GY6 performance CVT transmission kit 125cc-170cc (2ND GENERATION)
This GY6 performance transmission kit is super easy to install. Bang for buck you will be blown away! this will increase your top speed, your acceleration, and it is much smoother than any stock GY6. Everything is lighter than stock in this kit (a must for performance). The clutch shoes are larger for more grip, the variator is teflon coated for durability, the clutch hub is built for max cooling, and the compression spring seat is upgraded to roller bearings (new design, check video above). All of this will give you a great experience that will last for many years.
