2006 FJR1300A/E - AIR Management System

What is the Air Management System?

The air management system is a series of new features on the 2006 FJR that work to keep the rider comfortable by managing the way that air flows around and through the motorcycle as it moves down the road. There are two main elements of the Air Management System: the first is designed to direct hot air away from the rider and motorcycle keeping the rider cool. The second is designed to direct cool air around the rider, making for a more comfortable ride at speed.

[SIZE=12pt]By looking at this picture which way should the vents go for less heat on the rider? [/SIZE] :yahoo:

Heat Management

The heat management system was created using computer simulation and wind tunnel testing and is based on the principles of fluid mechanics.

Part of the heat management system is the use of a new curved radiator with twin ring fans that work to push the majority of air, heated as it passes through the radiator, out the sides of the motorcycle and away from the rider. In addition, the heat management system directs cool air through a vent above the radiator. This cool air mixes with the warm air that has passed through the radiator and mixed air then passes below a new formed heat shield located above the engine. This mixed air then exits the motorcycle below the engine.

The heat management system also directs low temperature air through vents on the sides of the headlights. This cool air enters the area between the fairing and frame creating a high pressure area. This high pressure pushes the air through a cool air inlet at the front of the frame. The cool air then passes above a new formed heat shield located above the engine and absorbs any heat that escapes above the heat shield. The air then exits the motorcycle between the fairing panels below and behind the rider.

Rider Airflow Management

The rider airflow management also manipulates air pressure to ensure the rider is comfortable. Two new vents located at the base of the windshield are opened when the windshield is in the highest position. These vents feed air up the rear side of the windshield to dampen the air vortex that is formed as air passes over the top of the windshield. This reduces helmet buffeting.

In addition, a new vent located in the fairing below the windshield feeds air through the fairing and out a vent located below the instruments to reduce the low pressure area behind the windshield. This reduces the helmet pulling sensation that most motorcycles experience when the shield is up. Adjustable side vents also allow the rider to direct warm air on or away from their legs, depending on outside temperature.

It all looks pretty clear cut to me, and the picture supports it. When the side vents are out, they deflect the hot engine air away from the rider.

:yahoo: I found an old batwing in the dump, cut it in half, painted it hi-viz and caulked one half on each side of the vents, much cooler but it gets stuck backing out of the kitchen. By the by, Mr. Yamaha says you are all right and that is proof positive of the superior advances by Yamaha. No matter where you put the vents, they are there. Prove Fact!

:glare: B) B) B) B) B)

Results of my testing:My bike is faster with the panels out.

With one panel open and one closed, it will turn in a circle.

Next test: Solenoid activated panels for air brakes.
