Stator Assembly for Vespa GTS 250/300 Models
This magneto stator assembly is designed for the Vespa GTS 250 and 300 models, providing a reliable solution for a failing electrical charging system. It is engineered to generate the necessary alternating current to power the ignition and recharge the battery while riding. As one of the most important Vespa scooter parts, it addresses issues like dim headlights and battery drain, ensuring a smooth riding experience even on high-mileage scooters.
Construction and Features
This stator assembly features high-grade thermal windings made from insulated copper wiring, capable of enduring high engine temperatures. Its optimized electrical generation is achieved through a laminated core that minimizes magnetic resistance, delivering stable current across all RPM ranges. The unit comes as an all-in-one kit with an integrated pulsar pickup coil and necessary wiring connectors, making installation straightforward.
Installation Guidelines
To install this stator assembly, you will need a specialized 35mm flywheel magneto puller tool to safely remove the flywheel. Attempting to use standard tools may damage the magnetic rotor or crankshaft. When replacing the stator, ensure to replace the crankcase gasket to avoid any oil and coolant leaks, as this part operates within the engine oil environment.
