NUOVA MAZZUCCHELLI – Crankshafts born of tradition

Not all Vespa enthusiasts realise that crankshafts are wear parts – at least when riding a two-stroke. A new crankshaft should be fitted after around 20,000 km. And that’s where NUOVA MAZZUCCHELLI comes in, as the Italians deliver the quality you’d expect from genuine Piaggio parts. Even those with a tight wallet can afford a crankshaft from this manufacturer and will be making the right choice. In the manufacture of its mechanical parts, NUOVA MAZZUCCHELLI combines state-of-the-art production techniques with skilled craftsmanship. This is the only way to put the company’s philosophy into practice, which is: continuous research and ever-improving design solutions.
But even beginners can get into tuning with parts from NUOVA MAZZUCCHELLI: Racing Crankshafts are a simple and effective tuning upgrade for any rotary engine. A Racing Crankshaft enables higher revs. The engine becomes livelier and more agile. The high-quality Racing Crankshafts from the Italian company NUOVA MAZZUCCHELLI impress with minimal manufacturing tolerances and low bearing play. This guarantees high rotational stability and maximum durability. Unlike the original Crankshaft, a Racing Crankshaft has a significantly extended intake stroke. This increases the filling ratio. The crankshaft journals are aerodynamically optimised and polished. Turbulence and flow separation are reduced. A similarly polished blade-type connecting rod and a lower connecting rod bearing made of silver meet the highest standards. All crankshafts are supplied with upper connecting rod bearings.
Naturally, a tuned cylinder is the ideal choice in combination with a Racing Crankshaft, but a performance boost can also be achieved with a standard cylinder. NUOVA MAZZUCCHELLI’s crankshafts and Racing Crankshafts are synonymous with long service life and durability. The Italian manufacturer’s range also includes Long Stroke Crankshafts, Full Circle Crankshafts and Bell-Shaped Crankshafts.
