Abstract

A motorcycle includes a muffler assembly including a muffler and a muffler cover arranged on one side of a rear wheel in a lateral direction. The motorcycle also includes a housing box resembling the muffler assembly and arranged substantially parallel to the muffler assembly on the other side of the rear wheel in the lateral direction. The housing box has a shape substantially similar to a shape of the muffler assembly, thereby forming a pseudo muffler assembly or replica muffler assembly.

and a pair of left and right rear side covers disposed below the seat;

wherein left and right lateral portions of the body frame are covered with said left and right rear side covers below the seat;

wherein the muffler assembly is arranged under one of said left and right rear side covers;

and wherein the housing box is arranged under the other of said left and right rear side covers.

4. A motorcycle according to claim 2, further comprising a seat attached at a rear portion of the body frame;

and a pair of left and right rear side covers disposed below the seat;

wherein left and right lateral portions of the body frame are covered with said left and right rear side covers below the seat;

wherein the muffler assembly is arranged under one of said left and right rear side covers; and

wherein the housing box is arranged under the other of said left and right rear side covers.

5. A motorcycle according to claim 1,

wherein said housing box comprises:

a box body having an opening formed therein at an upper portion thereof, said opening being operable open from the upper and outer side portions of said box body; and

a lid having a substantially L-shaped cross section, said lid being operable to close and open said opening of the box body, and being attached/detached in a vehicle-width direction for covering the box body;

wherein a shape of said lid is substantially similar to a shape of the muffler cover; and

wherein a color of said lid is substantially similar to a color of said muffler cover.

6. A motorcycle according to claim 2, wherein said housing box comprises:

a box body having an opening formed therein at an upper portion thereof, said opening being operable open from the upper and outer side portions of said box body; and

a lid having a substantially L-shaped cross section, said lid being operable to close and open said opening of the box body, and being attached/detached in a vehicle-width direction for covering the box body;

wherein a shape of said lid is substantially similar to a shape of the muffler cover; and

wherein a color of said lid is substantially similar to a color of said muffler cover.

7. A motorcycle according to claim 3,

wherein said housing box comprises

a box body having an opening formed therein at an upper portion thereof, said opening being operable open from the upper and outer side portions of said box body;

and

a lid having a substantially L-shaped cross section, said lid being operable to close and open said opening of the box body, and being attached/detached in a vehicle-width direction for covering the box body;

wherein a shape of said lid is substantially similar to a shape of the muffler cover; and

wherein a color of said lid is substantially similar to a color of said muffler cover.

8. A motorcycle according to claim 1, further comprising an ABS modulator disposed in said housing box, wherein said ABS modulator is operable to execute antilock braking control during vehicle operation.

9. A motorcycle according to claim 2, further comprising an ABS modulator disposed in said housing box, wherein said ABS modulator is operable to execute antilock braking control during vehicle operation.

10. A motorcycle according to claim 3, further comprising an ABS modulator disposed in said housing box, wherein said ABS modulator is operable to execute antilock braking control during vehicle operation.

11. A motorcycle according to claim 5, further comprising an ABS modulator disposed in said housing box, wherein said ABS modulator is operable to execute antilock braking control during vehicle operation.

12. A motorcycle comprising

a body frame;
