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 highly precise and extremely reliable programming formulated thorough testing of numerous riding situations. By ensuring stable braking performance, they offer rider reassurance for even greater riding enjoyment.
To meet the special requirements of certain riders, specialized ABS systems are also available. For example, KIBS (Kawasaki Intelligent anti-lock Brake System) is a precision-tuned brake system designed specifically for supersport models, enabling sport riding to be enjoyed by a wider range of riders. 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.
Developed and tested through Kawasaki Factory racing, the Assist & Slipper Clutch utilizes two types of cams. An assist cam and a slipper cam enable the Assist & Slipper Clutch to function in two different ways, with the clutch hub working together or apart from the operating plate.
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 feel at the lever.
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 tire from hopping and skidding.
Modern sportbikes often use large-bore throttle bodies to generate high levels of power. However, with large-diameter throttles, when a rider suddenly twists 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 enabling high performance.
On fuel-injected models, throttle bodies generally have only one throttle valve per cylinder. On models with dual throttle valves, there are two 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, controlled by the ECU, precisely regulates intake airflow to ensure a natural, linear response. With the air passing through the throttle bodies flowing smoothly, combustion efficiency is 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.
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.
Kawasaki developed KIBS to take into account the particular handling characteristics of supersport motorcycles, ensuring highly efficient braking with minimal intrusion during aggressive sport riding. It is the first mass-production brake system to link the ABS ECU (Electronic Control Unit) and engine ECU.
In addition to front and rear wheel speed, KIBS monitors hydraulic pressure of the front brake caliper(s), throttle position, engine speed, clutch actuation and gear position. This diverse information is analyzed to determine the ideal hydraulic pressure for the front brake. Through precise control, the large drops in hydraulic pressure seen on standard ABS systems can be avoided. Additionally, the tendency for the rear wheel of supersport models to lift under heavy braking can be suppressed, allowing the rider to maintain control of the rear brake when downshifting.
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 (or when a race kit ECU is used), clutchless downshifts are also possible.
Power modes offer riders an easily selectable choice between Full and Low Power. While Full Power is unrestricted, in Low Power mode, maximum power is limited to approximately 75-80% of Full. Throttle response is also milder in Low Power mode. Riders may opt to use Low Power mode for rainy conditions or city riding, and Full Power when sport riding.
Available on the Ninja® ZX™-14R / ZZR1400, Versys® 1000 and other Kawasaki models, when combined with the 3-mode KTRC (+ OFF) Traction Control system, Power Mode selection offers a total of eight combinations (KTRC: Mode 1/2/3/+OFF x Power Mode: Full/Low) to suit a wide range of riding situations. For example, an experienced rider enjoying sport riding on dry pavement might choose Full Power and Mode 1. On a wet or slippery surface, choosing Low Power and Mode 3 would yield the lowest chance of incurring wheel-spin, and the milder throttle response would offer a higher level of riding safety.
KTRC, Kawasaki's advanced traction control system provides both enhanced sport riding performance and the peace of mind to negotiate slippery surfaces with confidence. Multiple rider-selectable modes (the number of modes varies by model) offer progressively greater levels of intrusion to suit the riding situation and rider preference.
Less intrusive modes maintain optimum traction during cornering. Designed with sport riding in mind, they facilitate acceleration out of corners by maximizing forward drive from the rear wheel. And because Kawasaki’s sophisticated software bases its dynamic analysis on the chassis’ orientation relative to the track surface (rather than relative to a horizontal plane), it is able to take into account corner camber, gradient, etc., and adapt accordingly.
In the more intrusive modes (and for some models, in any mode), when excessive wheel spin is detected, engine output is reduced to allow grip to be regained, effectively enabling riders to negotiate both short, slippery patches (train tracks or manhole covers) and extended stretches of bad roads (wet pavement, cobblestone, gravel) with confidence.
Models equipped with IMU incorporate chassis-orientation feedback to offer even more precise management.
