Full crankshaft long-stroke crankshaft with 60mm stroke for PX 125. Mazzucchelli full crankshafts are known for their robustness and, due to their design, provide high pre-compression. The high pre-compression promotes the intake of fresh mixture.
The Mazzucchelli full crankshaft offers a cost-effective option for Vespa PX membrane engines.
Ideal for direct intake. For intake through the engine housing, the lip shaft or the bell shaft are better choices because the cheeks of the full crankshaft otherwise obstruct the mixture during intake.
Mazzucchelli code: AMT162MVT
