GY6 125-170cc Variator Assembly for Scooters
This GY6 125-170cc OEM-style variator assembly is made to bring back smooth acceleration on your scooter. It arrives as a complete, ready-to-fit set that swaps out worn parts such as pulleys and rollers. It is one of the main GY6 150cc scooter parts you can use to keep performance strong. Whether your scooter is a Genuine Buddy or a common Chinese GY6 model, this direct-fit unit gives you factory-level function without paying dealer prices.
Complete Installation Kit
The assembly comes with everything required for a transmission refresh. The package contains a variator pulley, drive face, ramp plate, rollers, and drive boss. Every piece is machined for a precise fit, so no modifications are needed during installation.
Precision Engineering
Supplied with six 14g roller weights (18x14mm), this assembly is set up to balance torque and top speed for engines from 125cc to 170cc. The high-pressure cast aluminum body dissipates heat well, which helps reduce belt slippage and early wear.
