Polini Vespa Crankcase Rotary Valve, Reed Valve (Electric Start Compatible) PX200
POLINI's reimagined crankcase assembly for Vespa PX125/150 and PX200 integrates advanced intake flow dynamics with the time-tested reliability of traditional large-displacement engines. Built around vane-controlled induction principles, this precision-engineered component maintains full compatibility with factory Vespa parts whilst establishing a robust platform for demanding street performance and track applications. Electric start capability is preserved throughout.
- Facilitates reed valve intake conversion with compatibility for 28/30mm carburettor options, modernising your PX engine's fuel delivery system.
- Can be used as a replacement for the original Piaggio or Motovespa engine housing
- CFD optimized gas flow in crankcase and transfer ports for higher performance
- FEM-reinforced swing arm and transmission housing designed to support wider rear tyres with enhanced structural integrity.
- Larger crankshaft bearing, steel flange and modified sealing solution on the clutch side
- Made of high-quality Al Si10 Mg T6 alloy, heat-treated for maximum stability
This can be used with the standard Vespa PX airbox assembly
