Where is the air intake of a motorcycle located?

Motorcycle's air intake is located at the upper front part of the engine, specifically at the intake pipe position between the carburetor and the engine. A motorcycle is a two-wheeled or three-wheeled vehicle driven by a gasoline engine, steered by handlebars to control the front wheel. It is lightweight, flexible, and fast, widely used for patrol, passenger and cargo transportation, and also serves as sports equipment. Broadly speaking, motorcycles are divided into street bikes, road racing motorcycles, off-road motorcycles, cruisers, and touring bikes. A motorcycle consists of five main parts: the engine, transmission system, running gear, braking system, and electrical instrumentation equipment. The transmission system of a motorcycle includes primary reduction, clutch, gearbox, and secondary reduction.
The position of a motorcycle's air intake is generally near the engine or at the front/side of the vehicle body, depending on the model's design and construction. Having ridden various types of motorcycles, I've noticed that on street bikes, the intake is often located above the engine or behind the radiator shroud for direct air intake. On cruisers or off-road bikes, it may be concealed under the seat or near the fuel tank area to avoid mud clogging during off-roading. To locate the air intake, I carefully inspect the front or engine cover, where there is usually an opening or an air filter box connected. While riding, I pay attention to the sound of the air inlet. The position is crucial because it affects engine efficiency and performance—excessive wind resistance or improper placement can hinder acceleration, especially on highways where wind direction matters. For routine maintenance, regular inspection of the air intake's cleanliness is essential. I recommend gently brushing off accumulated dust every 300 kilometers using a soft brush to prevent leaves or debris from blocking airflow. If riding conditions change, such as in sandy or dusty areas, installing a protective mesh is a good idea to prevent premature wear on engine components.
