Descripción FUERZA Y RESISTENCIA CIGÜEÑALES MALOSSI PARA VESPA El cigüeñal de una Vespa es uno de los componentes más delicados, pero igualmente importantes, de este tipo de unidad de propulsión, ya que debe manejar el movimiento de bielas y pistones, así como regular la admisión a través de los tiempos del cigüeñal. El equipo técnico de Malossi ha dedicado su atención a ambos elementos, creando dos versiones del cigüeñal y desarrollando soluciones únicas de alto valor tecnológico, comenzando por la selección de materiales; de primera calidad como siempre. Todos los cigüeñales Malossi para Vespa están hechos de acero reforzado de calidad aeronáutica y fundidos al vacío. Es un material altamente resistente a los arañazos y garantizado por las certificaciones requeridas en el estricto manual de Malossi. La forma de la biela "cabeza de víbora" está diseñada para limitar el peso al mínimo garantizando la rigidez necesaria. No se ha pasado por alto ni el más pequeño detalle. De hecho, los técnicos de Malossi incluso han trabajado en la rosca del eje de transmisión del cigüeñal, logrando aumentar significativamente la resistencia al producir un roscado más suave. Incluso la posición de la chaveta ha sido revisada tanto en tamaño como en forma, para no dañar más la rosca y contribuir a la resistencia en lo que es una solución de vanguardia. Los cigüeñales se suministran con tuercas especiales, mucho más fuertes, para aprovechar la mayor resistencia ofrecida por el roscado más ajustado. VERSIONES DIFERENTES Los cigüeñales están disponibles con diferentes longitudes de bielas para las Vespas de "cuadro pequeño", a las cuales se les ajusta el cigüeñal completo. El eje para motores con admisión de válvula rotativa tiene un eje y biela de longitud estándar. CIGÜEÑAL COMPLETO El cigüeñal completo de Malossi, diseñado solo para motores Vespa modificados para usar sistemas de admisión de válvula de láminas en lugar de la válvula rotativa original, es el siguiente nivel para los entusiastas de Vespa. Al igual que con la versión de válvula rotativa, esta versión también garantiza un equilibrio óptimo, teniendo insertos de tungsteno. Además, la media luna del cigüeñal en el extremo de transmisión tiene un bisel especialmente diseñado para facilitar la admisión de gas fresco bajo el cárter. La estructura de masa circular es la zona que más se beneficia de esta nueva configuración de eje y cárter, recibiendo el nivel de presión máximo posible.

STRENGTH AND RESISTANCE
MALOSSI CRANKSHAFTS FOR VESPA
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.

STRENGTH AND DURABILITY
MALOSSI CRANKSHAFTS FOR VESPA
</p
The Vespa crankshaft is one of the most delicate and fundamental components of this type of power unit, as it has to control both the movements of the connecting rod and the piston, as well as regulate the intake using the timing mechanism.
The Malossi technical department has paid particular attention to these two aspects, creating two versions of crankshafts and developing new solutions of high technical value, starting with the selection of the materials, which, as always, are of the highest quality.</p
All Malossi crankshafts for Vespa are made of hardened, vacuum-melted steel of aeronautical quality, a material that is highly resistant to scratches and is guaranteed by the certifications required by strict Malossi specifications The connecting rod with a ‘viper head’ has a sophisticated design to absorb maximum weight and guarantee the required strength.</p
Not even the smallest detail has been overlooked. 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.
DIFFERENT VERSIONS
Crankshafts are available with different lengths of connecting rod for Vespas with a ‘small frame’, on which the shaft is installed with a full collar.
The shaft for engines with a rotary valve intake has standard dimensions for the length and length of the connecting rod.
SHAFT WITH FULL COLLAR
The 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.
Just 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.</p
The 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.</p
Products intended solely for competition at the locations designated for this purpose and in accordance with the provisions of the relevant sports authorities. We do not accept any liability for improper use.
