Abstract: A saddle-ridden vehicle includes: an engine; a radiator unit which is disposed in front of the engine and cools cooling water sent from the engine; a supercharger which is disposed between the engine and the radiator unit and compresses air for combustion to be supplied to the engine; and a reservoir tank which is connected to the radiator unit and stores cooling water to flow into the radiator unit, the radiator unit includes a top radiator disposed in top-front of the engine and a bottom radiator disposed below the top radiator, and the reservoir tank is disposed below the supercharger between the engine and the bottom radiator.

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.

Abstract: There is provided a saddle-ridden type vehicle. An oil cooler cools engine oil to be supplied to an engine. A supercharger compresses combustion air to be supplied to the engine. A water pump pumps cooling water to the engine and the supercharger. A cooling piping flows the cooling water delivered from the water pump. A first inlet piping supplies the cooling water to the oil cooler. A second inlet piping is disposed in parallel with the first inlet piping and supplies the cooling water to the supercharger. A first outlet piping extends upward from the oil cooler and returns the cooling water to the water pump. A second outlet piping extends upward from the supercharger and returns the cooling water to the water pump. The first outlet piping and the second outlet piping converge above the oil cooler and the supercharger.

Abstract: A saddle-ridden vehicle includes: a pair of frame members which are disposed on one side and on other side in a vehicle width direction so as to extend in a vehicle front-rear direction; an engine which is disposed between and supported by the pair of frame members; an air cleaner which cleans air for fuel combustion; a supercharger which compresses the air cleaned by the air cleaner; an intercooler which cools, using a cooling wind, the air compressed by the supercharger and supplies resulting air to the engine; and an exhaust wind duct which determines a discharge position or a discharge direction of the cooling wind discharged from the intercooler, and the exhaust wind duct is disposed above the engine on the one side in the vehicle width direction and extends to rear of the engine.
