The TFC Racing variator is an aftermarket performance part for CVT (Continuously Variable Transmission) systems on scooters equipped with a GY6 125cc to 150cc engine, such as the Honda Ruckus GY6, Sym, PGO, Kymco, etc.
The variator is part of the primary transmission system that connects the engine to the drive belt. It automatically adjusts the gear ratio based on engine speed and the centrifugal forces exerted by the rollers/pulleys. A good variator allows you to:
Optimize acceleration
Improve smooth acceleration
Maximize top speed (depending on the setting)
Reduce energy losses in the transmission
The TFC Racing stands out thanks to its reinforced construction, tight machining tolerances, and a design optimized for sport or tuning applications (performance exhaust, optimized intake, cylinder kit, etc.). It is balanced to limit vibrations and improve the lifespan of transmission components.
