Assist & Slipper Clucth
Based on feedback from racing activities, the Assist & Slipper Clutch uses two types of cams (Assist Cam and Slipper Cam) to move the clutch hub and operating plate together or separately
In normal operation, the assist cam acts as a self-servo mechanism, pulling the clutch hub and operating plate together to compress the clutch plate. This reduces the total clutch spring load, resulting in a lighter clutch lever when operating the clutch.
When excessive engine braking occurs, the slipper cam comes into play as a result of rapid downshifts (or unintentional downshifts) forcing the clutch hub and operating plate apart. This reduces pressure on the clutch plate to reduce back torque and helps prevent the rear tire from jumping and skidding. This racing feature is very useful when sport riding or riding on the track
Business Management Technology
Economical Riding Indicator
Kawasaki motorcycles achieve fuel efficiency by using high levels of electronic engine management control. However, fuel consumption is also greatly affected by throttle use, gear selection, and other elements under the rider’s control. The Economical Riding indicator functions to indicate low fuel consumption conditions. The current system monitors fuel consumption, regardless of vehicle speed, engine speed, throttle position, and other riding conditions. When fuel consumption is low at a certain speed and fuel efficiency is high, the ‘ECO’ mark appears on the LCD screen of the instrument panel. If the rider can keep the ‘ECO’ mark lit, fuel consumption can be reduced.
Effective vehicle speed and engine speed may vary by model, but paying attention to the conditions that cause the ‘ECO’ mark to appear can help riders improve fuel efficiency – practical for long trips. In addition, maintaining low fuel consumption also helps minimize negative impacts on the environment.

ERGO - FIT
Proper Fit is key to rider comfort and control. However, the ideal size varies from rider to rider, depending on their physical dimensions and riding style. ERGO-FIT is an interface system designed to help riders find their ideal riding position. The various chassis interface points (handlebars, footpegs, seat, etc.) can be adjusted through a combination of replaceable parts and parts with adjustable positions. This allows a wide range of riders to find a comfortable and controlled riding position. Riders can not only feel at one with their machines, but also experience Kawasaki machines that are fun and rewarding to ride.
