Crankshaft Polini Piaggio Ape / Vespa 50

Product description

With the aim of improving the quality and performance of original components, Polini has started the production of the new FOR RACE crankshafts for the well-known Vespa 50 Special, PK and Ape 50.

As used in racing engines, the connecting rod is machined from a single solid block, increasing resistance to mechanical stress. The intake has been revised to improve engine performance, and the crankshaft design has been optimized to reduce vibrations.

Safe and reliable, this crankshaft is recommended for both original and modified engines.

The crankshaft is manufactured in Italy, using only the highest-quality materials.
