Racing crankshafts are a simple and effective tuning step for every disc valve engine. A racing crankshaft enables higher numbers of revs. The engine becomes more lively and agile. The high quality racing crankshafts from Italian company MAZZUCCHELLI convince thanks to their minimum production tolerances and limited bearing clearance. This guarantees high rev endurance and an exceptionally high product lifespan.

MAZZUCHELLI has been delivering premium quality Vespa crankshafts with excellent value-for-money, for decades. They are 100% identical to the originals in appearance, production quality and port timings.
