What is the plastic on a motorcycle called?

1, Naming and classification of plastic components for motorcycles
There are various types of plastic components on motorcycles, which can be divided into the following categories based on their position and function on the motorcycle:
Shell and Cover: These are the most prominent plastic components on motorcycles, covering the body and most of the internal structure of the motorcycle. The naming of these components is usually related to their location, such as the hood, seat cushion cover, side guard, etc. These shells and covers not only provide the overall appearance of the motorcycle, but also serve to protect the internal structure, reduce wind resistance and noise.
Handle and foot pedal: The handle and foot pedal are the parts that the rider comes into direct contact with the motorcycle, and they are usually made of plastic materials to provide a comfortable feel and anti slip performance. A handle usually includes gloves, a handle switch, etc., while a foot pedal includes a foot pedal, a foot lever, etc. The naming of these components is intuitive and easy to understand, directly describing their functions and usage locations.
Fuel tank and air filter: Although fuel tanks and air filters are mainly made of metal or other materials, some of their components or casings may be made of plastic materials. The naming of these plastic components is usually related to their function, such as fuel tank covers, air filter housings, etc. Their main function is to seal and protect internal components, while providing easy to open and maintain interfaces.
Lighting and Signal Equipment: Lighting and signal equipment on motorcycles, such as headlights, turn signals, brake lights, etc., typically also include plastic components. The naming of these components is usually related to their functions, such as large lampshades, turn signal housings, etc. Their main function is to protect the lighting fixtures from damage and provide necessary protection and sealing performance.
2, Manufacturing and Materials of Plastic Parts for Motorcycles
The plastic components on motorcycles are usually manufactured using injection molding and other processes, and the plastic materials used include ABS, PC, PP, etc. These materials have different physical and chemical properties, such as strength, wear resistance, weather resistance, etc., to meet the performance requirements of different components. During the manufacturing process, it is necessary to strictly control the quality of materials, forming process, and subsequent processing to ensure the accuracy and consistency of components.
3, The importance of plastic components for motorcycles
Although the plastic components on motorcycles may seem simple, they play an important role in the overall performance and safety of motorcycles. Firstly, these components provide the appearance and image of the motorcycle, which is one of the important factors that attract consumers. Secondly, they protect the internal structure of motorcycles from external environmental erosion and damage, improving their durability and service life. In addition, some plastic components also have specific functions, such as the casing of lighting and signal equipment, which can protect the lamps from damage and improve cycling safety.
