There is provided a saddle-ridden type vehicle. An air intake piping is connected between an air cleaner and a supercharger. An air outlet piping is connected between the supercharger and an intercooler. An air bypass passage is provided between the air outlet piping and the air intake piping to allow compressed air to escape toward an upstream side of the supercharger without flowing in the supercharger. An air bypass valve is configured to open and close the air bypass passage. The supercharger is disposed in front of the engine. The air cleaner is disposed above the engine. The air intake piping extends in an upper-lower direction in a region ranging from the above of the engine to a front of the engine at one side in a vehicle width direction. The air bypass valve is disposed at the rear of the air intake piping.
