Preview: Crankshaft -MAZZUCCHELLI RACING (reed valve intake) full circle web- Vespa PV125, ET3 125, PK80 S, PK125 S (Ø=19mm cone)

Description

The solid cheek shaft is particularly suitable when a cylinder with direct intake is driven. Here, increasing the pre-compression with the correct exhaust selection leads to a significantly better filling of the cylinder over the entire speed range.

Milling artists can also drive the shaft on the housing inlet.
