The original Piaggio thermal group represents the ideal choice for your Gilera Runner 180cc FXR 2-stroke Maxiscooter, designed to ensure optimal performance and reliability. Made of aluminum, this cylinder features six transfers and an oval exhaust port, elements that contribute to efficient combustion and a quick engine response. The bi-segment piston, with a diameter of 65.6 mm and a pin of 16 mm, ensures perfect adaptability and smooth operation.
With a displacement of 180cc and a liquid cooling system, this thermal group is designed to offer excellent homologation and consistent performance over time. The spark plug thread is of the long M14 type, while the stroke is 52 mm, characteristics that align perfectly with the specifications of the original engine.
