Information on product safety

Mazzucchelli repro crankshaft for Vespa PX125/PX150

High-quality repro of the Vespa PX crankshaft by Mazzucchelli.

The shafts from the renowned Italian company Mazzucchelli are a very high-quality replacement for the standard crankshaft.

The high-quality workmanship and very good bearings prevent the shaft from bearing collapse even at maximum speeds. As the heart of the engine, the shaft plays a major role in determining reliability, and any sloppiness here can be costly.

This is how we ensure, that reviews come from real consumers.
