Description
Unlock the hidden speed of your 50cc engine with the NCY Performance Variator. The factory variator is designed for fuel economy and restricted top speeds; NCY re-engineered this component with optimized roller ramps and a larger diameter to allow your CVT belt to travel higher and faster. This results in quicker off-the-line takeoffs and an increase in top-end speed, often gaining 3-5 MPH on an otherwise stock scooter.
Key Performance Benefits
- Extended Roller Ramps: Precision-machined ramps allow the roller weights to move further outward, pushing the belt to a higher “gear ratio” for increased top speed.
- Ultralight Aluminum Alloy: Reduces rotating mass compared to the heavy stock unit, allowing the engine to reach its powerband faster for snappier throttle response.
- Enhanced Cooling: Features a finned design that dissipates heat more efficiently, preventing belt slip and power fade during long summer rides.
- Plug-and-Play Upgrade: Designed to fit directly onto the crankshaft without modification—compatible with stock or performance roller weights.
