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.
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.
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.
