ABSTRACT:
A motorcycle is provided with a compact, lightweight power unit that allows for increased maneuverability and increased bank angles while turning. The power unit includes an engine and transmission integrated into a single unit. Often, the balance and maneuverability of a motorcycle are influenced by the heaviest components of the vehicle, such as the engine or power unit. The present advantage is accomplished by providing the power unit with a water pump, oil pump and transmission which are balanced on the motorcycle, limiting the weight variations and protrusions from the motorcycle. This results in allowing the motorcycle to achieve greater bank angles for better turning speeds and maneuverability. It desirable to keep the vehicle center of gravity as low as possible in a motorcycle which is likely to lean steeply around corners. The present arrangement provides the vehicle with a lower center of gravity thereby increasing maneuverability.
