A straddle-type vehicle comprising: a front wheel; a rear wheel; a throttle valve adapted to adjust an amount of air supplied to an engine; a transmission including a plurality of transmission gears; a clutch provided in a power transmission path between the engine and the transmission; a controller adapted to control the engine, the transmission, and the clutch, and during shift-down operation of the transmission, adapted to temporarily restrict power transmission through the clutch and to execute throttle control to increase an engine speed; and a braking system including a front braking device adapted to apply a braking force to a front wheel of the vehicle, and a rear braking device adapted to apply a braking force to the rear wheel of the vehicle; a brake operation member operated by a rider for operating the front braking device of the front wheel, and a brake operation member operated by a rider for operating the rear braking device of the rear wheel, characterized in that the controller includes a first throttle control unit adapted to set a parameter of control of the throttle valve to a first value and executes throttle control according to the first value, where the first value is set so that the engine speed increases to a first speed lower than a shift-down completion speed which is an engine speed at the time when the shift-down operation is completed, and a second throttle control unit adapted to set the parameter of control of the throttle valve to a second value and executes throttle control according to the second value, where the second value is set so that the engine speed increases to a second speed which has a difference smaller than that of the first speed from the shift-down completion speed, and the controller is adapted to select one of the control by the first throttle control unit and the control by the second throttle control unit according to an operating state of the braking system, wherein the controller is adapted to select the control by the second throttle control unit when the brake operation member for operating the front braking device of the front wheel and the brake operation member for operating the rear braking device of the rear wheel are operated; and the controller is adapted to select the control by the first throttle control unit when either one of the brake operation member for operating the front braking device of the front wheel and the brake operation member for operating the rear braking device of the rear wheel is not operated. a front wheel;
