Abstract: An air intake assembly for a motorcycle provides increased air flow to the carburetor by increasing the intake area of the ducting and placing it out in the air stream facing forward so that a ram air effect is achieved. Increased intake area is provided by dual velocity stacks arranged in an over-and-under vertical orientation positioned directly adjacent the side of the engine to minimize the width of the motorcycle. A compact aesthetically-pleasing assembly is provided which can also increase performance.
