AIR INTAKE CHAMBER FOR SADDLED VEHICLE

A motorcycle includes a supercharger (42) to pressurize an intake air (I) and supplying it to a combustion engine (E) and an air intake chamber (74) disposed downstream of the supercharger (42). The air intake chamber (74) is made of a metallic material and has a capacity (V) of an interior space thereof which is within the range of three to eight times the displacement (X) of the combustion engine. The dimension (L) from an upstream end portion on an inlet side of the interior space of the air intake chamber (74) to a downstream end portion on an outlet side of the interior space of such air intake chamber (74) is chosen to be three or more times the inner diameter (D) of an outlet (73).
