Description
If you are looking for more power for your 4-stroke 50cc Piaggio Vespa scooter: Polini Cylinder Aluminium 79cc d.49mm Piaggio / Vespa 50cc 4-stroke.
Polini developed some tuning products to boost the performance of 3V iGET ie Euro 3 engines, among them is this aluminum cylinder. Polini recommends the use of the ECU module (P171.0007) and the Hi-Speed CVT (U241.737), both also designed for this type of engine, to get power up to 88 km/h. If you also use Polini's secondary gear kit 14/43 (P202.1414), your Vespa will probably be among the best-equipped scooters ever.
You can expect excellent workmanship and fantastic performance with increased torque from this "Made in Italy" product. Due to the increased displacement (79cc), it provides better acceleration and slightly higher top speed. And as it is made of aluminium, cooling properties are outstanding.
We recommend combining this cylinder with a sports exhaust.

The service life of a cylinder depends on whether it has been fitted correctly.
Tuning Level: Sport
We categorize our products into different performance levels Original, Sport, Racing and High End , so that our customers can choose the right parts for their setup. It is really important to combine parts that belong to the same tuning level, this is especially true for cylinders, crankshafts and exhausts.
The products listed under Sport yield better performance than Original parts. They may have technical differences, such as the use of higher quality materials, a larger displacement or a performance-enhancing design. They are suitable for everyday use and have a long service life.
Aluminium cylinders
Aluminium cylinders are more powerful than cast iron cylinders, but require more regular maintenance and must be combined with different components such as a reinforced crankshaft and a larger carburetor.
How to run in an aluminium cylinder?
Aluminium cylinders should be run in for about 200 kilometers , and you should use a fully synthetic engine oil.
