POLINI ENGINE CRANKCASE VESPA PX 125-150 170.0601

Polini crankcase for Vespa PX / PE – Performance and reliability without compromise

The new Polini crankcases for the Vespa PX 125/150 and PX 200 E represent a true technical evolution for those who want to build a high-performance engine while maintaining compatibility with the original components. Completely redesigned and manufactured with high-precision machining, they are designed to offer greater structural strength, optimized fluid dynamics, and superior reliability even in the most demanding tuning applications.

Main features:

• Flat reed valve intake
• Compatible with 28/30mm racing carburetors
• Reinforced casings in the areas subject to greater stress
• Oversized ignition side bearing (25x52x15)
• Ground steel flanges on the clutch side
• Fixing with M8 screws for greater rigidity
• Provision for electric start
• Oil cap repositioned to improve lubrication
• Fork geometry optimised with FEM analysis
• Transfers and internal volumes developed through CFD simulations

Made of Al Si10 Mg T6 aluminium alloy , shell-cast and heat-treated, they guarantee high mechanical resistance, excellent heat dissipation and maximum reliability over time.

The absence of the classic central gasket improves the coupling precision between the crankcase halves, increasing the seal and structural stability of the entire engine unit.

The ideal solution for those who want to build a high-performance, reliable Vespa, ready for both advanced road use and racing configurations.
