KCMF - Kawasaki Cornering Management Function
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. KCMF oversees the following systems (where available): KTRC (including traction, wheelie and sliding control)KIBS (including pitching control), Kawasaki Engine Brake Control

IMU - Inertial Measurement Unit
IMU means Enhanced Chassis Orientation Awareness. The strength of Kawasaki's cutting-edge electronics has always been the highly sophisticated programming that, using minimal hardware, gives the ECU an accurate real-time picture of what the chassis is doing. Kawasaki's proprietary dynamic modelling program makes skillful use of the magic formula tyre model as it examines changes in multiple parameters, enabling it to take into account changing road and tyre conditions. The addition of an IMU (Inertial Measurement Unit) enables inertia along 6 DOF (degrees of freedom) to be monitored. Acceleration along longitudinal, transverse and vertical axes, plus roll rate and pitch rate are measured. The yaw rate is calculated by the ECU. This additional feedback contributes to an even clearer real-time picture of chassis orientation, enabling even more precise management for control at the limit. With the addition of the IMU and the latest evolution of Kawasaki's advanced modelling software, Kawasaki's electronic engine and chassis management technology takes the step to the next level changing from setting-type and reaction-type systems to feedback-type systems to deliver even greater levels of riding excitement.

Power Modes
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 (Middle, Low) alternate mode(s) in which maximum power is limited and throttle response is milder are provided.

Smartphone Connectivity
Clever technology enables riders to connect to their motorcycle wirelessly. Using the smartphone application RIDEOLOGY THE APP a number of instrument functions can be accessed, contributing to an enhanced motorcycling experience. Vehicle information (such as the odometer, fuel gauge, maintenance schedule, etc) can be viewed on the smartphone. Riding logs (varies by model, but may include GPS route, gear position, rpm, and other information) can be viewed on the smartphone. When connected, telephone (call, mail) notices are displayed on the instrument panel. Riders can also make changes to their motorcycle instrument display settings (preferred units, clock and date setting, etc) via the smartphone. And on certain models, it is even possible to check and adjust vehicle settings (such as Rider Mode, electronic rider support features, and payload settings) using the smartphone.

KTRC (3-mode)
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 instantly 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 maximizing 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.

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, resulting in 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 helps prevent the rear tyre from hopping and skidding. This race-style function is particularly useful when sport or track riding.

KQS - Kawasaki Quick Shifter
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. On models that offer clutchless downshifts, during deceleration the system automatically controls engine speed so that the next lower gear can be selected without operating the clutch.

Horizontal Back-link Rear Suspension
Compared to Kawasaki's traditional Uni-Trak rear suspension, which mounts the shock unit vertically, with Horizontal Back-link rear suspension, the shock unit is almost horizontal. Kawasaki's original suspension arrangement locates the shock unit very close to the bike's centre of gravity, greatly contributing to mass centralisation. And because there is no linkage or shock unit protruding beneath the swingarm, this frees up space for a larger exhaust pre-chamber (an exhaust expansion chamber situated just upstream of the silencer). With a larger pre-chamber, silencer volume can be reduced, and heavy exhaust components can be concentrated closer to the centre of the bike, further contributing to mass centralisation. The result is greatly improved handling. Another benefit is that the shock unit is placed far away from exhaust heat. Because it is more difficult for heat from the exhaust system to adversely affect suspension oil and gas pressure, suspension performance is more stable. Horizontal Back-link rear suspension offers numerous secondary benefits like this.

Sound Tuning
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 benefitted 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.

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 Electronic Cruise Control.

Electronic Cruise Control
Electronic Cruise Control allows a desired speed (engine rpm) to be maintained with the simple press of a button. Once activated, the rider does not have to constantly apply the throttle. This reduces stress on the right hand when travelling long distances, enabling relaxed cruising and contributing to a high level of riding comfort.

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.

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.

ABS
Sudden over-application of the brakes, or braking on low-grip surfaces (surfaces with a low coefficient of friction) such as wet asphalt or manhole covers may cause a motorcycle's wheel(s) to lock up and slip. ABS was developed to prevent such incidents. Kawasaki ABS systems are controlled by high precision and highly reliable programming formulated based on thorough testing of numerous riding situations. By ensuring stable braking performance, they offer rider reassurance that contributes to greater riding enjoyment. And to meet the special requirements of certain riders, specialised ABS systems are also available. For example, KIBS (Kawasaki Intelligent anti-lock Brake System) is a high-precision brake system designed specifically for supersport models, enabling sport riding to be enjoyed by a wider range of riders. And by linking the front and rear brakes, K-ACT (Kawasaki Advanced Coactive-braking Technology) ABS provides the confidence to enjoy touring on heavyweight models. Kawasaki is continually working on the development of other advanced ABS systems.
