Arai Signet-Q Hi-Viz Neon 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
  • Meets or exceeds Snell and D.O.T. standards

Great lid *if* you're an extreme long oval I tried to love this helmet; for the price, it's not easy to walk away from. I have a long oval head according to everyone who's seen it (and since I shave, it's pretty easy to tell). Regardless, the Signet Q clamps my temples and barely touches my forehead and occiput, no matter how I try to modify the padding. Guess you need to be descended from those crest-headed dinosaurs in order to fit this model. If it does fit you, you won't be disappointed. Great airflow, nice padding (although it doesn't feel as plush as the Defiant; there's a very slight roughness to it), easy controls and, of course, world-beating Arai build quality. Just be wary and try it on without the neckroll and cheekpads before committing. May 19, 2015
Arai changed their sizing Been wearing Arai helmets for 20+ years but unbeknownst to me, they have changed their sizing and I confirmed with a local Arai reseller who experienced the same thing - he used to wear a M and now needs a SM. I have worn out my Profile and naturally gravitated to the Signet, its successor. My Profile is an XS but a Signet XS is too big and I need an XXS. The Signet doesn't come in an XXS so I will have to resort to another model. Thank you Revzilla for bringing in XS's in your lineup. Unfortunately, it's still too big for me. May 14, 2015
Changed Riding Having owned several types of helmets (and having test fit dozens) this is the first that has not created headaches. This is despite the fact I have always worn XL helmets, as recommend by manufacturer measurements. I fit in the middle of the Arai measurements for an XL, and took the chance on Revzilla due to the return policy. I stretched my budget for the Arai simply out of desperation to find a helmet to fit my long oval head. Other helmets I owned created severe headaches in 20-40 minutes of riding. I took the Arai on a 2 hour trip and was completely comfortable, with ZERO forehead redness. Compared to the 100-200$ lids I have owned, the quality is impressive, particularly the paint quality. Less noise, less buffeting, and greater ventilation was immediately apparent on the first ride. Visibility is perfect, and much appreciated is the anti-fog insert included in the box. The Florida coast is almost always high in humidity, and my old visors would often fog when closed. When in motion the Arai visor will not fog. In summary, this helmet ended the pain and made riding and a more pleasant experience. May 11, 2015
Amazing Helmet with Small Issues Bought this in diamond white to replace the rf-1100 that I crashed in. Love the look of the diamond white, it really pops, and the overall look of the helmet has really grown on me. It is definitely lighter than my old shoei and the vents are much more functional. I like that they put scoops over the holes so they actually catch air and direct it into the helmet. It also fits a lot better which I guess goes to show I should have gotten an arai a long time ago. If you're looking at shoei vs arai, note that among many differences is the fact that they are made to fit different head shapes. I highly recommend going to try some on before purchasing. The visor really had me frustrated at first because its not as easy to remove as the shoei was but after watching the video on how to remove and install it, and with a lot of practice, I've gotten the hang of it. I do like the way it detents into the open position and it seems to be a more solid design than the shoei, although I'm not sure I like that the mechanism is hidden. The pinlock insert is great because it will not fog but it also makes everything look a bit funny when it catches the light. I was excited about it but ended up not using it for that reason. The liner is more comfortable but the cheekpads are a pain to take in and out. I also haven't quite figured out how to install my sena smh10r without causing the cheekpads to be pushed further into my face making it pretty uncomfortable. There isn't an earhole like in the shoei and with the speaker between the shell and cheekpad the pads are pushed out, eliminating the little space where my glasses usually sit so nicely. The chin strap has no padding on the part that goes under your chin and gets uncomfortable after awhile. Overall I'm really happy with this helmet. The lighter weight really makes a huge difference over the course of a long ride and the vents flow a good amount of air. Put some padding on the chin strap and add an ear cutout in the cheekpad and you've got a no contest over shoei. May 6, 2015
Great helmet for a long narrow head! This is the first helmet that actually feels good on my head. I have a long narrow head shape. My head measures 23 1/2 inches and the large fits perfect. You have to break it in; it will feel tight for a day or two. Once it breaks in, it is great. Very little wind noise at highway speeds. The vents work much better than I expected and the Pinlock visor is amazing. Now if I could just get my eye glasses not to fog up when I get off the bike. Another note for people that wear eye glasses. My glasses fit fine with this helmet. Obviously I take them off until I get the helmet in place, but then they can be slide in place with no problems.

