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.

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
Mode-switchingCoolant Level Inspection
Situate the motorcycle so that it is
perpendicular to the ground.
Check the coolant level through the
coolant level gauge on the reserve
tank located to the left of the engine.
The coolant level should be between
the “F” (Full) and “L” (Low) level lines.

Battery
The battery installed in this motorcycle
is a sealed type, so it is not necessary
to check the battery electrolyte
level or add distilled water.
The sealing strip should not be pulled
off once the specified electrolyte has
been installed in the battery for initial
service.
However, in or ...
Front Brake Pad Installation
Check that the pad spring [A] is in place on the caliper.
Push the caliper pistons in by hand as far as they will go.
Install the brake pads [A] on the pad spring correctly.
Fit the pad into the groove of the caliper as shown in the
figure.
Install the pad pins while pushing t ...
