Determining Your Interior Shape
How can you determine which of Arai's three interior shapes is best suited for you? In general, the North American markets have an oval shape orientation (somewhat longer front-to-back and a little narrow from side-to-side) because that is the shape that tends to fit most of us. Arai's different models then vary slightly based on that general Oval shape to accommodate a much wider fit range.
Long Oval
Very long front-to-back, very narrow side-to-side
Offers additional forehead room for those who find that most helmets have pressure points in the forehead.
Intermediate Oval
A little shorter front-to-back and a little wider sideto-side than the Long Oval
Standard shape that tends to fit most of North American head shapes.
Round Oval
Even a little shorter front-to-back and a little wider side-to-side
For riders whose heads are slightly wider rather than elongated.
