The rider can choose from three engine power modes to suit their preferences and road conditions.
The FI ECU controls the engine power by adjusting fuel injection, air intake, and ignition timing. It enables three-mode selection: Full Power (Mode F), Middle Power (Mode M), and Low Power (Mode L).
In addition, combining each mode with each S-KTRC setting allows the rider to have more choices to be able to interact with various conditions.

Power Mode Operation
To change the mode, close the throttle grip completely,
and depress the power mode button [A] (0.3
0.4 sec.).

Power Mode Positions

NOTE
The power mode setting is maintained when the ignition switch is turned OFF, or when the battery is disconnected.
Mode F: The highest engine power output is achieved. The rider can use the full power of the engine.
Mode M: The throttle response is less sharp compared to mode F. Depending on the throttle application, full power can be accessed temporarily.
Mode L: About 60% of the highest engine power output is achieved. The throttle response is mildest among the three modes.

The current mode selection is displayed on the power mode indicator [A] in the multifunction meter.
If a failure occurs with a FI related components such as a subthrottle or main throttle sensor, the warning indicator light (red LED) and FI warning symbol will go ON, and/or the S-KTRC indicator [B] and warning indicator light (yellow LED) [C] blink. The current mode cannot be changed at this time.
