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.
When comparing 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 places the shock unit very close to the bike's center of gravity, greatly contributing to mass centralization. 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 center of the bike, further contributing to mass centralization. The overall 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 exhaust heat to adversely affect suspension oil and gas pressure, suspension performance is more consistent. Horizontal Back-link Rear Suspension offers numerous secondary benefits like this.
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’s 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.
