Gates Premium CVT Drive Belt 835-20-30

Gates Premium 835-20-30 CVT Belt Upgrade your transmission with the gold standard of power delivery: the Gates Premium Power Link CVT Belt . Engineered specifically for high-stress motorized applications, this 835-20-30 belt is the go-to choice for street-legal 150cc scooters and off-road go-karts. While standard belts often fail under high heat, Gates utilizes advanced EPDM materials and high-strength internal cords to provide superior thermal resistance and longer service life. Technical Performance Features EPDM Compound Construction: Ethylene Propylene Diene Monomer (EPDM) offers unmatched heat resistance and flexibility, preventing the cracking and "chunking" common in cheaper neoprene belts. High-Tensile Poly Cords: Reinforced with heavy-duty internal cords that resist stretching, ensuring your gear ratios stay consistent and your top speed remains stable. Precision 30° Groove Angle: Optimized for the pulley faces of GY6 152QMI and 157QMJ engines, providing maximum grip and reducing power-robbing slippage. Consistent Performance: Designed to maintain its structural integrity across a wide range of operating temperatures, from cold morning starts to high-heat summer commuting. Comprehensive Fitment Guide This 835mm belt is the standard fit for "Long Case" GY6 125/150cc Engines and various specialty models: Brand / Category Compatible Models Vento Phantom R4i (Turbo), Phantom GT5, Xeidon 150, Phantera 150 Wolf Brand Blaze II, EX-150, V-150 Bintelli Bolt 150, Fury 150, Scorch 150 Go-Karts Hammerhead, TrailMaster, and most 150cc GY6 Buggies Technical Specifications Length: 835mm Top Width: 20mm Groove Angle: 30° Material: Premium EPDM / Poly Cord Mechanic's Note: The 835 size is very common for 150cc scooters with 12" or 13" rear wheels. If you are experiencing a "shudder" or loss of top speed, your belt likely has a flat spot or has stretched beyond its service limit. Pro Tip: When installing a high-performance Gates belt, check your Variator Slides for wear. A fresh belt works best when the pulleys can move freely and smoothly.
