The Polini Sport 70ccm cylinder kit improves your scooter's performance and this can especially be felt on the pull-up. The cylinder is made of cast iron, which provides good durability and helps make it a reasonable upgrade compared to the original cylinder. The piston and cylinder head are made of aluminium, so the heat is dissipated quickly. For cast iron cylinders, we always recommend an approach 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. NOTE: This cylinder fits directly into the engine block on models from year 2003-> without the restriction in the engine is removed. This is NOT relevant for PGO engines.
NOTE: This cylinder fits in limited block, but does not fit with Euro2 exhaust.
