Complete Crankshaft POLINI - Manufacturer Ref: 170.0100

Complete crankshaft signed by POLINI, designed for the restoration of the bottom end of 50 cc mopeds. As a central piece of the system, the crankshaft converts the piston’s reciprocating motion into rotation via the crank pin and counterweights, thus delivering torque and cadence to the transmission hub. Supplied as a complete unit, it allows for simple replacement of the rotating assembly when play, vibrations, or a breakage render the original crankshaft inoperable.
