The crankcases, produced through a vacuum casting technology called Vacural®, ensure a maximum reduction in weight, a uniform wall thickness and superior mechanical strength, and are designed in such a way to incorporate the water jacket around the cylinder barrels. The Superquadro engine is fitted with aluminum wet barrels coated in Nicasil inserted into the holes of the engine block's housing during the initial stages of assembly. This design allows the head to be fastened directly onto the crankcase, combining the needs for rigidity of the engine's structure with a significant advantage in terms of compactness. Due to their thin walls, the barrels also achieve an effective thermal exchange with the coolant running along the walls. In addition to the barrels, the crankcase stands out for the use of main bearing shells, previously utilised only in the Ducati Desmosedici RR engine. The elimination of the ball bearings has made it possible to increase the diameter of the journals for the main bearings of the crankshaft, allowing an increase in the section of the engine block in the area surrounding the main bearing journals so as to maximise the rigidity and the mechanical strength and adapt it to the extreme power of the Superquadro.
