{"product_id":"tfc-forged-aluminum-performance-variator-kit-gy6-125-170cc","title":"TFC Forged Aluminum Performance Variator Kit - GY6 125-170cc","description":"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.
