OEM-specification drive pulley assembly (variator) with an overall height of 147mm and a max outer diameter of 192mm. Designed for CFMoto 1000cc series ATV and UTV models, this is the core component of the CVT system, responsible for transmitting engine power to the drive belt.

This product is a genuine CF Moto drive pulley assembly (also known as the variator or driving pulley), part number 0JYA-051000-10002. This assembly is the core component of the CVT (Continuously Variable Transmission) system, mounted on the engine crankshaft. It contains rollers (weights) that use centrifugal force to change the pulley's effective diameter, enabling seamless ratio changes. This drive pulley assembly is manufactured from high-strength alloy materials and undergoes precision dynamic balancing to ensure smooth, efficient, and durable power transmission. Key dimensions: Overall Height 147mm, Max Outer Diameter φ192mm, Shaft Diameter φ13/29mm. Suitable for CVT system service or replacement on CFMoto 1000cc ATV and UTV models.