Most comfortable helmet I have ever had, Aria helmets have a excellent reputation and deserve it. The design is excellent and I installed a Sena 20s in this helmet very easily. I have purchased 2 helmets from Revzilla in Philadelphia and both times the salesman named Bobby was very good at sizing and advising me as to which model to buy. I buy some things online at revzilla but prefer to get a helmet in the store. I am very satisfied with this helmet. Steve Overstreet May 4, 2015
Wonderful helmet The Arai Signet-Q is so far advanced of the old Shoei RF-200 that it replaces, difficult to say anything bad about the Signet-Q. Helmet fits great, great, great!! Light, quiet, and wonderful vision. Only thing I miss is ability to lock the faceshield in a raised position for more fresh air. Facshield will lift but does not lock like my old RF-200. But there is so much better air flow that I am finding that I really do not need to lift the faceshield at stops like I used to. DId I say this fit is GREAT!! April 20, 2015
Everything I expected. I have been trying for years to find a comfortable helmet. this is my fourth attempt and I got it right. I took Revzilla's suggestion to give it the appropriate break in time and it made all the difference in the word. Wore it yesterday for a 5 hour ride and it is by far the most comfortable helmet I've ever owned. No pressure points, no fatigue, and light on my head. I winced at the price but considering 3 other helmets are in the trash mainly for fitment issues, this is money well spent. Highly recommended. April 13, 2015

RevZilla Store asked: Why did you choose this?
David P: Chose this helmet for the fit to my long oval head and because of its reputation. Mar 12, 2015
Kurt S: Fit and quality. The only helmet I found that fit my long oval head properly. Dec 23, 2014
Jeffrey M: Great fit, hi viz color. Dec 1, 2014
Erich P: I chose this helmet in order to get a proper fit for my long-oval head. After years of suffering with helmets that give me a pressure point on the forehead (due to being to short front-to-back), this helmet actually fits ! I also chose this for the hi-viz color which really is more visible at a greater distance (and more eye-catching close up) than other colors. Sep 7, 2014
Neil H: Its the only quality choice I could find for a long oval head shape. Aug 30, 2014
Bob C: I have always used Arai helmets. 7th Arai I purchased. (Signets, Vectors, XD's) The Signet Q is the most comfortable, high quality helmet I have worn. Shoei's, Bell's, Schuberts, and others just do not fit me as well as Arai. Apparently I have the "Long Oval American Head". Living in Los Angeles, I decided to purchase the Hi-Viz paint. Revzilla shipped quick. I will always buy Arai. Aug 17, 2014
Ryan F: It was time to replace my AGV helmet. I have a long-oval head shape and I found out that Arai makes a long-oval helmet, the Signet-Q. While it seemed a little pricey initially, it is well worth the craftsmanship and fit. It honestly feels like a custom made helmet. Arai has a lifelong fan and buyer in me. Aug 14, 2014
Meredith B: I have dread locks and I was looking for a comfortable high end helmet to protect the ol' noggin and found an Arai XL in a store to try on and it almost fit. I could tell that the next size up would be perfect. Plus, I love neon. Aug 12, 2014
Jordan D: I have a long oval head. All other helmets I've tried have been too short. Jul 22, 2014
Todd V: I have an extremely long head shape front-to-back and narrow side-to-side. I've been wearing an XL Arai Signet GTR that is very comfortable. Yet according to the chart (my head measures 23.25"), I should wear a large. I need a new helmet, so I am buying the Hi-Viz Neon (as opposed to the Diamond Blue which is gorgeous) to go with a Hi Viz jacket for increased visibility. I commute 85 miles (round trip) daily through Phoenix traffic to work. Jul 20, 2014
earl m: fits my odd shaped grape Jun 19, 2014
David W: Past experiences with Arai helmets. May 20, 2014
Richard F: I have a Profile that fits my head but is a little loose, so giving that to my big headed son and ordering a medium this time. Apr 18, 2014
John O: Quality, safety, fit. Apr 8, 2014
David D: Wanted a helmet that was great on safety and fit me well. Tried one of the arai signet-q's on at a local shop and it fit perfect, unfortunately they work off commission and had jacked the helmet price way over MSRP which bummed me out....but then i found it on here for a awesome deal, a safe helmet that fits my head shape perfectly is worth this price! Apr 7, 2014
Marv B: quality, fit, visibility Dec 15, 2013
William K: High visibility for safety. This helmet fits my head shape perfectly. Killer features. Oct 22, 2013
Craig B: Safety, esp Visibility, also I'm hoping the fit will be correct, I had a Qwest helmet that was too short front to back.
I'm at the upper end of the size range,
Sep 18, 2013
Joel H: I was looking for a helmet that has good airflow for Arizona. I've tried on helmets where my chin was lower than the chin guard which defeats the purpose of a full face helmet. Aria seems to be the only manufacturer that makes a helmet specifically to fit my shape. Aug 31, 2013
Theodore J: My wife made me do it. But at least I get to ride.... Aug 9, 2013
