The Polini Sport 50ccm cylinder kit is of the same high quality and with good durability as its big brother - but of course with somewhat lower power. Just like its big brother, this cylinder kit is with one large exhaust port and therefore has a good bottom feature. The cylinder is made of cast iron and we therefore recommend a driveway of about 200km. For this cylinder, use a spark plug with a long thread - we recommend that NGK BR8ES . The kit is delivered complete incl. gaskets, piston rings, etc.
NOTE: This cylinder has been modified, hence the nickname (MOD), which means that it fits in a limited block, but does not fit with Euro2 exhaust. The kit is with ø10mm cross stick.
