Please advise if the plastic white component mounted below the number plate on these motorcycles is or is not an Aerodynamic device that could afford an advantage at 100+ MPH over an identical motorcycle without this device? Users claim it is to keep dirt out of the hole in the bottom of the neck of the triple trees that hold the forks. I submit, if that be the case, why not just simply use a piece of lightweight tape instead of this heavier part? The components in question are below the number plates on the #4 and #59 Motorcycles. I submit they re-direct air downward, thus avoiding the fins of the cylinder on the engine, and force it to run under the chassis, where it creates far less drag than running through the fins on the cylinder. http://amaproracing.com/images/content/story/Springfield_featured.jpg [Broken] American Motorcyclists Association AMA in Daytona Florida Tech Directors state that they feel this device affords zero aerodynamic advantage. And they also contend that it is not a fender to keep dirt off the lower Triple Trees. We are trying to determine just what the hell this thing is then? Thanks in advance for your input.
