Mazzucchelli racing shaft for Vespa PK50 XL with Ø 20 mm cone

To achieve higher engine speeds, you should use the racing shaft. The extended intake timing allows the engine to rev much more freely. This measure is particularly noticeable with high-speed cylinders.

The quality of the crankshafts is very good and they can withstand even the highest speeds. They are an ideal addition, especially for the larger displacement engines from 125 cc upwards, to extend the usable speed range of racing cylinders without spitback in the lower speed range.

These engines offer both a decent torque over the entire speed range and free revving without the engine running out of air on inclines.

The PK XL shaft also offers the enormous advantage that it has a very stable cone and can therefore withstand much higher forces. In addition, it enables the use of ultra-light pole wheels, with which better acceleration behavior can be achieved.

TIP: For cylinders from 75cc displacement, order a wider upper connecting rod bearing directly! (see accessories)

Super Rennwelle, gute Verarbeitung, meiner Meinung nach war bei den älteren Wellen das Pleuelspiel zu groß bei dieser nicht mehr. Schöne Verlängerung der Einlasszeit.
