Vespa Engine and Parts
Engine and parts: The heart and driving force of the Vespa, the Engine and parts section is located at the rear of the vehicle, firmly anchored to the frame by two pins:
the first, at the end of the central tunnel and the second to the shock absorber.
Given its importance, the engine is composed of numerous and different parts. In a complete overhaul, it is good to check the wear of all the spare parts, paying particular attention to the crosspiece,
