Restore the primary heart of your engine with this premium Replacement Crankshaft Assembly for Vintage Vespa P/PX Series scooters.

- High-Strength Connecting Rod: Equipped with robust top and bottom wrist pin bearings engineered to handle continuous high-RPM urban riding.
- Factory Balanced: Minimizes rotational harmonic vibration, protecting your stator assembly and clutch basket.
- Direct Vintage Fitment: Keyways and taper profiles are cut to exact vintage dimensions for seamless flywheel and clutch integration.
