Motorcycle Engine case Assembly

This is a detailed 3D solid model of a two-piece engine crankcase, designed for a motorcycle application. The model includes all critical features such as cylinder mounting surfaces, crankshaft bearing journals, transmission housing, internal oil galleries, and external mounting points for vehicle integration. It is modeled as a solid body, making it ideal for a variety of engineering and design applications: Reverse engineering and educational studies of engine design. Serving as a digital foundation for custom engine builds or modifications. Performing Finite Element Analysis (FEA) to test structural integrity. Use within a larger, complete engine or vehicle assembly. The geometry is clean and suitable for CNC machining a prototype or creating molds for casting.
