What does a motorcycle's throttle control?

The throttle of a motorcycle is primarily responsible for controlling the bike's speed and acceleration. When a rider twists the throttle (usually located on the right handlebar), it opens a valve that allows more air and fuel to enter the engine. This increase in the airflow increases engine RPMs (revolutions per minute) and subsequently boosts the bike's speed. The more the throttle is opened, the faster the motorcycle accelerates. This mechanism plays a crucial role in how riders manage their speed and responsiveness while riding.

While braking power is controlled by the brake lever or pedal, navigation systems operate independently and typically involve GPS or other electronic systems. Fuel efficiency is impacted by various factors, such as riding style and engine management, but it is not directly controlled by the throttle itself. Thus, the throttle's primary function is indeed to manage the motorcycle’s speed and acceleration.
