Crankshaft -POLINI Racing (rotary valve)- Vespa PV125, ET3 125, PK80 S, PK125 S (Ø=20mm cone)
Part no.:
P2100033
Description
Extremely high quality processed rotary vane racing shaft. The processing leaves nothing to be desired. The immense development work of the Polini engineers is not least reflected in the elaborate balancing of the shaft. Tungsten opposite the crankpin and balancing holes filled with resin next to the crankpin ensure low vibration engine running and corresponding performance advantages.
Sufficiently dimensioned lubrication slots and racing bearings ensure high reliability. The connecting rod is heavy and solid and CNC finished.
The longer control times of the rotary vane shaft ensure a higher filling level and more power.
