{"product_id":"ncy-super-transmission-kit-honda-ruckus-metropolitan","title":"NCY Super Transmission Kit - Honda Ruckus\/Metropolitan","description":"Eliminate the factory bottlenecks and unlock your engine's true potential with the NCY Super Transmission Set . This isn't just a single part—it is a comprehensive re-engineering of your scooter's Continuously Variable Transmission (CVT). By replacing your restrictive stock components with NCY’s precision-machined racing gear, you achieve smoother power delivery, snappier throttle response, and a significant increase in top-end speed—often gaining 3-5 MPH on an otherwise stock 50cc engine. What’s Inside the Kit? Performance Variator: Features optimized roller ramps and a larger diameter to allow the belt to travel higher, effectively giving you a \"taller\" top gear. Ultralight Drive Face: Reduces rotating mass on the crankshaft, allowing the engine to rev into its powerband faster for superior acceleration. 3 Sets of 16x13mm Roller Weights: Includes 3 weight sets designed to balance low-end \"snap\" with high-end velocity based upon your preference. Adjustable Sheave Clutch Pulley: An adjustable torque driver improves takeoff power (quicker acceleration) and optimizes top-end speed by managing belt position. 1000 RPM Torque Spring : high-tension compression spring eliminates belt slip and provides consistent back-shifting during hill climbs.
