The purpose of a rear fender on a motorcycle is to provide protection and coverage for the rear wheel. It is typically a metal or plastic component that extends from the frame or rear subframe of the motorcycle and wraps around the rear wheel.
The main functions of a rear fender include:
Protection: The rear fender helps shield the rider and passenger from dirt, water, and debris that may be thrown up by the rotating rear wheel. It prevents these elements from directly hitting the rider, which could be uncomfortable or potentially hazardous.
Safety: The fender also plays a role in safety by preventing loose clothing, shoelaces, or other objects from getting caught in the moving parts of the rear wheel. This helps avoid accidents or mechanical damage.
Aesthetic Appeal: Rear fenders often contribute to the overall design and appearance of the motorcycle. They can be customized or styled to enhance the bike's aesthetics, reflecting the owner's personal taste or the overall design theme of the motorcycle.
It's worth noting that some motorcycles, particularly sport bikes or custom-built bikes, may have a minimal or no rear fender at all for the sake of style. However, in most standard motorcycles, a rear fender serves important functional purposes.
