In a motorcycle power unit, a crank shaft (56) and a clutch shaft (57) disposed on the right side (in the figure) from a body center (127) and a cylinder head (129H) is disposed on the left side from the body center (127). Since the crank shaft, the clutch shaft and a transmission shaft are disposed on one of right and left sides with respect to the body center and the cylinder is disposed on the other side with respect to the body center, it becomes possible to make a favorable lateral balance of the power unit. |

DETAILED DESCRIPTION What is claimed is: 1.
A power unit arrangement structure for a motorcycle, said motorcycle having a body and a main frame, said power unit arrangement structure comprising a power unit including an engine, an electric motor, and a power transmission system, said power transmission system for transmitting power of said engine and for transmitting power of this electric motor and being disposable on one side of a rear wheel of the motorcycle, said engine being disposed with a crank shaft extending longitudinally of said body, said power unit arrangment structure further including means for mounting said power unit to said main frame of said motorcycle so that said crank shaft and said power transmission system are disposable on one side with respect to a longitudinal center of said motorcycle body and a cylinder head of the engine extends on the other side with respect to the longitudinal center, said power transmission shaft being disposed parallel to and higher than said crank shaft.
2.
A power unit arrangement structure for a motorcycle according to claim 1, wherein said cylinder head is a cylinder head of a four cycle engine.
3.
A power unit arrangement structure for a motorcycle according to claim 1 or 2, wherein said mounting means supports members of an intake, system and members of an exhaust system disposed on said cylinder head side.
Description:
TECHNICAL FIELD The present invention relates to a power unit arrangement structure for a motorcycle, and particularly to a power unit arrangement structure suitable for a hybrid type motorcycle including an electric motor in addition to an engine.
BACKGROUND ART Vehicles of a type using gasoline engine as a drive source are mainly available; however, vehicles of a type using an electric motor as a drive source are required at locations where occurrence of exhaust gas must be avoided.
A motor-driven vehicle, however, has an inconvenience in the increased body weight and the shortened running distance.
To cope with such an inconvenience, it has been increasingly required to develop a hybrid type vehicle including an electric motor in addition to an engine
