The Malossi crankshaft is a fundamental component. This crankshaft is made with high-quality materials, such as aeronautical grade hardened steel, which makes it highly resistant to scratches.
The connecting rod, called the viper head, is designed to minimize weight and ensure necessary rigidity. The threading on the transmission side has also been improved, increasing strength with a finer pitch. The position of the keyway has been revised to avoid damaging the threading and contribute to resistance. The crankshafts are supplied with special, more resistant nuts.
Various connecting rod lengths are available for small frame Vespa models that require a full shoulder crankshaft. For engines with rotary valve intake, the crankshaft has standard measurements for stroke and connecting rod length. The intake phase has been carved inside the semi-shoulder, creating a unique shape that ensures effective fluid dynamics.
To solve the balancing problem, Malossi has included tungsten inserts as counterweights to increase the stability of the crankshaft.
