The TFC Performance Variator Set is a premium, race-grade transmission upgrade for 125cc to 170cc GY6 engines. Engineered in Taiwan, this kit replaces your heavy stock front pulley with a lightweight, forged aluminum assembly designed to reduce rotational mass and significantly improve throttle response.
The variator features a specialized PTFE coating to minimize roller friction and heat, while the CNC-machined grooved sidewalls increase airflow to keep your CVT belt running cooler for longer. This kit is "tuner-ready," including three different sets of roller weights so you can perfectly balance your scooter for off-the-line torque or maximum top-end speed.
Performance Kit Includes:
- Forged Aluminum Variator: Features sidewall cooling grooves and a Red Teflon friction-reduction coating.
- CNC Drive Face: Lightweight, forged aluminum with a high-polish multicolor finish.
- 3 Sets of Roller Weights: Includes 10g, 11g, and 12g rollers for precision tuning.
- 15% Stiffer Torque Spring: Increases belt tension to prevent slippage during hard acceleration.
- Installation Hardware: Includes forged ramp plate, sliders, 14mm aluminum nut, and washers.
Technical Specifications:
- Material: CNC-Machined Forged Aluminum
- Engine Type: GY6 4-Stroke (125cc / 150cc / 170cc)
- Spline Count: Standard 19-Spline GY6 Crankshaft
- Origin: Made in Taiwan
Tech Tip: For the best results, start with the 11g "middle" weights. If you want more hill-climbing power, switch to the 10g rollers. If you want lower cruising RPMs and more top speed, use the 12g rollers. Always use a calibrated torque wrench for the 14mm variator nut.
