Robust 70cc Naraku sport cylinder kit (cast iron) for scooters with water-cooled Piaggio engines built from 1997 and up (pentagonal type). The Naraku piston is provided with a molybdenum coating, which protects the cylinder and piston during the run-in period. This coating dissolves completely after a few hours of operation.

The cylinder is suitable for series and sports exhaust systems. If the original carburettor remains installed, the carburettor jetting should be increased by about 7-10% (guide value). It is recommended to use a 17.5-19mm sports carburettor. Delivery includes gasket set, the original cylinder head can be used, but a 70cc cylinder head is recommended (sold separately).
