The Signet-X is the latest long-oval variant of Arai's standard bearer "X" series of premium full-face helmets. This product line is the result of decades of iterative development, resulting in high-performing, fastidiously finished fiberglass helmets that are handmade at the company's factory in Japan. Classic design; proven form and function.
There are a few design details that Arai bakes into all its helmets, and they're all present here.
Round exterior head shape. Known as the R75 concept, Arai very consciously refrains from contours in the outer shell of its helmets that violate the 75-degree -radius rule. Why? Because hard edges could catch on pavement when the helmet is sliding down the road at highway speeds.
Kevlar reinforcement. Ever seen a helmet that's been laid down at speed? Pavement makes for a hell of a belt sander. Arai anticipates this and incorporates an internal belt of abrasion-resistant Kevlar inside the fiberglass shell of every helmet it makes to provide added impact/puncture and resistance to being sawed through by passing asphalt.
Exterior shield pods. Following with Arai's focus on keeping a round-as-possible exterior shape, and with prioritizing energy absorption over all else, Arai's telltale exterior shield pods exist to elimiate the need to carve into the spherical integrity of the helmet. This design both allows for more EPS liner between the wearer and the road, and allows for the helmet to better glance off passing objects.
Shell integrity. Notice that all Arai helmets forgo the classic vents drilled directly through the "forehead" of the helmet. Instead, Arai builds intake ports directly into its face shields.
All Snell all the time. Also see, no drop-down sun visors, ever. Because this would violate the Snell safety standards that Arai is so dedicated to (having a void between the shell and EPS liner to house a sun visor is an automatic disqualification for the Snell standard.)
Custom fit. Last but certainly not least, Arai is the only company offering multiple interior-fit shapes to better address the infinite variety of riders’ head shapes and sizes.
For intermediate oval, check out either the all-new Regent-X, the tracker-inspired Defiant-X, or the classic flagship track model, the Corsair-X.
For Round-Oval head shapes, check out the Quantum-X.
While we find that the bell curve of the North American market fits the intermediate-oval head-shape, it's invaluable to be able to offer Arai's full catalog, because it doesn't matter how much you like the looks or features of any given helmet—fit should always be the first and foremost consideration.
The Signet-X has Arai's "Long Oval" (LO in Araispeak) interior fit shape. Longer front-to-back and a more narrow side-to-side (as compared to Intermediate Oval/IO), or Round Oval (R/O).

- VAS MAX Vision face shield provides excellent visibility in all seasons thanks to the included Pinlock insert
- Neckroll is removable and has additional exhaust channels to remove interior heat
- Cheek pads with Emergency Release Tabs
- QVF & QVR upper ventilation ducts look familiar but offer more adjustment and better flow through performance
- PB-SCLC Shell has superb tensile strength due to a variety of carefully-positioned materials and light weight resin
- Includes clear Pinlock insert
- Snell and DOT approved
