Upgrade your entire rear CVT driven assembly with the RDLN Racing Clutch Kit with Adjustable Sheave Pulley (1200-1275) for 139QMB and GY6 50cc engines. This complete kit replaces the stock clutch with a performance-engineered unit designed for rapid, reliable engagement and customizable acceleration tuning.
Includes three components: the clutch shoe assembly with red reinforced friction plates and 1500rpm engagement springs; the red anodized vented clutch bell/drum with large tapered vents and splined center bore; and the adjustable six-groove sheave pulley (three straight ramps for quicker off-the-line takeoff, three curved ramps for higher top speed). Cross-drilled holes and tapered vents on the outer drive face enhance heat dissipation under hard use.
This product is intended for off-road use only. This product is not intended for use on public roads or land.
If your 50cc�100cc engine code contains "QM" or "FM" it is likely compatible with this kit.
