The POLINI 70ccm SPORT is a perfect all-round cylinder.
Very durable and finely finished cast iron cylinder, which gets its performance mainly from the increase in displacement.

Good workmanship, large channel areas and a very good quality distinguish this cylinder. Grows with the tasks and the performed expansion stages.

Either you build it with the original carburetor on it and have fun immediately or you continue to tune and have fun until the doctor comes. This kit is thus a super basis for potent engines. From Touring to Streetracing everything is possible here.

If it is to be driven without additional modifications, the main jet must be adapted (5-10% larger).

As first measures for further performance increases larger carburettors with a diameter of 17.5mm to 19mm and accordingly designed exhaust systems are recommended.

Delivery includes pistons, gaskets and necessary assembly material.
