The seats of the Primavera/Sprint 125/150cc models can be interchanged, but they do not fit the 50cc models due to the electric seat release mechanism.

Conversely, the seats of the 50cc models cannot be fitted to the 125/150cc models due to the manual seat release (using a lock and key), but they can be freely exchanged between Primavera 50cc and Sprint 50cc models.
