Motorcycle fairings and body work are often replaced when fixing racing and sports motorcycles, as well as other types. Many times, people buy their fairings where they purchase other used motorcycle parts. Full fairings cover the upper and the lower parts of the motorcycle frame, and do a good job at keeping the wind and rain off the rider. In winter, this helps to keep the rider warm too. Motorcycle fairings make the bike more aerodynamic, thus increasing its speed, and also help to protect the engine in case of an accident. Since fairings normally come in one piece, the work required to replace them is minimal.
