Polini Corsa
With the Corsa cylinder series from Polini, the name says it all, because Corsa means racing. The Corsa is a cast iron racing cylinder for 50cc scooters, known for its excellent ratio of reliability and performance. The Corsa has been around for a very long time and still has many friends and fans.
Advantages of the Polini Corsa
- Cast iron cylinder - easy installation, no squish adjustment
- Durable 2-ring piston for everyday use
- High performance
- Carbon reed petals included
- HC cylinder head
To make full use of the Corsa's performance, it should be combined with a racing exhaust and a well-adjusted carburetor with a large diameter. Readjusting the CVT is also recommended.
When to replace the piston?
To find out when the piston on your motorcycle, scooter or moped needs to be replaced, it's best to check your bike's manual. You can also keep an eye out for certain symptoms such as loss of compression, loss of power or oil consumption (only for a four-stroke piston).
Extending Piston life
To extend the life of the piston and reduce cylinder wear, it is recommended that you replace the piston rings on an alternating basis. This method maximizes piston life and improves engine performance.
It is important that you replace cylinder gaskets and piston circlips each time you disassemble the cylinder and piston. Failure to do so can result in oil leaks and engine damage.
Tuning Level: Racing
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.
Racing products are designed for a more extreme uses and are developed primarily for racing. Whether you stay at 50cc or increase the displacement, the corresponding Racing parts produce much higher performance than the original parts in order to achieve maximum power.
