The seats of the Primavera/Sprint 125/150ccm models can be exchanged with each other, but due to the electric seat release, they do not fit on the 50ccm models.

Conversely, the seats of the 50ccm models do not fit on the 125/150ccm models due to the manual seat release (using a lock and key) but can be exchanged freely between Primavera 50ccm and Sprint 50ccm models.
