POLINI Crankshaft (manufacturer reference: 210.0054): a crankshaft designed for urban mopeds where reliability and performance at high revs are essential. The connecting rod is machined as a single piece to enhance resistance to stress and improve durability. The intake adjustment has been revised to optimize engine behavior, while the crankshaft design has been refined to minimize vibrations felt at the handlebars. The result: a robust part, designed for daily riding and compatible with both original and modified engines.
Ideal for urban riders looking for a reliable replacement or upgrade for their 50 cc engine. Check compatibility with your model before ordering: for example, PIAGGIO APE 50 (2017), VESPA PK HP (1999), and VESPA PK XL (1991) are among the common applications.
