Zusammenfassung:	A motorcycle crankcase is configured to support a crankshaft in a manner such that the crankshaft is rotatable about a crankshaft axis. The motorcycle crankcase comprises a pair of piston cylinder mounts, first and second horizontally oriented downward facing mounting surfaces, a generally semi-cylindrical bottom surface, and a plurality of crankcase bolt lugs. The pair of piston cylinder mounts are configured and adapted to rigidly connect to a pair of piston cylinders oriented in an upright V-twin style manner. The first and second mounting surfaces are configured and adapted to secure the motorcycle crankcase to a motorcycle frame. The crankcase bolt lugs are spaced about the crankshaft axis and each of the crankcase bolt lugs partially protrudes radially outward from the bottom surface. The motorcycle crankcase is devoid of any portion positioned directly beneath the first mounting surface.
