Motorcycle
A motorcycle is provided having an engine disposed between a front wheel and a rear wheel and functional components, e.g., a first radiator, a fuel pump, a rear shock absorber, etc., 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 of the engine most distant from the crankshaft, to concentrate the functional components of the motorcycle at positions substantially equidistant from the crankshaft of the engine whereby a mass concentration toward the vehicle body center of a motorcycle is achieved.
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 of the engine most distant from the crankshaft.
2. The motorcycle according to claim 1 , wherein a voltage-current adjusting regulator and a battery are arranged inside the circumference.
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 1 , wherein a discharge port of an exhaust pipe is provided on the circumference.
5. The motorcycle according to claim 2 , wherein a discharge port of an exhaust pipe is provided on the circumference.
6. The motorcycle according to claim 2 , wherein the longitudinal directions of at least one of the plurality of functional components, the regulator, and/or the battery extend substantially along the circumference.
7. The motorcycle according to claim 3 , wherein the longitudinal directions of at least one of the plurality of functional components, the regulator, and/or the battery extend substantially along the circumference.
8. The motorcycle according to claim 1 , wherein the engine is of a V-type.
9. The motorcycle according to claim 1 , wherein the engine is of a V-type.
10. The motorcycle according to claim 2 , wherein the engine is of a V-type.
11. The motorcycle according to claim 3 , wherein the engine is of a V-type.
12. The motorcycle according to claim 4 , wherein the engine is of a V-type.
13. 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;
a circumference being defined by a radius corresponding to a distance from the crankshaft of the engine serving as a center to a part of the engine most distant from the crankshaft, and
a plurality of functional components for the motorcycle being arranged, as viewed from the side, on said circumference.
14. The motorcycle according to claim 13 , wherein a voltage-current adjusting regulator and a battery are arranged inside the circumference.
15. The motorcycle according to claim 13 , wherein a voltage-current adjusting regulator and a battery are arranged inside the circumference.
16. The motorcycle according to claim 13 , wherein a discharge port of an exhaust pipe is provided on the circumference.
17. The motorcycle of claim 1 , wherein the functional components further include components disposed substantially along the circumference in the longitudinal direction.
18. The motorcycle of claim 17 , wherein the functional components include the rear wheel shock absorber, the battery, the regulator, and the fuel pump, said functional components extending in a tangential direction relative to the circumference.
19. The motorcycle of claim 18 , wherein the battery and the fuel pump are disposed at positions substantially point-symmetrical relative to each other and with respect to the axis of the crankshaft of the engine.
20. The motorcycle of claim 1 , wherein a first radiator, a fuel pump, a rear shock absorber, and a downstream exhaust pipe are disposed on said circumference, and a second radiator, a regulator, a battery and a downstream exhaust pipe are disposed along the circumference in the longitudinal direction.
