A motorcycle intake air guide for feeding an intake air volumetric flow to a motorcycle internal combustion engine includes an unfiltered-air channel, a filtered-air channel, and an air filter therebetween. An intake air guide valve provided in the unfiltered-air channel is configured to change a cross-section of the unfiltered-air channel cross-section. The unfiltered-air channel has a double-flow design at least in sections with a first unfiltered-air partial channel and a second unfiltered-air partial channel which are merged downstream of a steering head of a frame of the motorcycle in a collection region of the unfiltered-air channel. The intake air guide valve is arranged in the collection region, downstream of the first and second unfiltered-air partial channels.
