Honda CBR125RW - Owner's Manual > Bank Angle Sensor Ignition Cut-off System

Your motorcycle's banking (lean angle) sensor system is designed to automatically stop the engine and fuel pump if the motorcycle is overturned.

Before restarting the engine, you must turn the ignition switch to the OFF position and then back to ON. The engine will not restart until you perform this procedure.

How to Stop the Engine

Normal Engine Stop

To stop the engine, shift into neutral and turn the ignition switch OFF.

The engine stop switch should normally remain in the RUN position even when the engine is OFF.

If your motorcycle is stopped with the engine stop switch OFF and the ignition switch ON, the headlight and taillight will remain on, resulting in battery discharge.

Emergency Engine Stop

To stop the engine in an emergency, use the engine stop switch. To operate, press the switch to the OFF position.

Shifting Gears

Your motorcycle has six forward gears in a one-down, five-up shift pattern which is coordinated with a cable-operated clutch system.

Learning when to shift gears comes with experience. Keep the following tips in mind:

• As a general rule, shift while moving in a straight line.
• Close the throttle and pull the clutch lever in completely before shifting.

  Improper shifting may damage the engine, transmission, and drive train.

• Learn to recognize the engagement point as you release the clutch lever. It is at this point the transmission of power to the rear wheel resumes.
• Upshift to a higher gear or reduce throttle before engine rpm (speed) gets too high. Learn the relationship between engine sound and the normal shifting points.
• Downshift to a lower gear before you feel the engine laboring (lugging) at low rpm.
• Avoid downshifting to help slow your motorcycle when engine rpm is near its allowable maximum (near the tachometer red zone). In this situation, the rev limiter in the engine ignition control module may not prevent excessive engine speed which could damage the engine.
• To prevent transmission damage, do not coast or tow the motorcycle for long distances with the engine off.

Recommended Shift Points

Ride in the highest gear that lets the engine run and accelerate smoothly. This will give you good fuel economy and effective emissions control. When changing gears under normal conditions, use these recommended shift points:

Shifting Up:

From 1st to 2nd: 20 km/h (12 mph)
From 2nd to 3rd: 30 km/h (19 mph)
From 3rd to 4th: 40 km/h (25 mph)
From 4th to 5th: 50 km/h (31 mph)
From 5th to 6th: 60 km/h (37 mph)

Shifting Down:

From 6th to 5th: 45 km/h (28 mph)
From 5th to 4th: 35 km/h (22 mph)
From 4th to 3rd: 25 km/h (16 mph)

Pull the clutch lever in when speed drops below 15 km/h (9 mph), when engine roughness is evident, or when engine stalling is imminent; and shift down to 1st gear for acceleration.
