STRENGTH AND RESISTANCE
MALOSSI CRANKSHAFTS FOR VESPA
The crankshaft of a Vespa is one of the most delicate yet important components of this type of propulsion unit, having to handle the movement of rods and pistons, as well as regulating intake through the crank timings.
The Malossi technical office has dedicated its attention to both of these elements, creating two versions of the crankshaft and developing unique solutions with a high technological value, starting with the choice of materials; top quality as always.
All Malossi crankshafts for Vespa are made from aeronautical quality reinforced steel and are founded in a vacuum. It is a material highly resistant to scratches and guaranteed by the certifications required in Malossi's strict handbook. The "viper head" piston rod's shape is designed to limit weight to a minimum whilst guaranteeing the required rigidity.
Not even the smallest detail has been overlooked. Indeed, Malossi technicians have even worked on the thread on the transmission side axis of the crankshaft, succeeding in significantly increasing resistance by producing smoother stepping. Even the position of the key has been reviewed both in terms of size and shape, so as to no longer damage the thread and contribute to resistance in what is an avant-garde solution. Crankshafts are supplied with special nuts, much stronger, to take advantage of the increased resistance offered by the tighter thread.
DIFFERENT VERSIONS
Crankshafts are available with different piston rod lengths for "small frame" Vespas, on to which the full crankshaft is fitted.
The shaft for motors with a rotating valve inlet has a standard length shaft and piston rod.
FULL CRANKSHAFT
The Malossi full crankshaft, designed only for Vespa motors modified for use with a reed valve inlet systems instead of the original rotating valve, is the next level for Vespa enthusiasts.
As with the rotating valve version, this version is also guaranteed to offer optimal balance, having tungsten inserts. Furthermore the half crank on the transmission end has a specially-designed chamfer to ease fresh gas intake under the sump.
The circular mass structure is the zone which benefits the most from this new shaft and sump configuration, receiving the maximum possible pressure level.
Products reserved exclusively for racing in specifically designed locations according to the provisions of the competent sporting authorities. We disclaim all liability for improper use

Malossi needle roller bearings are independent bearings that are ready for assembly and constructed from high-tensile steel with housings for the insertion and axial rotation of the rollers. These devices are designed to allow reciprocal movement between two objects, constraining the rotation of the cage and housing the rotating elements with reduced overall dimensions, negligible weight and reduced friction. These are essential components in internal combustion engines which, by definition, have several rotating elements. As can be seen in the image, a needle roller bearing assembly is made…

Special bearing machined internally to be lowered to 14 mm. It fits oversize balls to withstand an increased load with reduced internal friction. The thermochemical treatment of the rings guarantees maximum hardness and wear resistance. Thanks to the increased internal clearance this bearing can withstand very high RPMs without overheating.

DISTINGUISHING FEATURES OF THE CRANKSHAFT FOR 100 CC CYLINDER The Malossi crankshaft for the 100 cc cylinder is primarily composed of two half-shafts forged from special steel, machined on high-precision CNC tools, and then subjected to a thermochemical treatment involving carburizing, hardening, and cryogenic cooling in nitrogen . This process gives the halfshafts exceptional hardness and strength , essential for supporting the high power output generated by the 100 cc cylinder. The surfaces of the crankshaft are then ground with high-precision equipment, particularly the bearing seats,…
