Malossi Torque Drive Converter Disc – precise CVT tuning for Piaggio / Gilera (from year 1998), d=134 mm

The Malossi Torque Drive is a high-quality tuning converter disc for many scooters with Piaggio / Gilera engines (from model year 1998). Manufactured from extremely high-quality nitrided steel, it is designed for maximum durability and clean function in the variator drive.

The highlight: The modified slope of the guide grooves improves the shifting behavior – especially when used in conjunction with a sport variator. Particularly with more powerful setups, where the usable RPM range is often narrow, the Torque Drive helps you keep the variator better within the power RPM. Result: noticeably better acceleration and an additional, effective adjustment option for your CVT setup.

Fits many vehicles such as Vespa Primavera 50, Piaggio Zip 50 or Gilera Runner 50 – but also many other models from the Piaggio/Gilera/Aprilia environment.
