When first handed a Signet-Q Pro-Tour helmet for evaluation, I was struck by the appearance—all class, obvious fine fit-and-finish, and quality materials. Let me put that sucker on my head and go riding!
After fondling the headgear for awhile, and manipulating the several intake and exhaust covers, I tried it on—uh-oh, a little SNUG! Although the long oval profile welcomed my so-shaped head, things were a little tight, cheek-wise!
Not a problem; this design has peelable layers of foam on the cheekpads—a little layer peeling here, and—I have a really plausibly wearable helmet! The comfort pad in the crown has peelable temple pads also; I removed them for a little more headroom.
As to protection; not included in the evaluation—I’m NOT a crash test dummy! However, Arai has a convincing strategy and policy in the shock energy management department; I felt comfortable and confident this lid would take care of my noggin in the event of a crash, to the extent of today’s technology and design.
In the mid-30 degree (F.) temperature, with high humidity I rode around some. Surprise: No condensation on the clear face shield! The “Pin Lock” system, of two transparent layers with an air volume between them was doing its job. I even pushed the bike around while on foot for a block or so, huffing and puffing, but . . . my vision remained clear; no fog at all.
Riding down the highway, the “wide-screen” viewing angle was useful, checking for highway signs, other motorists, and obstacles like dead skunks in the middle of the road (was this Skunk Convention month?).

Riding in sunlight and in shadow, the “Pro-Shade” tinted visor system proved its worth. In its upright position, the visor works much like the peak on a moto-cross helmet—the head can be tilted to gain the advantage of some shadow, protecting from bright light, like the setting sun. When rotated downward, the darkened visor protects from harsh lighting and its consequent glare.
The tinted visor leaves enough clear visor surface at the bottom, useful, for example, when entering a tunnel on a sunny day—the severe contrast between bright sunlight and dark tunnel can be accommodated by simply tilting the head upward when entering the hole; when exiting, the shock of intense light can be modulated by moving the head to a more erect riding position, taking advantage of the light-filtering lens.
The ventilation system was tested only BRIEFLY, because—all riding was done in the mid-20 to mid-30 degree (F.) range. This test was adequate (well MORE than adequate!) to demonstrate a dramatic, free-flowing ventilation system, especially if all five intake ports, and all exhaust ports are opened. Not to say summer riding offers air conditioning, but—comfort level should be greatly enhanced, over helmets with less generous air circulation.
The vent openings are positive, and easily controllable, even with gloves on, once some familiarity with their location and function is achieved. On-and-off is easy enough, with a conventional twin D-ring strap fastening system.
The transparent shield snaps down with authority, and seals out drafts and dust effectively. NOTE: When riding, Arai helmets are designed to be worn with the shield DOWN, for maximum structural integrity and crash protection.)
I found road and wind noise considerably quieter than with my usual moto-cross style helmets; the cheekpad design and foam density chosen may account for the attenuation. While I had no Blue Tooth speaker to insert, a cheekpad cavity was waiting for one, when available.
Research from company public information, from both American and European distributors, as well as interviews with Arai Helmet (Americas) executives, provided the following content.
Protection:
Protection remains the driver in motorcycle helmet choice. Arai has this base covered, this square checked, with the Signet-Q Pro-Tour headgear, featuring both DOT and Snell Foundation certification. Arai goes beyond these helmet certification agencies’ requirements, applying Arai’s own test criteria to each helmet produced.

