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.
