode is only active in the first two gears off the start, disengaging and returning to the standard engine map automatically once the rider shifts into 3rd gear. The system gives riders a great advantage when lining up at the gate and puts them in a better position to win.
Assist & Slipper Clutch
Based on feedback from racing activities, the Assist & Slipper Clutch uses two types of cams (an assist cam and a slipper cam) to either drive the clutch hub and operating plate together or apart.
Under normal operation, the assist cam functions as a self-servo mechanism, pulling the clutch hub and operating plate together to compress the clutch plates. This allows the total clutch spring load to be reduced, which translates to a lighter clutch lever feel when operating the clutch.
When excessive engine braking occurs – as a result of quick downshifts (or an accidental downshift) – the slipper cam comes into play, forcing the clutch hub and operating plate apart. This relieves pressure on the clutch plates to reduce back-torque and help prevent the rear tyre from hopping and skidding. This race-style function is particularly useful when sport or track riding.

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 is anything but gentle and often more than the rider can handle. Dual throttle valve technology was designed to tame engine response while contributing to performance.
On most fuel injected models, throttle bodies have only one throttle valve per cylinder. 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 in improved and power is increased.
Like other Kawasaki engine management technology, Dual Throttle Valves were designed with the philosophy of "following the rider's intention, while providing natural-feeling support." They are featured on many Kawasaki models.

Kawasaki's KX250F was the first mass-production motocrosser to feature Dual Injectors. One injector is located downstream of the throttle valve, where injectors are located on standard FI systems, and a second is located upstream of the throttle valve, close to the airbox. The two injectors split their roles: operating at different rpm ranges, they ensure both smooth, instant response at low-rpm and high peak power at high-rpm.
For cases that call for low-rpm operation like instantaneous acceleration off the start and precise control when cornering, primary operation falls to the downstream injector. Because it is positioned close to the combustion chamber, sprayed fuel can be supplied to the engine quickly, resulting in sharp response. Conversely, when high power is the priority, primary operation switches to the upstream injector, which focuses on high-rpm applications. Its location farther away from the combustion chamber means that the fuel has a longer travel time. This allows more time for the fuel particles and air to mix, as well as allowing the mixture to cool and condense. This means that when more power is needed, the cylinder can be filled with a greater quantity of high-quality mixture.
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.

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.

Kawasaki has long had a reputation for building great sounding bikes - a characteristic inherent in Kawasaki's engine architecture - but it is only recently that effort has been put into crafting a specific auditory experience though careful sound tuning of either the intake or exhaust system. Designed specifically to allow riders to enjoy their motorcycles aurally as well as physically, the carefully crafted auditory notes can be the key components of the street riding exhilaration offered by models that have benefited from sound tuning. Sound tuning can include conducting sound research, designing intake and exhaust system components based on acoustic test carried out in a sound room, and careful consideration of every detail of a system's components to ensure a balance of performance and the desired sound.
