UNDERSTANDING INTERIOR SHAPES
In order to offer the most comfort, a helmet interior must fit snugly around the entire head contour. (This is partly determined by a firm, even pressure felt at all contact points around the liner perimeter, with no pressure points that could become uncomfortable in the future.) Note that having a previous helmet of the same brand, model and size – even if it’s an Arai – may not offer the same fit as a current model or size because the evolution of design and use of new materials can affect the final design and shape.
Attention must be paid to the fit of the model’s shape around the crown of your head – and not with facial fit. (The part that is contacted by a baseball cap’s band, for example, is the crown) Cheek pads in all Arai helmets can be replaced with a size that better suits your facial structure, so the possible need for different cheek pads should only be addressed after the crown is properly sized. All too often, tight OEM cheek pads will result in purchasing a helmet one or even two sizes too big – in effect sizing the face and not the head! The end result will be a loose and noisy helmet, as described above. (Riders with a strong jaw or heavy cheeks should first remove the cheek pads completely in order to not be distracted in determining crown fit.)
DETERMINING YOUR INTERIOR SHAPE
How can you determine which of Arai’s interior shapes is best suited for you? In general, our interiors for the North American markets have an oval shape orientation (somewhat longer from forehead to back of the head or front-to-back and a little narrow from ear to ear or side to side) because most heads tend to be oblong as opposed to round. Our different helmet models vary slightly based on that general Oval shape to accommodate a much wider fit range.
INTERIOR SHAPE: 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.
LONG OVAL HELMET MODELS:
INTERIOR SHAPE: INTERMEDIATE OVAL
- Shorter front-to-back
- A little wider side-to-side than the Long Oval
- This fit package begins the shift from oblong towards round.
INTERMEDIATE OVAL HELMET MODELS:
INTERIOR SHAPR: ROUND OVAL
- Even a little shorter front-to-back
- A little wider side-to-side
- This fit package is represented by our RX-Q model.
