NCY Champion CVT Full Transmission Kit with Extended Belt

Unleash the full potential of your Yamaha 155cc VVA engine with the ultimate transmission upgrade. Engineered and manufactured by NCY Motorsports in Taiwan, the Champion CVT Full Kit delivers a dramatic performance boost across the entire powerband. It is designed to transform your scooter from a standard commuter into a high-speed sport machine by eliminating factory restrictions and optimizing power transfer directly to the ground. Whether you are seeking snappy, immediate throttle response for urban overtaking or an extended top-speed ceiling for effortless highway cruising, this comprehensive, all-in-one kit provides everything required for a professional-grade transmission overhaul. Performance Upgrades and Features Significant Horsepower Boost: Increases maximum power from the stock factory baseline of approximately 11.5 PS up to a potent 13 PS. Experience a noticeable increase in acceleration and pulling power throughout the entire RPM range. Linear and Efficient Power Delivery: Provides a smoother, more stable power curve that eliminates the high-speed power fade common with OEM setups. This achieves the perfect balance between aggressive low-end acceleration and efficient long-distance cruising. Extended Top Speed Limit: Paired with the included +5mm extended CVT belt, this kit safely pushes the top speed ceiling from the factory limit of 118 km/h (approx. 73 mph) up to an incredible 140 km/h (approx. 87 mph). Important Configuration Notes Specialized Setup: The optimized top speed and acceleration curves are engineered specifically to work in tandem with the included +5mm extended belt. Utilizing standard-length or third-party belts will alter the performance profile and require separate transmission adjustments. Straight-Groove Driver: For maximum efficiency and performance longevity, the secondary sliding sheave is designed with a straight-groove configuration to deliver optimal back-shift response.
