Polini Stage2 66cc cylinder kit with ECU for Yamaha Aerox & Neos 4-Stroke 50cc Euro4 scooters (lambda sensor in the exhaust).
These kits are the second stage in tuning after fitting the Polini Lambda emulator and Hi-Speed variator kit. You will need to do this step before fitting this kit!
Polini have developed a complete cylinder kit for new fuel injected engines. The cylinder is produced using light weight aluminium alloy. Compression ratio has now been increased to 12.4:1, a larger inlet is included to increase the air flow and the ECU controls the new engine setup.
You will need to fit the Polini gear kit with this cylinder to get the most out of this kit.
