Description

70cc cylinder Polini Corsa Yamaha Neo's

The Corsa cylinders are another addition to Polini's racing line: Polini 70cc Cast Iron Cylinder "Corsa" Yamaha Neo's / MBK Ovetto (Minarelli horizontal AC).

Design Polini Corsa cylinder

Polini based this cylinder kit on their 70cc Cast Iron Sport kit and redesigned it to improve performance and give it more power. More specifically, Polini modified the cylinder's port timings (longer) and redesigned the shape of the exhaust port resulting in an increase of power up to 10/12hp (with a 17.5mm carburetor and a sports exhaust). The piston was also a modified as a special "Corsa" piston even though it remains a two-ring piston.

Not street-legal.

Notes and Safety

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.
