Malossi crankshaft for Vespa P ETS 125 with diaphragm valve

This Malossi crankshaft is designed for the Vespa P ETS 125 from the 1983-1990 model year range. It combines the precise guidance of the connecting rod and piston with a design for the inlet via a diaphragm valve.

• Crankshaft with pin ø 15
• Connecting rod 97 mm
• Stroke 51mm
