Details

Polini is one of the big names in 50cc scooter tuning, and is also one of the leading manufacturers of tuning parts for Vespa, modern and vintage. Cylinders, intake manifolds, exhausts, air filters, carburetors, crankshafts and more - everything you need to boost the performance of your classic Vespa.

Crankshaft Polini Evolution, Vespa ET3 / Primavera 125/ PK125, 52.8mm stroke, long stroke tuning crankshaft with reinforced connecting rod and extremely hard-wearing small end + big end bearings.

A longer stroke translates into more power, which is what you want in a powerful, large displacement engine. In combinaton with a 57mm bore cylinder (such as the Polini Evolution this crankshaft was originally designed for) displacement is almost 135cc – not bad at all!

This HQ crankshaft features excellent manufacturing quality and premium quality materials. The counterweights are made of a heavy metal alloy and provide optimum balancing.

  • reinforced crankshaft
  • steel connecting rod
  • 20mm journals
  • stroke = 52,8mm
  • 102mm connecting rod
