Description
You're looking for ultimate power for your 70cc engine? We have it - Polini 70cc Cast Iron Cylinder Kit "Corsa" MBK Ovetto / Neo's (Minarelli horizontal AC, 10mm).
The kit includes:
- 70cc Cast Iron Cylinder, with 5 transfer ports and simple oval exhaust port
- Two-Ring Piston, 10mm pin
- High-Compression Cylinder Head (long reach spark plug)
- Gasket Kit for mounting
Based on the 70cc Cast Iron Sport cylinder by the same company, this cylinder kit is designed for even more power. Polini redesigned the cylinder resulting in longer port timings and in a differently shaped exhaust duct. These modifications lead to an increase in power - it can reach appr. 10/13hp, in combination with a 17.5mm carburetor (at least) and a sports exhaust. The piston included in the Corsa kit is also special, even though it remains a two-ring piston with a 10mm pin.
The cylinder kit is NOT street-legal!
Note: you can only use long reach spark plugs with this model (such as B9ES or BR9ES).
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.
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.
