ABSTRACT:
A motorcycle has a V type engine with its cylinders inclined other than vertically or horizontally, with a crankshaft extending transversely on the cylinders lying in a forwardly-directed vertical plane. A transmission is mounted to the motorcycle rearwardly of the engine, and has a main shaft adjacent to the crankshaft with its axis rearwardly of and at an elevation beneath the axis of the crankshaft. Stud bolts screw into the crankcase, the arrangement of the shafts enabling the wall thickness of the crankcase to be locally increased to provide for sufficient strength of threads without creating interference with the gears on the main shaft.
