The first motorcycles were little more than bicycles with crude motors attached to power them.
Modern motorcycles can include high tech components that make them very different from those earlier models. A motorcycle can be described as a combination of systems, each of which needs specific parts to function properly.
A motorcycle is powered by its drivetrain. This includes the engine, which is almost always an internal combustion engine that uses conventional gasoline as fuel.
Motorcycle engines are usually centrally mounted below the driver’s seat. A carburetor blends fuel with air before it is drawn into the ending for combustion, though some high end models now use fuel injectors in place of carburetors.
A motorcycle’s engine conveys power to the rear drive wheel through its transmission. The transmission itself is attached to the engine, and operated by a shift lever (usually a lever attached to one of the handlebars) and a clutch (usually a pedal operated by the left foot).
The system connecting the transmission to the rear wheel (the final drive) varies on different types of motorcycles, and may be a chain or belt, or a solid shaft. Continue reading Parts of a Motorcycle
