Vespa GTS/GTV/Super 300 OEM Roller (21x17 13.9g)

Genuine OEM Roller Weight for Vespa GTS, GTV, and Super Models

This genuine factory roller weight is made for Vespa scooters, namely the GTS, GTV, and Super models. It helps bring back factory-level acceleration, keeps gear changes smooth, and supports overall performance. Like many Vespa scooter parts supplied by the manufacturer, it installs directly in the spot the old roller came from, so it suits any maintenance or restoration job.

What the Roller Weight Does

This roller weight is used in the scooter's Continuously Variable Transmission (CVT). Each one is set to weigh 13.9 grams and measures 21mm across by 17mm wide. With regular riding, rollers gradually wear and develop flat spots, which can lead to uneven shifting, slow engine response, and vibration. Replacing them helps the scooter keep consistent performance and dependability.

Recommended Replacement Schedule

When you service the drive belt or reach the 6,000-mile service interval, it is best to replace all six roller weights at once. Doing this helps avoid performance problems and keeps the scooter running smoothly and efficiently.
