The seats of the Primavera/Sprint 125/150cc models can be swapped with each other, but they do not fit the 50cc models due to the electric seat unlocking mechanism.

Conversely, the seats of the 50cc models cannot be used on the 125/150cc models due to the manual seat unlocking mechanism (with lock and key), but they can be swapped freely between Primavera 50cc and Sprint 50cc models.
