The tilt angle sensor is a safety device that detects if the motorcycle is tilted too far or has fallen. It cuts off the fuel supply and shuts off the engine to prevent mechanical damage and reduce risks such as fires or unexpected movements. It works using gyroscopes, accelerometers, or mercury switches, sending a signal to the ECU when a critical angle is exceeded. Do not tamper with the sensor, check its operation with regular maintenance, start the motorcycle upright, check the cables, and ensure it continues to work after a fall. This way, you can ensure a safer and more reliable motorcycle.
