Motorcycle Intake Air Guide for a Motorcycle Internal Combustion Engine

A motorcycle frame, comprising:

• a steering head configured to receive a motorcycle front wheel fork rotatable in the steering head;
• and
• a motorcycle intake air guide configured to feed an intake air volumetric flow to a motorcycle internal combustion engine, including
• a raw-air duct,
• a clean-air duct,
• an intake air guide valve arranged in the raw air duct, and
• an air filter,
• wherein
• the raw-air duct is arranged upstream of the air filter in a flow direction of the intake air volumetric flow,
• the clean-air duct is arranged downstream of the air filter
• the intake air guide valve is configured to be movable to change a cross-sectional area of the raw-air duct,
• the raw-air duct includes a first raw-air subduct and a second raw-air subduct arranged in parallel in the flow direction of the intake air volumetric flow,
• the intake air volumetric flow emerging from the first and second raw-air subducts is merged downstream in a collection region of the raw-air duct, and
• the intake air guide valve is arranged in the collection region, downstream of the first and second raw-air subducts,
• the motorcycle intake air guide is arranged on the motorcycle frame such that the first raw-air subduct and the second raw-air subduct at least partially enclose a steering head region through which the steering head extends through the motorcycle air intake guide between the first and second raw-air subducts.
