A structure added to a motorcycle primarily for aerodynamic purposes, or for protection of the rider from the elements, is a key component influencing both performance and aesthetics. These components can range from small screens deflecting wind away from the rider’s chest to full enclosures significantly reducing drag and enhancing streamlined airflow. A sport bike with a complete shell exemplifies this structure, minimizing air resistance at high speeds.
The inclusion of such a structure offers several advantages. Improved fuel efficiency, increased top speed, and enhanced rider comfort are notable benefits. Historically, these were primarily seen on racing motorcycles to gain a competitive edge. Over time, they migrated to production models as manufacturers sought to offer enhanced performance and rider experience. In addition to functional benefits, its design contributes significantly to the overall visual appeal of the motorcycle.
