Description:FIELD OF THE INVENTION
[001] The present invention relates to a two-wheeled vehicle. More particularly, the present invention relates to the two-wheeled vehicle having a mounting structure for attaching an electrical component.

BACKGROUND OF THE INVENTION
[002] In conventional two-wheeled motor vehicles, various electrical and electronic loads are supplied with power by an electrical component.The electrical component is under continuous usage while an engine of the vehicle is in running condition. Owing to the continuous usage or functioning, the surface temperature of the electrical component gradually increases, and heat is generated thereof. It has been observed that the generated heat affects the efficiency of the electrical component and disadvantageously reduces the lifecycle of the electrical component.
[003] Generally, in conventional two-wheeled vehicles, the electrical component is disposed near the engine depending on the existing configuration and lay out of the vehicle. This disposition tends to further increase the temperature of the electrical component since hot air passed through the engine is directed to the electrical component.
[004] In another kind of conventional two-wheeled vehicles, the electrical component is disposed below a seat of the vehicle in a confined space. This disposition has disadvantages of making the electrical component to be more susceptible to the heat and also increases the length of an electrical wire connecting a magneto with the electrical component. This increased length of the electrical wire tends to increase in electrical resistance. The increased resistance reduces the AC voltage being supplied to the electrical component. Consequently, the DC voltage being supplied to the electrical loads by the electrical component is also reduced.
[005] It has further been observed that the electrical component requires an amount of space based on the size of the electrical component dependent on the requirements of the electrical loads of the vehicle. Owing to conditions of limited packaging space and design constrains of the two-wheeled vehicle, it remains a challenge in disposing the electrical component inside the vehicle.
[006] In conventional two-wheeled vehicles, the electrical component include a regulator-rectifier unit. The regulator-rectifier unit of the electrical component converts an Alternating Current (AC) voltage generated by the magneto of the vehicle to a Direct Current (DC) voltage. The DC voltage is supplied to each of the electrical and electronic loads of the vehicle for their desired functioning. The electrical component also supply power for charging a battery of the vehicle.
[007] In view of the foregoing, there is a need to provide a two-wheeled vehicle having a structure for mounting the electrical component which aids in cooling the electrical component and overcomes at least the above-mentioned disadvantages.

SUMMARY OF THE INVENTION
[008] In one aspect of the invention, a two-wheeled vehicle is disclosed. The two-wheeled vehicle includes a head tube, a pair of main tubes extending rearwardly and downwardly from the head tube in a front-rear direction of the vehicle.

The vehicle includes a swing arm being swingably mounted on the pair of pivot plates. The vehicle includes a cross member extending in a vehicle width direction between the pair of pivot plates. The vehicle includes an electrical component disposed on the cross member.

[012] In an embodiment, the electrical component, in the front-rear direction of the vehicle, is disposed anterior to a vertical axis. The vertical axis passes centrally between the first end and the second end of the rear suspension unit.
[013] In an embodiment, the electrical component includes a plurality of cooling fins extending in the vehicle width direction.
[014] In an embodiment, the cooling fins are disposed on the electrical component in a direction opposite to a flow of air passing through an internal combustion engine of the vehicle.
[015] In an embodiment, the cross member includes a flange. The flange is adapted to attach a mounting bracket. The electrical component is mounted on the mounting bracket.
[016] In an embodiment, the vehicle includes a cover member for covering the electrical component. The cover member is disposed behind the electrical component in the front-rear direction of the vehicle.
