Model: Sym Jet X 125
Part: Drivetrain

To replace the transmission on the Sym Jet X 125, you need to loosen the bolts securing the cover located near the rear wheel on the left side of the scooter. Once the cover bolts are removed, you can detach the cover and access the underlying components. The central nut securing the variator and the one securing the clutch can be loosened, allowing you to remove both components along with the corresponding belt around them. This way, you can install the new replacement parts, reassembling all the removed components.
