Piaggio OEM Roller Weight for Vespa 150 / Fly / Liberty / 946 B019236

Replacement Roller Weight for Vespa and Piaggio Scooters

This genuine OEM roller weight is made for current Vespa and Piaggio scooters, such as the Vespa 150, Fly, Liberty, and 946 models. It targets slow pickup and uneven gear changes that come from worn variator roller weights. Like other Vespa scooter parts, it fits in the spot the old weight occupied and brings performance back to factory specification.

Restoring Performance

Over time, flat spots can form on worn weights and cause acceleration to lag. Swapping in new weights improves throttle response and makes shifts through the gear ratios smoother. This part helps your scooter pull away as it did when it was new.

Build Overview

Each roller weight has a tough black nylon outer shell around a hollow metal core. The design reduces wear on the variator pulleys, and because the system runs more efficiently, the drive belt can last longer.
