Metrakit Hyper Pro Derbi Engine Crankcase (700C0100) represents the ultimate evolution for Derbi Euro 3 / Euro 4 engines intended for racing and Hyper Racing configurations. Designed for direct installation of FL-type cylinders without modifications, it is the ideal component for extreme builds.
Made from high-strength cast aluminum, this crankcase was developed to exceed the limits of the original Derbi crankcases, which were not designed for high power outputs. Its reinforced structure, combined with a design optimized for flow and cooling, makes it essential for engines producing over 30–40 HP.
