A motorcycle that includes a frame, a steering assembly, front and rear wheels, and an engine/transmission assembly. The motorcycle also includes an engine cooling fan that creates a flow of cooling air across the engine. The motorcycle also includes an air box and an air box delivery system that provides air to the air box. The air box is mounted to the frame and includes an air filter, an inlet located outside of the filter, and an outlet located inside of the filter such that air entering the inlet passes through the filter before exiting through the outlet. The air box delivery system includes a passage that is substantially perpendicular to a longitudinal axis of the frame and in fluid flow communication with the air box, the passage directing the flow of air upwardly into the air box.

Motorcycle engine cooling system

The present invention includes a motorcycle frame that has a steering head and a fuel storage unit that is adapted to contain motorcycle fuel. A separating wall is disposed between the fuel storage unit and the steering head to substantially prevent fluid communication between the fuel storage unit and the steering head. The steering head includes a stress focusing structure for separating the steering head from the fuel storage unit and leaving the separating wall substantially intact to contain fuel within the fuel storage unit in response to a predetermined force being applied to at least one of the steering assembly and the front wheel.