The governmental and institutional tests apply shock impact to one single point of each helmet under test, measuring G-force impact transmitted to the head area. But, Arai asks, how can the singular test impact area of interest of these tests be extrapolated to the actual critical impact zones of real-world incidents?
Where, exactly, might the guardrail, the footpeg, the concrete curb, or whatever obstacle encountered, strike the helmet of a motorcycle rider involved in an accident? Arai, accordingly, expands the test impact area to cover any point within, essentially, the hemispherical zone covering the entire top of the rider’s head.
Arai in-house certification, anvil force drop tests probe the entire upper coverage surface of each helmet design; each impact must transfer less than the allowable G-force to sensors in the head area for product acceptance. DOT, Snell, and ECE (European) certification tests use metal head forms striking flat anvils, measuring force impact but not penetration resistance.
Arai adds tests with pointed anvils to insure structural integrity from impact with angular objects. The Signet-Q Pro-Tour helmet’s rigid outer shell features high-density fiberglass and resin Super CLC (Complex Laminate Construction), with excellent strength-to-weight characteristics enhancing protection. The helmet weighs in at about three pounds.
The “Super” fiberglass of the Signet-Q was originally developed for aerospace and military applications. About the same density as ordinary fiberglass, its extension and bending strength is up to 40 % greater than that of typical fibers.
Helmet shells are hand-laminated (signed by the technician), with two layers of super fiberglass fabric sandwiching a layer of special composite fiber used to facilitate production. The thermally-cured fiberglass-and-resin shell’s exceptional strength combines with structural design to increase rigidity: A “Hyper Ridge” surrounds the head opening, stiffening the helmet with negligible weight increase.
Arai’s approach to managing head energy impact involves a “hard” outer shell, and a “soft” energy-absorbing interior layer. Front, side, and rear areas of the one-piece helmet inner shock-absorbing liners are made of different density materials, depending upon the preferred distribution of impact G-loads to various head regions. The geometry of the human head leads to this optimization of protective inner layer materials and design.
Fit:
Protection notwithstanding, no one enjoys wearing a helmet producing pain and discomfort from improper fit. Besides providing five different shell sizes, Arai approaches comfort fundamentally with custom interior sizing options. Further, the Signet-Q’s shell design is “Long Oval” in profile, an advantage to those with long oval head shapes, including me!

Arai’s “Facial Contour System (FCS)” assures a custom fit for each rider. The removable cheek pads have layers of cushioning, “peelable” if the headgear fits too snugly. Each helmet can be fitted to its wearer with these facial contour cheek pads.
Also, the comfort liner cushioning the crown of the head can be customized by peeling off a layer of cushioning in the temple area, if more head-room is needed. Further, cheek pads are available in different thicknesses, if customization beyond the peelable foam layers is needed.
Interior cheek pads, neck roll, and comfort layer can be removed for cleaning. Orange tabs on the cheek pads inform trained first-responders of access points for removing cheek pads without removing the helmet, if desirable during incident management.
Vision:
The Signet-Q Pro-Tour provides an extraordinarily wide field-of-view. Its SAI (“Super Access”) MAX-Vision shield combines the enhanced field of view of the SAI eye port (with 5mm more peripheral view at each side than previous models), with a full eye port cavity to accept the Pin Lock 100% Max-Vision™ lens for larger anti-fog field of view.
Face shield fogging is minimized by the “Pin Lock” lens system. A second transparent layer lies over the face shield, held in place by screws, trapping an insulating volume of air between the two viewing surfaces. This thermal isolation minimizes fogging, reducing the consequent safety compromise of occluded vision.
The chin vent of the helmet’s ventilation system helps dissipate breath condensation; Another shield fogging countermeasure exists in the “breath deflector,” an impervious strip above the wearer’s upper lip. This barrier deflects breath away from the shield and toward the mouth vent, where moist air can be expelled. This component is easily removable, if desired.

Additionally, the Signet-Q features its “Pro-Shade” system pre-installed, shielding the rider from excessive sunlight brightness. A tinted shield fits over the clear face shield, adjustable upward to a helmet peak position (similar to a “motocross” helmet profile), or downward as a sun visor.
Notches in the Pro-Shade plastics insure the eyebrow vents are clear to air flow, regardless of shield position. Pulled forward and lowered over the transparent shield, the wearer’s eyes are protected from sunlight and glare.
The transparent face shield fits the helmet opening tightly, limiting entry of dust, water, and wind. When the shield is opened, small “sliders” on the helmet lift the shield slightly, preventing scratches from shield/helmet shell contact.
Ventilation:
Five closeable air intakes (chin vent with three-position cover, two brow vents and two top vents) help cool a Signet-Q wearer’s head. Two venturi vents and a closable neck roll vent exhaust air from the rear.
All intake and exhaust vents may be closed in cold weather. The aerodynamic design of the inlets and exhausts provide a free-flowing airstream, helping keep the interior fresh and dry, with minimal wind noise. The helmet’s ventilation system also helps dissipate breath condensation.
Bottom Line:
The Arai Signet-Q Pro-Tour helmet will take the rider from the road, through track day, comfortably and safely. The combination of design, materials, testing and quality control produce a road helmet approaching the capability of GP headgear.
I found the deluxe features of the Pin Lock fog-fighting scheme, the fit-enhancing Facial Contour System, the ambient light-management Pro-Shade visor, and the free-flowing ventilation system all meaningful and relevant to a practical road helmet. MSRP: $749.95 AraiAmericas.com
