Kawasaki
Technology Engine management

Ever since our first motorcycle engine in 1950, Kawasaki has been continually pursuing new technologies in the creation of our high-performance engines. Today, our models are filled with numerous original Kawasaki technological features that have evolved over our long history.

S-KTRC

S-KTRC (Sport-Kawasaki TRaction Control) is a racing technology-based predictive traction control system designed to help riders push harder on the racetrack by maximising acceleration.

S-KTRC, Kawasaki's original predictive traction control, uses the same base technology as Kawasaki’s works machines. Designed to maximise acceleration, it allows riding at the edge of traction on the track. This technology continually controls the rear wheel slip that occurs when power is applied, ensuring optimal acceleration. In general, maximum forward drive requires a certain amount of slip. To ensure the most effective transfer of power to the tarmac, S-KTRC monitors the slip ratio in real time, and governs engine power delivery to optimise rear wheel traction.
S-KTRC monitors a number of parameters, including front and rear wheel speed (slip), engine rpm, throttle position and acceleration. Conditions are confirmed every 5 milliseconds, at which time the system looks at each of the parameters as well has how much they are changing (i.e. their rate of change). This unique Kawasaki method makes it possible to make interpolations and precisely calibrate engine output to suit traction conditions. By acting before slippage exceeds the limits of traction, drops in power can be minimised, resulting in ultra-smooth operation.
Because the 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. It also automatically adjusts for tyre wear, different tyre profiles, high-grip tyres, and numerous other factors that setting-type systems treat as fixed parameters. Models equipped with IMU incorporate chassis-orientation feedback to offer even more precise management.
