Claim:
An assembly for admitting combustion air into the engine of a motorcycle, the assembly comprising: an air filter; a tube for taking air from the air filter to the engine; a housing designed to be mounted in the top portion of the motorcycle and forming a support for the air filter; an air inlet module fitted to the housing and having at least one shutter movable between a first position in which it shuts an inlet for allowing air to flow towards an inside zone of the housing, situated upstream from the air filter, and a second position in which it allows air to flow into the air opening towards the inside zone of the housing; control means for controlling the movements of the shutter between its first and second positions; and assembly means for mounting the assembly at the top portion of the motorcycle; wherein the air filter is generally annular in shape, wherein, when it is disposed inside the housing, it subdivides the inside volume of the housing into a radially inner chamber and a radially outer chamber, wherein the radially inner chamber is fed with air through the air inlet module, and wherein the radially outer chamber forms around the air filter a chamber for stabilizing the flow of air downstream from the air filter.
