crankshaft Polini Big Evolution 44mm stroke for Minarelli AM6

To get unspeakable 94cc, you need not only a cylinder with a large bore. You also need a longer stroke.

This Polini Big Evolution crankshaft is specially matched to the Polini Big Evolution cylinder kit. With 44mm stroke and an incredibly high manufacturing quality, it is the perfect companion for the currently strongest series cylinder that the tuning world for AM6 engines currently has to offer.

This Polini crankshaft can of course also be driven with another cylinder, insofar as this requires a 44mm stroke shaft.
