Mazzucchelli Racing crankshaft with 57 mm stroke for Vespa Largeframe

Crankshaft -MAZZUCCHELLI RACING 57 mm stroke for Vespa Sprint, GL150

High quality Mazzucchelli reproduction of the original Vespa crankshaft stroke. The shaft differs from the original shaft in the extended intake time. This has the advantage of increasing the filling level of the crankcase and thus also of the cylinder at higher engine speeds. Result: More power and top speed. Fits all Vespa 125-150 Largeframe models built between 1958 and 1976.

This is how we ensure, that reviews come from real consumers.
