Abstract

There is provided a motorcycle. A side stand is disposed at a side-lower portion of an engine and configured to be rotatable between a using position at which the side stand can be grounded to a ground surface and a retraction position at which the side stand cannot be grounded to the ground surface. An inflow piping is configured to supply cooling water delivered from a water pump to a supercharger. An outflow piping is disposed above the supercharger and configured to return the cooling water having cooled the supercharger to the water pump. The outflow piping is provided to be horizontal or to have an upward gradient from an upstream side toward a downstream side in a state where the side stand is displaced to the using position to be grounded to the ground surface and the engine is inclined toward the side stand-side.

Claims

1. A motorcycle comprising:

an engine;

a supercharger configured to compress combustion air to be supplied to the engine;

a water pump configured to pump cooling water to the engine and the supercharger;

a cooling piping configured to flow the cooling water delivered from the water pump; and

a side stand disposed at a side-lower portion of the engine and configured to be rotatable between a using position at which the side stand can be grounded to a ground surface and a retraction position at which the side stand cannot be grounded to the ground surface,

wherein the cooling piping comprises;

an inflow piping configured to supply the cooling water delivered from the water pump to the supercharger; and

an outflow piping disposed above the supercharger and configured to return the cooling water having cooled the supercharger to the water pump, and

wherein an angle of the outflow piping changes as an orientation of the motorcycle changes from horizontal to an inclined state where the side stand is in the using position,

wherein the outflow piping is provided to be horizontal or to have an upward gradient from an upstream side toward a downstream side in a state where the side stand is in the using position to be grounded to the ground surface and the engine is inclined toward the side stand-side.

2. The motorcycle according to claim 1, wherein the outflow piping is connected to a circulation path of the cooling water, which is disposed above the supercharger.

3. The motorcycle according to claim 2, further comprising:

a radiator configured to cool the cooling water; and

a cooling water flow control unit disposed above the supercharger and configured to serve as the circulation path and to regulate an amount of the cooling water to flow in the radiator in accordance with a temperature of the cooling water,

wherein the outflow piping is connected between the supercharger and the cooling water flow control unit.

4. The motorcycle according to claim 2, wherein a connection part between the outflow piping and the circulation path is provided on the side stand-side.

5. A motorcycle comprising:

an engine;

a supercharger configured to compress combustion air to be supplied to the engine;

a water pump configured to pump cooling water to the engine and the supercharger;

a cooling piping configured to flow the cooling water delivered from the water pump; and

a side stand disposed at a side-lower portion of the engine and configured to be rotatable between a using position at which the side stand can be grounded to a ground surface and a retraction position at which the side stand cannot be grounded to the ground surface,

wherein the cooling piping comprises;

an inflow piping configured to supply the cooling water delivered from the water pump to the supercharger; and

an outflow piping disposed above the supercharger and configured to return the cooling water having cooled the supercharger directly to the water pump, and

wherein the outflow piping is provided to be horizontal or to have an upward gradient from an upstream side toward a downstream side in a state where the side stand is displaced to the using position to be grounded to the ground surface and the engine is inclined toward the side stand-side.
