Product Description
Maximum Durability: Gates Super Premium Reinforced Belt
Upgrade your transmission’s reliability with the Gates Super Premium CVT Drive Belt. Engineered for high-load applications, this belt is constructed with specialized EPDM rubber compounds and high-tensile cords to resist the heat and stretching that lead to "belt snap" in tuned GY6 engines. Whether you are commuting or pushing a big-bore kit, Gates provides the consistent grip and power transfer required for peak performance.
Technical Performance Features
- Advanced EPDM Construction: Designed to withstand extreme transmission temperatures, significantly extending service life compared to standard chloroprene belts.
- High-Tensile Cords: Minimizes belt stretch during hard acceleration, ensuring your variator and clutch stay in the optimal power band.
- Precision Cog Profile: Optimized for GY6 150cc pulleys to reduce internal friction and noise while maximizing airflow within the CVT case.
- Vento Phantom Optimized: The exact factory-spec upgrade for the Vento Phantom series, providing a smoother ride and better top-end stability.

Mechanic's Note: This "842" belt is designed specifically for Long Case engines. If your scooter has a 12-inch or 13-inch rear wheel, this is likely your belt. If you have a 10-inch wheel, you likely need the shorter 743-20-30 belt. Always check your engine code (located near the rear shock mount) to confirm compatibility.
