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.\u003c\/p\u003e\u003cp\u003eNot 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.\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003eDIFFERENT VERSIONS\u003c\/p\u003e\u003cp\u003eCrankshafts are available with different piston rod lengths for \"small frame\" Vespas, on to which the full crankshaft is fitted.\u003c\/p\u003e\u003cp\u003eThe shaft for motors with a rotating valve inlet has a standard length shaft and piston rod.\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003eFULL CRANKSHAFT\u003c\/p\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003cp\u003eAs 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.\u003c\/p\u003e\u003cp\u003eThe circular mass structure is the zone which benefits the most from this new shaft and sump configuration, receiving the maximum possible pressure level.\u003c\/p\u003e\u003cp\u003eProducts reserved exclusively for racing in specifically designed locations according to the provisions of the competent sporting authorities.

Malossi engineers have in fact been able to significantly increase resistance by using a finer thread on the axle on the drive side of the crankshafts The position of the spanner has also been revised in terms of both size and shape to no longer damage the thread and to contribute to the resistance with a modern solution. The crankshafts are fitted with special nuts that are much more resistant in order to benefit from the highest resistance that the densest thread can offer.\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003eDIFFERENT VERSIONS\u003c\/p\u003e\u003cp\u003eCrankshafts are available with different lengths of connecting rod for Vespas with a ‘small frame’, on which the shaft is installed with a full collar.\u003c\/p\u003e\u003cp\u003eThe shaft for engines with a rotary valve intake has standard dimensions for the length and length of the connecting rod.\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003eSHAFT WITH FULL COLLAR\u003c\/p\u003e\u003cp\u003eThe Malossi shaft with full collar is designed solely for Vespa engines that have been modified to use an intake system with a reed valve instead of the original rotary valve. These engines represent the new limit for Vespa enthusiasts.\u003c\/p\u003e\u003cp\u003eJust like for the version with a rotary valve, the optimum balance is ensured by tungsten inserts. In addition, the back of the drive side has specially developed bevels to facilitate the intake of fresh gases into the lower housing.\u003c\/p\u003e\u003cp\u003eThe circular ground structure is the area that benefits most from this new shaft and housing configuration, as it receives the highest possible amount of pressure at all times.\u003c\/p\u003e\u003cp\u003eProducts intended solely for competition at the locations designated for this purpose and in accordance with the provisions of the relevant sports authorities.
