APPLICATION Biz 125 2011 2012 2013 2014 2015

Made of Metal: The throttle assembly is typically made of aluminum alloy or other metallic materials to ensure its durability and ability to withstand the high temperatures and pressures of the engine.

Throttle: The throttle is the main part of the throttle assembly and controls the amount of air intake into the engine. It can be adjusted by operating the accelerator pedal to control engine speed and power output.

Sensor: The throttle assembly usually integrates some sensors, such as a throttle position sensor, etc., to monitor the position of the throttle and provide feedback information to the vehicle's electronic control unit (ECU).


Intake duct: The throttle assembly also includes a part connected to the engine's intake duct to ensure that air can flow into the engine smoothly and the intake air volume can be accurately controlled when needed.

The throttle assembly of a motorcycle adjusts the amount of air intake by controlling the position of the accelerator pedal, thereby controlling the engine speed and power output. This is because the throttle assembly is located in the intake tract, and when the gas pedal is operated, it opens or closes to control the amount of air flowing into the engine.

By adjusting the position of the throttle, the motorcycle rider can control the degree of acceleration and deceleration, giving the motorcycle better handling performance and fuel economy. The throttle assembly is also connected to the vehicle's electronic control unit (ECU), which uses sensor feedback information to enable the ECU to make precise adjustments according to different driving conditions and needs.
