Motorcycle fairing
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 single piece, streamlined shell covering the front half of a motorcycle resembling the nose of an aircraft, sometimes referred to as torpedo fairing.
[5] Other reasons cited for the ban were to ensure adequate steering range (lock-to-lock) and stability in crosswinds.
FIM regulations forbid streamlining beyond the wheel spindles and require the rider's arms and legs to be visible from the side.
[5] However, Peter Williams was permitted to give his 1973/74 JPS Norton a Peel-type fairing incorporating handlebar blisters which helped to reduce the drag coefficient to 0.39.
[7] This was called so because, in early models, the front wheel mudguard streamlined with the rising windshield part of the fairing resembled the river dolphin's snout from the side view.
The fairing on a race or sport bike is meant as an aerodynamic aid, so the windscreen is rarely looked through.
It is attached only to the forks or yokes, encompassing the headlight and instruments, and varying portions of the handlebars, and moves with them as the bars are turned.
Some track day or racing rules require belly pans to catch leaked fluids.
[11] Acrylonitrile butadiene styrene (ABS) plastic is commonly used in original equipment sport bikes and certain aftermarket fairing manufacturers due to its strong, flexible and light weight properties.
The advantage of ABS over other plastics is that it combines the strength and rigidity of acrylonitrile and styrene with the toughness of polybutadiene rubber.
