The CVT gearing system encompasses two parts, the Variator at the front, driven by the crank and the Torque Driver at the rear, connected to the clutch and then the rear wheel.

The operation of the faces is a little different than on the variator.

 

Trial and error might be the best or the only way to judge.

 

This is a stage really only recommended for liquid cooled scooters.

 

Likewise to take this step further with race level cylinder kits and cranks — other parts such as the transmission and carb should also be upgraded to get the full performance from the race level motor.

 

Which one is best depends on the scooter, the power of the engine, the gear ratios, the design of the variator, the weight of the rider and what you want from the scooter maximum economy, maximum performance.

 

The driven pulley is tunable.

 

Different exhausts are available for different scooters, however for most makes and models the Arrow Street and Extreme exhausts are quite appropriate.
