1. FI ECU

The FI ECU analyzes the motorcycle conditions based on the signals from the front/rear wheel rotation sensors and FI sensors (such as the crankshaft sensor and main throttle sensor), and controls engine power by reducing the number of ignition and retarding the ignition timing. The mode-switching signal is transmitted to the FI ECU by the CAN system via the meter ECU. If a failure occurs in the system, the FI ECU deactivates S-KTRC and displays the warning indication in the meter.

2. Wheel Rotation Sensor

The wheel rotation sensor converts front and rear wheel rotation speed to a pulse signal and transmits it to the FI ECU.

As for the KIBS (Kawasaki Intelligent anti-lock Brake System) equipped model, a pulse signal is transmitted via the KIBS ECU.

3. Crankshaft Sensor

The crankshaft sensor converts the engine speed to a pulse signal and transmits it to the FI ECU.

4. Main Throttle Sensor

The main throttle sensor converts the throttle position to a voltage signal and transmits it to the FI ECU.

Main Throttle Sensor


5. S-KTRC Button

The mode-switching signal is transmitted to the meter ECU by depressing the S-KTRC button (0.3 0.4 sec.).

6. Multifunction Meter

The multifunction meter receives a mode-switching signal and displays the mode [A], and transmits it to the FI ECU by the CAN system.

When a failure occurs in the system, themultifunction meter displays the warning indication by blinking the warning indicator light (yellow LED) [B] and mode indicator symbol.

It also displays the S-KTRC operating conditions in the level indicator [C].

7. KIBS ECU

As for the KIBS equipped model, the front and rear wheel sensor signals are transmitted to the FI ECU via the KIBS ECU.

Overview
S-KTRC is a highly sophisticated system based on MotoGP racing technology. Unlike the KTRC system used on the GTR1400 ABS (Concours 14 ABS in N. America), which is designed to offer rider reassu ...

Mode-switching
Depress the S-KTRC button on the left handlebar switch to change the mode. The mode can be changed only when the throttle grip is closed completely. The S-KTRC OFF can be selected only when the m ...
