Abstract

In a motorcycle having an engine between a front wheel and a rear wheels, functional components (a first radiator, a fuel pump, a rear shock absorber) are arranged, as viewed from the side, on a circumference of a circle with a radius R corresponding to a distance from a crankshaft, serving as a center, to a corner of an oil pan, serving as a part most distant from the engine, to thereby concentrate the functional components of the motorcycle at positions substantially equidistant from the crankshaft of the engine. To achieve a mass concentration toward the vehicle body center of a motorcycle.

Claims

1. A motorcycle comprising:

an engine arranged between a front and a rear wheels; and

a plurality of functional components being arranged, as viewed from the side, on a circumference with a radius corresponding to a distance from a crankshaft of the engine serving as a center, to a part most distant from the engine.

2. The motorcycle according to claim 1, wherein the functional components are a radiator, a fuel pump and a rear wheel shock absorber.

3. The motorcycle according to claim 1, wherein a voltage-current adjusting regulator and a battery are arranged inside the circumference.

4. The motorcycle according to claim 2, wherein a voltage-current adjusting regulator and a battery are arranged inside the circumference.

5. The motorcycle according to claim 1, wherein a discharge port of an exhaust pipe is provided on the circumference.

6. The motorcycle according to claim 2, wherein a discharge port of an exhaust pipe is provided on the circumference.

7. The motorcycle according to claim 3, wherein a discharge port of an exhaust pipe is provided on the circumference.

8. The motorcycle according to claim 3, wherein longitudinal directions of at least one of the plurality of functional components, the regulator, and/or the battery extend substantially along the circumference.

9. The motorcycle according to claim 4, wherein longitudinal directions of at least one of the plurality of functional components, the regulator, and/or the battery extend substantially along the circumference.

10. The motorcycle according to claim 1, wherein the engine is of a V-type.

11. The motorcycle according to claim 2, wherein the engine is of a V-type.

12. The motorcycle according to claim 3, wherein the engine is of a V-type.

13. The motorcycle according to claim 4, wherein the engine is of a V-type.

14. The motorcycle according to claim 5, wherein the engine is of a V-type.

15. A motorcycle comprising:

a frame for supporting a front wheel at a forward position thereof and a rear wheel at a rearward position thereof;

an engine arranged between the front wheel and the rear wheel;

a crankshaft being operatively mounted within said engine; and

a circumference being formed with a radius corresponding to a distance from the crankshaft of the engine providing a center with a plurality of functional components for the motorcycle, being arranged, as viewed from the side, on the circumference with a radius corresponding to a distance from a crankshaft of the engine serving as a center, to a part most distant from the engine.

16. The motorcycle according to claim 15, wherein the functional components are a radiator, a fuel pump and a rear wheel shock absorber.

17. The motorcycle according to claim 15, wherein a voltage-current adjusting regulator and a battery are arranged inside the circumference.

18. The motorcycle according to claim 16, wherein a voltage-current adjusting regulator and a battery are arranged inside the circumference.

19. The motorcycle according to claim 15, wherein a discharge port of an exhaust pipe is provided on the circumference.

20. The motorcycle according to claim 16, wherein a discharge port of an exhaust pipe is provided on the circumference.
