RMS Torque Drive Pulley (mobile) Vespa ET4 \/ LX 50cc

RMS, Italy, is a prolific manufacturer of OEM quality aftermarket parts for many scooter brands, including Vespa Vintage and Vespa Modern parts.

Torque drives are an important part in a continuously variable transmission (CVT). The driven pulley itself is made up out of two halves, one is sitting on the output shaft of the variator in a fixed position, the other is moving. The more rpm, the more centrifugal force and the greater the travel distance between the two halves.

The RMS Torque Drive Pulley (mobile) Vespa ET2 \/ ET4 \/ LX \/ LXV \/ S 50cc is an OEM quality pulley, basically identical to the original part and ideally suited to replace it.
Gasket is included.
