POLINI's engineered crankcase assembly delivers advanced intake technology for Vespa PX125/150 Elestart models and Spanish Motovespa variants including PX125 Iris (99M), PX150 Iris (75M), 125 CL (9CL), and 150 CL (9NC). This performance-focused alternative to original Piaggio casings incorporates contemporary flow dynamics whilst maintaining the structural integrity characteristic of large-frame Vespa engines. Purpose-built for both street and competition applications, it provides a solid foundation for high-output engine configurations.
- 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 airbag assembly
