Description

[Detailed description of the invention] The present invention relates to a motorcycle, particularly a motorcycle in which an engine is suspended on a body frame, a fuel tank is straddled below the engine, and a radiator and its reserve tank are further arranged below the fuel tank. Regarding.

In the above-mentioned motorcycle, if the radiator supported by the body frame is made larger, there will be many restrictions on the layout due to the need to avoid interference between the radiator and the body frame, and the radiator will be ventilated due to the body frame in front of the radiator. There are problems such as the area being reduced.

The purpose of the present invention is to provide a motorcycle with a simple structure that can solve such problems, and its features include an engine suspended on a body frame, a fuel tank straddled above the engine, and a fuel tank placed between the body frames. A radiator is disposed below one side of the fuel tank, and a reserve tank for the radiator is disposed below the other side, and an exhaust chamber of an exhaust pipe connected to the engine is disposed below the reserve tank. The outer surfaces of the tank and the exhaust chamber are covered with a first side cover, and the outer surface of the radiator is covered with a second side cover.

An embodiment of the present invention will be described below with reference to the drawings.

In the following description, "front, rear" and "left, right" refer to the direction of travel of the motorcycle.

A traveling engine E is suspended in the center of the body frame F of the motorcycle, and the vehicle body frame F is suspended on the body frame F above the engine E.
A fuel tank T is mounted so as to straddle the fuel tank T, and a seat S is further mounted behind the fuel tank T.

On the front right side of the vehicle body frame F, a cooling radiator 1 for the engine E is suspended and supported via a support member 2, and on the front left side of the vehicle body frame F, the reserve tank 3 of the radiator 1 is suspended from the support member 2. 4, and the radiator 1 and the reserve tank 3 are arranged in parallel with the vehicle body frame F in between.

An exhaust port 5 of the engine E is open at the front of the engine E, and an exhaust pipe Ex is connected to the exhaust port 5. This exhaust pipe Ex has a large-capacity exhaust chamber 8 interposed between the front and rear exhaust pipes 6 and 7, and the front exhaust pipe 6 is curved in a U-shape and extends to the left side of the vehicle body frame F. . The exhaust chamber 8 communicating with the rear end of the exhaust pipe 6 is located below the reserve tank 3, and the rear exhaust pipe 7 connected to the rear end of the exhaust chamber is located at the rear of the vehicle body frame F. It is growing.

Left and right side covers 9 and 10 are suspended from both sides of the front part of the fuel tank T. The left side cover 9 is fixed to the fuel tank T and the reserve tank 3, and is further attached to an insertion stay 1 provided at the bottom of the back side.
1 is a support piece 12 provided on the outer surface of the exhaust chamber 8
is plugged into and combined with. This left side cover 9 covers the outer surface of the reserve tank 3 and the outer surface of the exhaust chamber 8, and prevents the exhaust chamber 8 from being seen from the outside to improve the appearance and to prevent air from being radiated from the exhaust chamber 8. This is to reduce the discomfort caused to passengers by the hot air.

Further, the right side cover 10 is fixed to the fuel tank T and the radiator 1, and covers the outer surface of the radiator 1.

As described above, according to the present invention, the vehicle body frame F
An engine is suspended on the engine, and a fuel tank T is provided above the engine, and a radiator 1 is placed below one side of the fuel tank T across the body frame F, and a reserve tank 3 for the radiator 1 is placed below the other side.
An exhaust chamber 8 of an exhaust pipe Ex connected to the engine E is arranged below the reserve tank 3, and each outer surface of the reserve tank 3 and the exhaust chamber 8 is covered with a first side cover. 9, the outer surface of the radiator 1 is also
Since the radiator 1, which is relatively heavy and requires a large space, can be centrally placed on one side of the vehicle body frame F, interference between the radiator 1 and the vehicle body frame F can be easily avoided. At the same time, the ventilation area of the radiator 1 can be secured sufficiently wide without being narrowed by the vehicle body frame F. Furthermore, even if the radiator 1 is arranged on one side, on the other side across the vehicle body frame F, a relatively heavy reserve tank 3 and a relatively large capacity exhaust chamber 8 are arranged vertically. The weight balance is good, and each part 1, 3,
The left and right arrangement of 8 is also well balanced. Moreover, since the left and right side covers 9, 10 that cover these parts 1, 3, 8 can be formed in a well-balanced manner to have approximately the same length in the vertical direction, together with the original covering effect of the covers 9, 10, the overall coverage of the motorcycle is improved. The appearance can be significantly improved, and one side cover 9 can be used as a common cover for the reserve tank 3 and the exhaust chamber 8, which makes the structure simpler and contributes to cost reduction.
