Arai Signet-Q US Flag Black Frost Helmet

The Arai Signet-Q (the long-oval shaped cousin to the RX-Q) is the product of a racing lineage going back to the late 1970’s. Since Arai’s inception, their RX Line of helmets has set an international standard for rider comfort and safety. The Signet-Q is perfection incarnate, blending modern materials and safety features with decades of knowledge and racing heritage. The result are features like an eyeport designed to maximize peripheral vision, an aerodynamically tuned outer shell and a beautifully crafted and ultra comfortable liner. All these features, combined with industry-leading protection, provide riders with an unmatched level of safety and comfort.

A longer shell shape on the Arai Signet-Q Helmet gives 5mm more space front to back allowing for a larger number of heads to fit comfortably. The shape of the Arai Signet-Q Helmet releases forehead pressures and eliminate hot spots for a more comfortable fit every time.  This shape works best for riders with a long oval headshape.


  • Both the top vent set and side exhaust cowls are direct carryovers from the RX-Q 
  • Brow vent ducting redirects to flow air across the temples
  • DDL-4 exhaust vent to the 10mm wider eye port (5mm on each side)
  • Long Oval Fit
  • SAI "MAX-Vision Brow Vent" shield
  • Clear Pinlock Max-Vision Brow Vent Pinlock lens included
  • Elongated shell adds 5mm from front to back
  • Long-Oval shape helps prevent “Hot-Spot”
  • Multi-Density Single piece EPS liner
  • Removable, replaceable, washable interior
  • Dry-Cool Surface material for rapid displacement of heat and moisture away from your head and into the ventilation airflow for added comfort while riding and a quick dry between rides
  • 5mm peel-away temple pads adds another level of customization, giving the helmet interior a little extra width when needed
  • Enhanced for customizable micro fitment interior without the need to purchase extra interior components
  • New FCS (Facial Contour Support) cheek pad design
  • Innovative and exclusive spring support adds just the right amount of pressure when needed while being worn
  • The Arai Signet-Q US Flag Helmet Meets or exceeds Snell and D.O.T. standards

Arai Signet-Q US Flag Helmet 4.8 5 301 301
arai Very comfortable, light weight, and comfortable. Pin locks works great. November 23, 2015
great helmet for long oval head shape This was my first Arai helmet ever and I am pleased with it. I took it on a 2500 mile trip this summer just after purchasing it and I would say that no break in period was even needed for me to see positive results. I have a long oval head shape, and other helmets have been miserable, putting too much pressure on various head pressure points. I can comfortably ride 100+ mile stretches without needing to constantly adjust the helmet to relieve pressure like on other helmets. If you have a long oval head, this is worth the investment. November 9, 2015
Nice, very nice. If you have a funny shaped head like me it it is difficult to find a nice helmet that fits well, doesn't press on your forehead, and that looks good. This helmet is all day comfortable and flows enough air to make the hottest days tolerable. September 14, 2015
Great helmet This is an awesome helmet. I've used a couple different brands and this one is by far the most comfortable to wear and has great noise reduction. It's very easy to adjust the airflow while wearing it and riding if necessary as well. October 26, 2015
Nice fit for long oval head I chose this helmet because it specifically was designed for long oval head shapes, which I have. I like the fit of it very much. My bike is in the shop right now, so I can't comment on the rideability aspects of the helmet yet. October 20, 2015
Good helmet, but not a Profile fit. I previously had an Arai Profile and this helmet is a nice upgrade as it's much more quiet and the sun shade is a nice feature. But, be warned, this might be a long oval, but it's not a replacement for a Profile as it fits much more snug than the Profile and has left me with hotspots in the back of the head after longer rides over 1.5 hours (with my profile I could ride all day long). If the fit was more like the Profile, I would have given it five stars. October 14, 2015
Excellant helmet! Was debating for a while to get this helmet as my previous one HJC 10 was fine. But am very glad I did! Use it for street and track. Fit is perfect for my head as I've only found a few that are truly comfortable. Overall quality is great, vision is great, airflow is great, nice attention to detail everywhere. Chin strap is comfortable too. If you're thinking about it, get it you won't be disappointed. Wish I got it sooner. October 9, 2015
There is a reason it has five stars By the time I need a new helmet this will have cost well less that $0.25/hour of use. I really wanted to like the Shoei GT Air, but it just didn't fit my head. I don't know why I bothered. FWIW, this is my third Signet. First was an e, then a GT, now a Q. Thank you Arai for bringing this back. I wore an RX7RR4 for a long time, but it was never as comfortable. September 30, 2015

RevZilla Store asked: Why did you choose this?
Carl F: Buy a $10 dollar helmet if you have a $10 head! At least you know how the phrase goes. Seriously, I normally opt for Shoei products but have always wanted to try an Arai. This helmet fits me perfect. I can tell a huge difference in the amount of air flow/ventilation. This helmet ROCKS! Oct 12, 2015
vaughn r: Protection and style Sep 22, 2015
David M: Always get ARAI top quality, and the design is killer...... Sep 3, 2015
David C: Arai quality first and foremost, cool design and Revzilla pricing. Jun 9, 2015
Stephen C: It was time to step up to a real helmet. Jun 1, 2015
David S: I chose the Arai Signet-Q helmet because I needed a long-oval fit. Arai's reputation for safety and top-notch quality influenced my choice to go with Arai, and the great looks of the Frost Black US Flag model sealed the deal. May 5, 2015
Anthony W: It's beautful ! And not as expensive as some of their helmets Mar 25, 2015
J I: Arai quality and great looks to go along with my new 2015 Silver Smoke Indian Scout. Nov 29, 2014
MAX V: I am a long time user of Arai and loved my previous helmet, an old Quantum F model. It's time to upgrade and with a US Flag on it, hell, that's a bonus. Arai is a great helmet that in my opinion can't be compared in fit, style or looks. . Aug 24, 2014
Jonathan C: Maximum protection and best fit for my type of head (oval). Very comfortatble and lots of air vents to keep me cool plus the new double paned screen thanks to pinlock. No more anti-fog chemicals is a major convience. May 21, 2014
James M: great reviews. beautiful helmet May 1, 2014
Thomas K: i have a bpg head and everyone said this is the best helmet Apr 20, 2014
Curtis C: 'Great Quality' helmet for racing karts and riding my motorcycle. I own another Arai helmet that is five years old and in perfect condition although the karting association I race in requires the Snell rating to be current. Mar 5, 2014
Mike H: Great quality, perfect find for my head size, full face protection Feb 28, 2014
Shane V: Great fitting helmet for my head shape, and best quality. Dec 16, 2013
A shopper asked: Is the helmet available without the Arai logo on the sides? Or can they be removed? Really like the helmet, just too many stickers! Sep 6, 2015
Answer this · Send to friends Good question? Yes (0) No (0)
Alfred O: Don't know. You'll have to ask Arai if they have one without. I took a close look at mine. Stickers are pretty thin and stuck hard to the surface. I don't think it's likely to come off easy without risking damage to the artwork underneath. I thought about taking them off when I first got the helmet. But got used to them after a while.

James F: Hi,

I asked the same question when I bought mine and was told no.
It doesn't appear that they can be removed as it looks like they are under whatever the coating is that produces the matt finish.

Patrick M: No the arai stickers can not be removed. Overall it looks better live than the pictures, and I am happy with how the helmet looks. It it would be better if the arai stickers were not there Sep 6, 2015

Dan S: On my helmet, the side logos appear to be silk screened(?) with the rest of the graphics, but the front logo is a thin vinyl applique that can probably be peeled- carefully. Sep 6, 2015
