Key Features

• Long-Case Optimization: Sized at 842mm, this belt is specifically designed for GY6 engines with the extended CVT housing, providing the correct tension required for 150cc configurations.
• High-Mileage Fiber-Rubber Blend: Constructed with a high-density fiber reinforcement that prevents stretching under load, allowing for consistent RPM transitions and a longer service life.
• Oil & Heat Resistant: Engineered to survive the harsh environment inside the belt cover, resisting chemical degradation from oil vapor and the high temperatures generated by the variator and clutch.
• 30-Degree Precision Angle: The teeth are cut at a precise 30-degree angle to ensure maximum surface contact with the pulley faces, preventing slipping and reducing power loss during take-off.
• Smooth Power Delivery: High-quality manufacturing standards ensure a vibration-free ride and quiet operation, even at high speeds or under heavy passenger loads.
