The Polini Sport 70ccm cylinder kit improves the performance of your scooter and this can be especially felt on the towing. The cylinder is made of cast iron, which gives good durability and helps to make it a sensible upgrade compared to the original cylinder. Piston and cylinder head are made of aluminum, so the heat is quickly dissipated. For cast iron cylinders, we always recommend a run-in of min. 200km. For this cylinder kit we recommend using an NGK BR8ES spark plug and the kit is delivered complete incl. gaskets, piston rings, etc.
