A motorcycle fairing is a protective shell that covers a motorcycle’s frame to reduce air drag and shield riders from wind. This aerodynamic component primarily helps racing motorcycles and sport bikes achieve better performance while protecting riders from airborne hazards and hypothermia[1].
Purpose and Benefits
The fairing’s main advantage lies in its aerodynamic properties. It reduces drag significantly, which leads to lower fuel consumption and allows higher speeds at lower engine RPMs[1]. Modern fairings only increase frontal area by 5% compared to naked bikes while housing essential components like headlights and instruments[1].
Historical Development
Racing motorcycles started using streamlined designs in the 1920s[1]. The term “fairing” originated from aircraft aerodynamics, where it smoothed airflow between components. The BMW R100RS (1976-1984) revolutionized the industry as the first mass-market motorcycle with a standard full fairing[1].
Types of Fairings
Front Configurations
Dustbin fairings, shaped like aircraft noses, offered excellent drag reduction but were banned in 1958 due to stability concerns[1]. Dolphin fairings replaced them, named for their resemblance to river dolphin snouts[1].
Modern Variations
- Full fairings cover both upper and lower motorcycle sections
- Half fairings extend below handlebars but leave the lower sections exposed
- Quarter fairings (café or bikini fairings) provide minimal wind protection
- Handlebar fairings attach to forks and move with steering[1]
Construction Materials
Primary Materials
ABS plastic dominates modern fairing construction, combining strength and flexibility[1]. Manufacturers use two production methods:
- Injection molding creates uniform, precise pieces
- Compression molding offers a cost-effective alternative[1]
Performance Materials
Fiberglass fairings excel on racetracks, offering repairability and durability. Carbon-fiber-reinforced polymer represents the pinnacle of lightweight construction but commands premium prices[1].
Safety Features
Fairings protect engines and chassis during accidents by sliding on road surfaces instead of critical components[1]. Some track regulations require belly pans to catch fluid leaks, enhancing safety during racing conditions[1].

A motorcycle fairing is a shell placed over the frame of a motorcycle, especially racing motorcycles and sport bikes, to deflect wind and reduce air drag. The secondary functions are the protection of the rider from airborne hazards and wind-induced hypothermia and of the engine components in the case of an accident. A motorcycle windshield will usually be integrated into the design of the fairing.
The major benefit of a fairing on sport touring and touring motorcycles is a reduction in aerodynamic drag, which allows for reduced fuel consumption and permits higher speeds at lower engine rpm, which in turn increases engine life.
A motorcycle may have a front fairing, a rear fairing, a belly fairing, or any combination of these. Alternatively, a single fairing may partially or fully enclose the entire motorcycle, and may even enclose the rider.
