Mazzucchelli Racing crankshaft 57 mm for Vespa PX200
To achieve higher engine speeds, you should use a racing crankshaft. 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 engines with a larger displacement, in order to extend the usable speed range. These engines rev freely, which leads to a significant increase in top speed.
