[0002] As a mobile and flexible means of transportation, motorcycles have brought great convenience to people's lives. Motorcycles are small, light and flexible, so they are widely used in life. As the noise limit standards for motorcycles become increasingly stringent, motorcycles need to undergo noise tests before leaving the factory. At present, the European motorcycle acceleration noise test method is ECE R41, which is different from the national standard acceleration noise test method. It requires the motorcycle to operate as follows during the test: When the front of the motorcycle passes the test starting line, the throttle control must be adjusted to a position as soon as possible (half-open throttle, full-open throttle or maintain the current throttle position). In order to more accurately reflect the throttle state of the motorcycle during the test, it is necessary to monitor the throttle opening. However, the existing throttle position opening is transmitted to the ECU inside the motorcycle, and external testers cannot view it, so the throttle opening state cannot be monitored in real time.

[0003] Therefore, there is an urgent need for an external monitoring and display device for the throttle opening of a motorcycle with a simple structure and reasonable design to realize external monitoring and display of the throttle opening, so that testers can obtain the throttle opening during motorcycle testing and meet motorcycle testing requirements.
