Primary Drive Rear Pulley Shaft for Yamaha XMAX 300 B74-E6111-00
Restore smooth power delivery to your scooter’s continuously variable transmission with this direct-fit Primary Drive Rear Pulley Shaft, engineered to replace OEM reference B74-E6111-00 on the Yamaha XMAX 300. The rear pulley housing protects and guides the drive belt as engine RPM shifts, so even minor wear here causes hesitation, delayed acceleration, or uneven gear changes. Replacing this worn component returns crisp throttle response and prevents costly secondary damage to the drive belt, rollers, and front clutch assembly.
Key Benefits & Installation Tips
- This straightforward swap revives lost top-end speed and reduces transmission slippage without requiring a full CVT rebuild.
- Always inspect the drive belt and rollers during replacement; pairing new moving parts with a fresh shaft extends overall service life.
- The design follows factory geometry for bolt-on compatibility, making it accessible for both garage mechanics and DIY riders.
