This seat bench is installed as an original part on the base version of the Vespa Primavera 125 E5+ (2024-2025), but also fits all other Primavera and Sprint models.
The seat benches of the Primavera/Sprint 125/150cc models can be swapped with each other; however, they do not fit the 50cc models due to the electric seat unlocking mechanism.
Conversely, the seats of the 50cc models do not fit the 125/150cc models due to the manual seat unlocking (using a lock and key) but can be swapped freely between Primavera 50cc and Sprint 50cc models.
