TFC Racing Torque Driver Forged Aluminum RZR-170/GY6150

The TFC Racing Torque Driver Forged Aluminum is a high-performance upgrade designed for GY6-based 150cc (and compatible 125cc) CVT systems. It fits popular models including the Polaris RZR 170, RZR 200 (youth/mini models with GY6-style engines), many GY6 150cc scooters/ATVs/go-karts, and even adaptations for the Honda Navi (via GY6-compatible swaps or similar CVT setups—verify exact fitment for Navi as it's often a direct or close match in aftermarket communities).

Crafted from lightweight forged aluminum, this torque driver (also called secondary sliding sheave, rear pulley, or torque cam) delivers superior durability, reduced rotational mass, and better heat dissipation compared to stock cast pieces.

TFC is a trusted name in GY6 performance parts, known for quality forged components that hold up to aggressive riding—whether you're ripping around on a Polaris RZR 170 mini UTV, pushing a GY6 150 scooter to its limits, or modding a Honda Navi for more fun and zip.

Key Features & Benefits

• Adjustable Ramp Design: Features multiple groove/angle options (typically 2 settings) so you can tune for aggressive low-end acceleration (quicker takeoff from stops, better hill climbing, and snappier response) or balanced top-end speed—perfect for trail riding in the RZR 170/200 or street/scooter performance.
• Forged Aluminum Construction: Lighter than stock for faster engine rev-up and improved power transfer; stronger and more resistant to wear under high-rpm racing or heavy loads.
• Enhanced Performance: Expect noticeably quicker acceleration, reduced belt slip, smoother power delivery, and potential gains in both low-end torque and overall top speed when paired with matching variator/clutch upgrades.
• Precise Fit: Outer diameter ~142mm, compatible with standard GY6 125-150cc setups (157QMI/152QMI engines) found in the Polaris RZR 170/200 youth models, TaoTao/BSSR-style mini UTVs, Chinese GY6 scooters, and GY6-converted or similar Honda Navi applications.
• Easy Installation: Direct bolt-on replacement for the stock torque driver; includes or works with standard clutch nut, O-rings, and spring seat (full assembly often recommended).

Note: For the Honda Navi (110cc), confirm compatibility as it's not a native GY6 but shares CVT principles—many GY6 torque drivers are adapted successfully in the community. Professional installation recommended to ensure proper belt alignment and CVT tuning.
