Motorcycle windshield

Motorcycle accessories are features and accessories selected by a motorcycle owner to enhance safety, performance, or comfort, and may include anything from mobile electronics to sidecars and trailers. An accessory may be added at the factory by the original equipment manufacturer or purchased and installed by the owner post-sale as aftermarket goods.

The most prominent of the plastic or fibreglass shells covering parts of the motorcycle is the "fairing". In practice, this may blend almost seamlessly with engine panels or wheel covers/mudguards (which in some cases will be painted or plated metal). These systems act to protect the rider from some or all of the weather, may improve aerodynamics (reducing drag), and are an important styling element.

Modern fairings, mostly designed specifically for each motorcycle and fitted as original equipment by the manufacturer, have eliminated the aerodynamic and structural failings of early add-on fairings. Both sports and tourer versions improve (sometimes very considerably) the rider's comfort in cold and wet weather and even "bikini" versions protect the vulnerable crotch region from water ingress.

Also called windshields or screens, windscreens can be built into a fairing or be attached to an otherwise unfaired bike. They are usually made from transparent high-impact acrylic plastic. They may be shaped specifically to direct air flow over or around the head of the rider even if they are much shorter than the seated rider. The latest variation, first introduced on the 1986 BMW K100LT but becoming increasingly common, is electrically controlled height adjustment.

Since motorcycles lack climate control or full protection from the wind, some manufacturers offer heated seats or hand grips to relieve the discomfort of low temperatures experienced during night riding or the colder months. They can also be added on as aftermarket accessories and are powered by the bike's electrical system.

Some touring motorcycles, such as the Honda Gold Wing, have louvred vents in the fairing which redirect warm air from around the engine or exhaust toward the rider. These motorcycles may also feature vents for cooling the rider.
