Sharing much in common with its pricier siblings, the RF employs Shoei's Advanced Integrated Matrix construction process, or AIM+. In English, that means both organic and inorganic fibers are combined with fiberglass to create a lightweight, strong outer shell that can be given a "unique" shape. Staunch traditionalist that I am, my new lid's slightly angular shape took some getting used to, particularly the rear wing spoiler. But then again, I wanted to wear it, not sit and stare at it. Besides, Shoei tells me that the aerodynamics of the wind-tunnel-tested design result in greater stability at high speeds, reducing buffeting and rider fatigue. After wearing the thing, I'm forced to agree, proving, I suppose, that form does follow function.
