Motorcycle fairing adjustment member and assembly and method of adjusting a motorcycle fairing

## Abstract

A motorcycle fairing adjustment assembly, a motorcycle fairing adjustment member, and a method of adjusting a motorcycle fairing are disclosed. The motorcycle fairing adjustment member includes an outer side configured for mounting to an inner fairing member of a motorcycle, an inner side configured for mounting to a fairing bracket extending longitudinally forward from a neck portion of a motorcycle frame, and an adjustment angle formed by the outer side and the inner side. The adjustment angle adjusts an angle of the inner fairing member relative to the motorcycle frame.

## Background
BACKGROUND
Some motorcycles include a front fairing assembly located near a top portion of the front fork assembly. The front fairing assembly may include one or more headlamps, turn signals, gauges or other instrumentation, or one or more mirrors, or a combination thereof, and is designed to be angularly aligned along a preferred longitudinal or horizontal axis. When the rake angle of the neck portion of the motorcycle frame is adjusted, the front fairing assembly may be undesirably tilted or rotated upward relative to the preferred longitudinal or horizontal axis. Further, a front fairing assembly may have an undesirable angular alignment or position without any adjustment of the rake angle of the fork assembly. Such angling or positioning of the front fairing assembly may adversely affect aerodynamic drag of the motorcycle, motorcycle operator or passenger ergonomics and/or safety, and/or aesthetic appearance of the motorcycle.
Therefore, there exists a need for a motorcycle fairing adjustment member, a motorcycle fairing adjustment assembly, and a method of adjusting a motorcycle fairing that conveniently and reversibly reduces aerodynamic drag and improves the ergonomics, safety, and aesthetic appearance of the motorcycle.

The fairing adjustment member comprises an inner side and an outer side forming an adjustment angle adjusting an angle of the inner fairing member relative to the fairing bracket.
In accordance with an additional embodiment of the present disclosure, a motorcycle fairing adjustment member is provided. The motorcycle fairing adjustment member includes an outer side configured for mounting to an inner fairing member of a motorcycle, an inner side configured for mounting to a fairing bracket extending longitudinally forward from a neck portion of a motorcycle frame, and an adjustment angle formed by the outer side and the inner side. The adjustment angle adjusts an angle of the inner fairing member relative to the fairing bracket.
In accordance with an additional embodiment of the present disclosure, a method of adjusting a motorcycle fairing is provided. The method includes providing a fairing adjustment member having an outer side and an inner side forming an adjustment angle, providing a fairing bracket extending longitudinally forward from a neck portion of a motorcycle frame and having a fairing bracket outer surface, providing an inner fairing member having an inner fairing member inner surface, coupling the fairing adjustment member to the fairing bracket at the fairing bracket outer surface, and coupling the inner fairing member to the fairing adjustment member at the inner fairing member inner surface such that an angle between the inner fairing member inner surface and the fairing bracket outer surface corresponds to the adjustment angle of the fairing adjustment member.

The motorcycle fairing 22 includes an inner fairing member 24 with an inner fairing member inner surface 26 in the embodiment shown. The motorcycle fairing 22 of an embodiment further includes an outer fairing member 28, as illustrated in FIG. 3. Although the present disclosure describes an inner fairing member 24 and an outer fairing member 28, the existence of an inner fairing member does not require the existence of an outer fairing member and the existence of an outer fairing member does not require the existence of an inner fairing member. A fairing bracket 30 is located at or adjacent to a neck portion 32 of the frame 14 in an embodiment. The fairing bracket 30 includes a fairing bracket outer surface 34. The fairing adjustment assembly 12 of an embodiment includes one or more headlamps 36. In one or more embodiments, the fairing adjustment assembly 12 includes one or more gauges or other instrumentation (not shown), one or more turn signals (not shown), one or more mirrors (not shown), headlight(s) (not shown), and/or a windscreen (not shown). The fairing bracket 30 extends longitudinally forward from the neck portion 32 of the motorcycle frame 14 as shown in FIGS. 1-3. The inner fairing member 24 at least partially wraps around the fairing bracket 30 in the embodiment illustrated in FIG. 3. In another embodiment, the inner fairing member 24 extends longitudinally rearward to partially enclose and/or partially obscure the fairing bracket 30 and/or the neck portion 32 of the frame 14. In another embodiment, the inner fairing 24 is disposed adjacent to the fairing bracket 30 and/or the neck portion 32. The fairing adjustment assembly 12 further includes a fairing adjustment member 38 disposed between the fairing bracket 30 and the inner fairing member 24. The fairing adjustment member 38 of an embodiment is generally wedge-shaped. The fairing adjustment member 38 includes an inner side 40 and an outer side 42 forming an adjustment angle θ1. The adjustment angle θ1 adjusts an angle and/or position of the inner fairing member 24 relative to the motorcycle frame 14, neck portion 32, or fairing bracket 30. In one or more additional embodiments, the adjustment angle θ1 adjusts an angle and/or position of one or more of the outer fairing member 28, gauges or other instrumentation (not shown), one or more turn signals (not shown), one or more mirrors (not shown), headlight(s) (not shown), and/or a windscreen (not shown).
In an embodiment, a rake angle of the neck portion 32 is adjusted or modified to form a rake adjustment angle θ2 of the neck portion 32, as indicated in FIG. 1. The rake adjustment angle θ2 of the neck portion 32 refers to the difference between an adjusted or modified rake angle of the motorcycle frame 14 and the original rake angle of the motorcycle frame 14 before adjustment or modification. The rake adjustment angle θ2 of an embodiment corresponds with the adjustment angle θ1 of the fairing adjustment member 38. In an embodiment, a method of the present disclosure includes removing the neck portion 32 from the motorcycle frame 14. Such removal may include, without limitation, cutting the neck portion 32 off of the motorcycle frame 14. An unadjusted neck portion position 44 is illustrated in FIGS. 1 and 2 and refers to the position or angle of the neck portion 32 prior to adjustment or modification.
