The “Advanced” Polini crankshafts have been properly developed to be
installed on the mythic Vespa PE200. They are recommended for all the applications, but they exploit their maximum performance together with the upgrade Polini cylinder kit.
As for the race engines, the connecting rod is machined from a block to increase its resistance to stresses. The setting of the intake has been modified to improve the engine performance and the design of the crankshaft has been optimized to reduce vibrations. Safe and reliable, their assembly is recommended both on original and tuned engines.
