DESC:TECHNICAL FIELD
[0001] The present subject matter relates generally to a two-wheeled motor vehicle, and more particularly to a visor for the two-wheeled motor vehicle.
BACKGROUND
[0002] Generally, in a two-wheeled vehicle a frame assembly extends rearward from a head tube. The frame assembly is a structural member and acts as a skeleton for the vehicle that supports the vehicle loads. A front portion of the frame assembly connects a front wheel through one or more front suspension(s). The frame assembly extends towards a rear portion of the vehicle. A rear wheel is connected to a frame assembly through one or more rear suspension(s). An engine assembly is mounted to the frame assembly of the vehicle. The engine assembly is functionally connected to the rear wheel, which provides the forward motion to the vehicle. Typically, plurality of panels is mounted to the frame assembly of the vehicle that covers various vehicle parts mounted thereon.
[0003] Typically, body panel of two-wheeled motor vehicles have a front structure that covers a front portion of the vehicle, and a rear structure that covers a rear portion of the vehicle. Such front and rear structures that constitutes body panel of the vehicle are often referred to as cover assemblies that cover one or more vehicle frame members. These typically known cover assemblies provide necessary aesthetic appeal to the vehicle.
[0004] Generally, known body panel for motorcycles, include a visor member mounted to the front cover assembly of the vehicle. Such visors act as wind shield for the rider, especially in case of high speed applications. Visors are essential part of such high speed motorcycles as the vehicle is made to pass through a gush of air stream, which when not shielded and guided away could well be hitting the rider’s face. There have always been constant efforts taken to route such air stream above the head of the rider thereby allowing the rider with an unobstructed ride.

DETAILED DESCRIPTION
[00011] Typically, body panel structures of known two-wheeled motor vehicles merely serve the aesthetic purpose of the vehicle and often may hamper the functional requirements of the vehicle, especially, when the vehicle is meant for high speed applications. For instance, the shape and material of the front structure of the body panel is critical in deciding the aerodynamic performance of the vehicle that could enable the vehicle to move at high speeds without being affected by the drag coefficient.
[00012] For instance, in typical high speed motorcycles, visors are provided to deflect air above the head of the rider. However, a visor with simple flat profile may not be able to guide the airflow appropriately during all vehicle orientations. More particularly, for instance, whenever banking angle is increased during bends, a visor with flat profile may not be sufficient to divert the flow of air. Thus, the overall profile of the visor structure becomes all the more important for optimally diverting air during high speed riding, at the same time for providing enhanced ease of riding for the rider.
[00013] Moreover, there is also a challenge to ensure that the visor structure does not vibrate, bend, or break while riding in high speed conditions. For instance, improper mounting of the visor structure could cause the visor structure to vibrate at one end, which may cause the visor structure to emanate unwanted noise. Similarly, improper thickness of the visor structure at the edges also lead to bending of the visor structure, in worst scenario, may also lead to breaking of the visor structure. Hence, there is also a challenge to provide optimal mounting of the visor structure, in addition, the profile of the visor structure is required to withstand high impact of air.
[00014] The present subject matter provides a visor for a two-wheeled vehicle that overcomes the above stated problems existing in the visor structure known in the prior arts. In an embodiment, the present subject matter provides a visor having an intermediate bulged profile that allows diversion of air on either side during all vehicle orientations.
[00015] In an embodiment, the visor of the present subject matter includes a triangular shaped lower region that is tapered and projecting downwards towards a front fairing assembly. The lower region of the visor includes a left side portion and a right side portion. In one embodiment, both the left side portion and the right side portion of the visor’s lower region are mounted along the adjoining periphery of the front fairing assembly. Further, in one embodiment, the visor structure of the present subject matter has a first bulged middle portion. In an embodiment, the first bulged middle portion of the visor structure enables optimal diversion of air, for example, during bending of the motorcycle, especially, at high speeds. The first bulged middle portion of the visor structure ensures that the air is made to pass above the head of the rider during all postures of the rider, for example, when the rider is sitting upright, crouching in front, leaning towards back, bending on either LH side or RH side and the like.
[00016] In an embodiment, the visor structure of the present subject matter has an upper region. In an embodiment, the upper region of the visor structure has a second bulging portion. For example, the second bulging portion is disposed above the first bulged middle portion with a depression in between both the first and the second bulged portions. In an embodiment, the upper region includes an extended end portion on either side of the second bulged portion. The extended end portions prevent the visor structure from bending or breaking during high speed applications. In an embodiment, the extended end portions also enable elimination of vibration of the visor structure.
[00017] The present subject matter is aimed at addressing the aforementioned and other problems in the prior art. The aforesaid and other advantages of the present subject matter would be described in greater detail in conjunction with the figures in the following description.
