S-KTRC

(Sport-Kawasaki TRaction Control)

S-KTRC (Sport-Kawasaki TRaction Control), Kawasaki's original predictive traction control, uses the same base technology as the Kawasaki works machines that competed in MotoGP, the pinnacle of motorcycle racing. 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 (usually between 20-30% slip ratio, i.e. the rear wheel is turning 20-30% faster than the front). 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, engine rpm and throttle position. 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 interpolate and predict how the bike will behave in the next instant.

Unlike 1-mode KTRC, which cuts power as soon as rear slip is detected to allow rear traction to be regained, S-KTRC uses minimal power drops to ensure the slip ratio for optimal traction is maintained. Because its goal is to maximise acceleration, as long as sufficient forward motion is observed, this sport riding system will allow power wheelies as the bike comes out of corners.
