GY6 125/150 Driven Spring
Sharper CVT Response. Improved Back-Torque Control. Four Tuning Options for GY6 Engines.
This Driven Spring for GY6 125/150 provides four tuning options to adjust acceleration response and back-torque behavior:
1000 RPM (Blue) — Slight upgrade from stock; smoother takeoff
1200 RPM (Orange) — Ideal balance for daily use
1500 RPM (Yellow) — Quicker acceleration with stronger preload
2000 RPM (Red) — Maximum tension for the fastest shift reaction
A stiffer driven spring stabilizes belt tension, reduces slip, and enhances CVT consistency—especially useful for upgraded cylinders, heavy-load riding, or frequent stop-and-go situations.
