Arai Signet-Q US Flag Helmet Videos

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 5 295 295
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
There is a difference The Arai Signet-Q is a huge step up for me. I had been wearing the HJC FG-17 because it was Snell approved, but it was very uncomfortable for my head shape - I'm long oval. The Arai does not cause pressure points. The air flow is spectacular compared to what I had before. Cooler than you would think for a dark color helmet. Removing and replacing the face shield can be a little tricky at first. The Arai runs large - I'm XXL in HJC, only XL in Arai and it seems roomy but not too loose. I tried a couple on at a local shop before purchasing with Revzilla - saved a bunch! As far as noise, you're always going to have some wind noise. It does seem like I can hear things a little more clearly with the Arai though. I am very happy with my purchase. I would give it 4.5 stars. Only regret is that I didn't purchase sooner. Thanks Revzilla! September 2, 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
Overall great helmet. Perfect fit, comfortable and not heavy on head. Needed a special size and found this was the best and fits all my needs. Very satisfied and Revzilla staff extremely helpful and knowledgeable. September 28, 2015
Love this helmet I love this helmet. I curtly own 6 helmets. This is the only one I can say I'm truly in love with. Fit is perfect. Style is perfect. Very light weight for a full face helmet. Seems as if I have way move vision wearing this helmet than I do from any of my other helmets. The only fault I have with this helmet is the tiny cheep lock pins on face shield. I watched the video on how to install face shield twice before trying to install face shield. First time I tryed it lock pin broke off. Had to by a new outer face shield. Way to expensive of face shield for a cheep little lock pin to break as easy as it did. And you can't buy replacement lock pins. Even after that happin I would still give this helmet a 10 out of 10 rating. September 28, 2015
Many features. Excellent helmet for long oval heads. Great fit, well balanced. Very comfortable. Good ventilation. September 28, 2015
Very solid and no nonsense build I've been using the same Arai Profile for about 5 years. And it's still going strong. Here are the strong and weak points roughly ranked in importance. + Build quality is very solid. Nothing has failed, loosened or fallen off in 5 years. No nasty surprises that waste my valuable time waiting for this or that. + Good aerodynamics with only a small amount in the early years. Turning of the head is getting noticeable now that the cheek pads have worn and its a touch looser. + No loosening or wearing down of the visor mechanism and stops; stays fixed in all positions to this day. + No annoying humm, buzz or vibe from some loose vent or screw. + Noise level is tolerable. Never been clamoring for ear plugs. Not as quiet as the modular BMW Motorrad (Schuberth?) that broke so much wind it had to go. + Input venting is good for the hot days and the temple temperature is noticeably cooler when the vents are cracked open. + The d-rings closures are solid, simple and work albeit a bit slower to manipulate. + Finish paint is durable; retains a newish look after years. And a few on in the minus department that can be fixed and some have been. - Not the best exhaust ventilation. Fogs at the hint of cold weather at slower speeds, and fogs completely over at traffic lights. Really needs its multi-stop visor. (Note Im referring to a 5/6 -year old model that had no pinlock) - The visor lock is difficult to impossible to use. The visor gasket is too thick for the tiny tolerance given to the mechanism. - A bit costly for a basic lid with no advanced composites (weaves, aramids), sun visor or sxy graphics. And some annoyances that have their +- trade-offs - Tactile switch for the top front ventilations is not a single decisive operation. Difficult to determine whether they're on / off by glove without toggling it two three four times. Rocker needs to be a touch longer -- but mechanism won't break easily. In contrast, the HJC CL-17 easy-to-determine position slider switch simply falls off its track when pushed with minor force which is easy-to-do with gloves; then you have a permanently open and very big vent. - The top visor vents are difficult to open with gloves. Again, its not a single gesture -- but at least they haven't broken off. Overall, I would recommend for someone unwilling to take a risk on the core basics and build quality. September 24, 2015
At last...a helmet that fit as it should! As a proud owner of a long oval (huge) head (melon) I didn't think I would ever find a comfortable helmet...but I did. For anyone who is similarly blessed call Revzilla and get the Signet Q. At first I tried Arai's Vector 2 and after sitting in the living room with it on for about an hour I realized it wasn't going to work. The customer service at Revzilla took care of me and exchanged it for the Signet Q. I couldn't be happier with the helmet AND the fantastic customer service. September 22, 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

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
