Design and installation Piaggio CIAO engine

The crankcase is made of die-cast aluminum and is designed to accommodate cylinders with 3 or 4 bolts. It also has a revised intake that allows the installation of carburetors with a diameter of up to 21 mm. This provides greater airflow, which improves engine performance.

Removal of the pedals is required for installation. On the Piaggio Ciao, a slight cut-out must be made in the frame (see installation instructions).

Notes and Safety

Polini For Race

The For Race series from Polini includes exhausts as well as crankshafts and clutches for scooters, 50cc supermotos and Vespas. Although the name sounds like ultra-high-quality and high-performance racing parts, this is not quite true.

The exhausts are not road-legal and are theoretically only intended for use on the race track, but due to their performance, which focuses mainly in the lower and medium RPM range, they are more suitable for sports / entry level tuning setups, which are appreciated for their balanced ratio of performance and reliability for everyday use.
The crankshafts are also suitable for sports cylinders, as are the few For Race clutches.

Polini fans looking for maximum power for the racetrack should therefore opt for the Evolution or even the P.R.E. series.
