Cylinder Polini Sport 70cc aerox
Sport 70cc cast iron cylinder from Polini for liquid-cooled horizontal Minarelli engines (Yamaha Aerox and many more). Strong performance in the low and mid RPM range, well-suited for everyday use.
The cylinder is made of cast iron, making it robust and reliable. With the right components (17.5mm carburetor, exhaust), it delivers around 8 - 9 hp. The wide powerband makes adjusting the variator weights relatively easy. Power is increased across the entire rev range, with noticeable improvement in takeoff and midrange — ideal for wheelie fans!
Note: 70cc => not street legal.

How to Install a cylinder on a scooter, motorcycle or moped
The cylinder or cylinder kit is the heart of the engine on scooters, motorcycles and mopeds. It consists of a cylinder, a piston with piston ring(s), a cylinder head and gaskets needed for installation.
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.
