CRANKSHAFT POLINI EVOLUTION VESPA 125 ET3 FULL CIRCLE D.20 S.54 CONROD 105
Users feedback
Description
The shape of the circular bodies drastically reduces the casings internal turbulences increasing compression of the gases that go into the head during the burning phase. The balance has been achieved using inserts made of tungsten and aluminium caps to reduce the volumes.
It is compulsory to bore the case before fitting it.
The Polini "Evolution full-circle crankshaft" increases the stroke up to 54 mm.
The connecting rod is machined from a block, with 105 mm inter-axis.
The assembly of this product allows to reach a displacement of 152cc.
All the Polini crankshafts are perfectly balanced and grant the best performance.
