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

Arai Signet-Q Hi-Viz Neon 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
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
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

RevZilla Store asked: Why did you choose this?
George R: Arai reputation, safety of Hi-Viz Yellow color, close to retro look of helmet for use on my Triumph Bonneville T100 retro bike. Oct 15, 2015
Elizabeth H: Model: because I have a long-oblong head & Arai is a great brand.
Color: so I am more likely to be seen rather than hit while riding.
Sep 9, 2015
Jeff L: This is the only helmet I could find that would fit the long oval shape of my head properly. The high visibility color is a nice feature and the visor is pinlock ready. Aug 4, 2015
John B: It sounds like a good choice for my long oval head shape. Good ventilation for summer and winter (fog free). Hi viz for safety. Aug 3, 2015
Ernest L: 1. Arai quality
2. Signet Q fit
3. Pinlock visor system
4. High Vis color

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
