Application:The Motorcycle Driven Pulley is a critical component of a scooter or motorcycle’s Continuously Variable Transmission (CVT) system. It is the secondary pulley located on the transmission input shaft, responsible for transferring power from the drive belt to the gearbox and ultimately to the wheel. Its key function is to vary its effective diameter based on engine RPM and riding conditions, working in tandem with the drive pulley to provide seamless, automatic gear ratio changes for optimal acceleration and fuel efficiency.
