Polini Corsa 75cc cast-Iron cylinder kit  for Vespa PK & Smallframe 50cc engines.

High-quality cast-iron cylinder designed for Piaggio APE 50 (including FL, FL2, FL3, RST MIX 6-spring) and Vespa 50 2T models (PK, SPECIAL, XL). 

A newly designed chilled head featuring a modern, reinforced structure with optimised squish and a centrally positioned long-thread spark plug improve combustion efficiency. The enhanced cooling fins ensure superior heat dissipation, while the steel head gasket with silicon content guarantees a perfect compression seal between the head and cylinder, an advantage not found on the original Vespa.

This kit offers high build quality and performance, it features an exhaust port with booster holes for improved gas flow and performance.

Material: Cast iron

Bore: 47mm

Note: Use a spark plug with long thread.
