Long Description

This GY6125 rear driven pulley assembly is a core CVT transmission component specially designed for GY6 125cc scooter engines (152QMI). Made of high-strength aluminum alloy and thickened steel structure, it features excellent hardness, wear resistance and deformation resistance, adapting to long-term high-speed driving and frequent variable speed work.

The pulley surface is finely polished with smooth radian, which perfectly fits the transmission belt, effectively avoiding belt deviation, slipping and abnormal wear. Strict dimensional calibration ensures 100% matching with the original car position, realizing plug-and-play installation without drilling or cutting. It can effectively repair common faults such as powerless climbing, slow acceleration, noisy transmission and belt overheating caused by aging and worn original rear pulley. Stable transmission output brings smoother riding experience and longer service life of CVT accessories.
