Abstract

A motorcycle includes a body frame, and an internal combustion engine having a crankshaft, a drive shaft, an upper crankcase disposed above the crankshaft and the drive shaft, a lower crankcase (60) disposed below the crankshaft and the drive shaft, and a cylinder body disposed above the upper crankcase and having a plurality of cylinders arranged transversely. The lower crankcase (60) has a left boss portion (130) and a right boss portion (134) respectively having holes (132), (136) for receiving a rod-shaped fastener extending transversely, and secured to the body frame by the fastener. The lower crankcase (60) includes an oil passage (160) through which oil to be supplied to the drive shaft flows, the oil passage (160) formed integrally with the lower crankcase (60).
