Piaggio Vespa Primary Drive Spring (Inner) PX, T5, Cosa, , GS, SS, Rally
The spring is fitted to the inside of the primary drive gear and the Cluster. When fitting them, you will need to compress them slightly to fit them, this can be done with pliers and a screwdriver!
The primary drive springs do sometimes break, and will need changing asap! The springs take a lot of hammer, especially when the rider is heavy on gear changing (up and down shifting).
These products are available in a primary drive repair kit or as individuals! Some models will fit only larger springs, rather than the smaller springs.
