Polini Sport cylinder 70cc for Piaggio 2-stroke AC

The POLINI 70cc SPORT is a perfect all-round cylinder.
Very durable and finely crafted cast iron cylinder, which gets its power mainly from the increased displacement.

Good workmanship, large channel surfaces and very good quality characterize this cylinder. Grows with the tasks and the expansion stages carried out.

Either you fit it with the original carburetor and have fun straight away or you continue tuning and have fun until the doctor comes. This kit is therefore a great basis for powerful engines. From touring to street racing, everything is possible here.

If it is to be ridden without further modifications, the main jet must be adjusted (5-10 % larger).

Larger carburettors with a diameter of 17.5 mm to 19 mm and correspondingly designed exhaust systems are recommended as initial measures for further performance enhancements.

Delivery includes pistons, gaskets and the necessary assembly material.
This is how we ensure, that reviews come from real consumers.

So far so good

Der Klassiker schlecht hin. Absolut passgenau. Drehmoment und Drehzahl sind für dieses Segment ideal aufeinander abgestimmt.
