Abstract

An internal combustion engine (300) for a vehicle, such as a motorcycle (20), includes a crankcase (380), two banks of cylinders (320a, 320b) projecting from the crankcase (380) in a V-configuration, a plurality of pushrods (364), and a plurality of camshafts (360a, 360b, 360c) supported by the crankcase (380). The two banks of cylinders (320a, 320b) include a first cylinder bank that projects from the crankcase (380) to a first cylinder head (340a), and a second cylinder bank that projects from the crankcase (380) to a second cylinder head (340b). The plurality of pushrods (364) extend between the crankcase (380) and the first and second cylinder heads (340a, 340b), and the plurality of camshafts include only the first, second and third camshafts (360a, 360b, 360c).
