Malossi crankshaft with diam 16mm and stroke 60mm for Vespa PX200E/Cosa 200 2T

CRANKSHAFT WITH PIN Ø 16, CONNECTOR 110, 60 MM STROKE AND LAMELLAR VALVE

The crankshaft of the Vespa is one of the most delicate and important components of this type of engine, having to manage both the movements of the connecting rod and piston, which regulate the admission through the phasing of the half-coat.

The Malossi technical office has focused its attention precisely on these two aspects, creating two versions of crankshaft and developing new solutions of great technical value, starting from the choice of materials, as always of first quality.

All Malossi crankshafts for Vespas are made of aeronautical quality cemented steel and remelted in vacuum, a material highly resistant to scratches, guaranteed by the certifications required by the very strict Malossi specifications. The "viper head" connecting rod has a conformation designed to keep weight to a minimum and guarantee all the necessary rigidity.

Not even the smallest detail has been overlooked. The Malossi technicians, in fact, even intervening on the thread of the transmission-side axle of the crankshafts, have succeeded in considerably increasing the resistance by using a finer wheelbase. Even the position of the key has been revised both in size and shape, so as not to affect the threading anymore and contribute to the resistance in a finally cutting-edge solution. The crankshafts are supplied with special nuts, much more resistant, to take advantage of the greater resistance offered by the thicker thread.
