Description
Reproduction of the Vespa PX crankshaft, cleanly and qualitatively executed by Mazzucchelli.
The shafts of the renowned Italian company Mazzucchelli are a very high-quality replacement for the standard crankshaft.
The high-quality processing and the very good bearings protect the shaft from bearing collapse even at maximum speeds. The shaft, as the heart of the engine, is the decisive factor for the reliability of the crankshaft.
