Unlock the full potential of your engine with the NCY Super Transmission Set. This "new and improved" bolt-on kit is engineered to deliver lightning-fast acceleration, higher top-end speeds, and a significantly smoother powerband. Whether you are daily commuting on a Genuine Buddy 125/150/170i or tuning a custom GY6 150cc to 232cc build, this kit is the gold standard for CVT performance.

This Super Trans Kit is one of the best dollar-for-dollar bolt-ons to improve your bike! Quicker acceleration, higher top speeds, and makes your CVT the smoothest operating trans in town! From rapid downshifting to slow cruising, this thing is smooth. Ultralight balanced components, oversized wear pads, and state of the art polytetrafluoroethylene (PTFE) coatings ensure superior performance and long service life.

NCY utilizes state-of-the-art friction-reducing coatings and ultralight-balanced components to minimize rotational mass, resulting in rapid downshifting and improved throttle response across all RPM ranges.
