Mazzucchelli Crankshaft Vespa PX Rotary Stroke 60mm
Deskripsi Produk
The MAZZUCCHELLI long stroke crankshafts have a substantially extended intake timing, just like the racing crankshafts. The conrod is partially a polished special edged conrod, and the lower conrod bearing is a silver bearing. It is also available as a strengthened 'K2D' version. The higher solidity of the K2D alloy means it is possible to achieve a higher pressing dimension on the crank pins. This means that the torsion resistance is also increased without welding. This material is now used on all MAZZUCHELLI full circle crankshafts.
