Side panels protect important components such as the engine and electronics from dirt, splashing water and stone chips. They are attached to the sides of the frame and contribute to the overall structure and aerodynamics of the vehicle.
Their usually streamlined design reduces drag and improves driving stability, especially at high speeds. Side panels are often made of lightweight, robust materials such as plastic, fibreglass or carbon, and their appearance can be adapted to match the style of the motorcycle.
In addition, they give the motorcycle a sporty, cohesive look and contribute to customisation.
