Arai Signet-Q Racer Helmet

The Signet-Q takes all the favorite features of the RX-Q and create a whole new series based on all the successes. On the outside, the Arai Signet-Q Racer Helmet looks very similar to it's namesake, the RX-Q, but on the inside you can see and feel the difference. A longer shell shape on the Arai Signet-Q Racer 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 Racer 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.

Additional Features of the Arai Signet-Q Racer Helmet

  • 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
  • Arai Signet Q Racer graphic has the 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 helmet for a long oval head Fits like a glove! Has good airflow. Has all the things I liked about my previous ARAI helmet. New visor insert shield is a little cumbersome to get in and out. Sometimes the sunlight makes it in the spaces where the tinted visor doesn't cover. Would rather have a full tinted shield instead of the insert. LOVE the rear vent, easy to open and close!

Excellente protection for guys with long oval shape head It is the only option for guys with long oval shape head. Vision is somehow limited, but otherwise is an excelente helmet. August 18, 2014
Finally a helmet that fits comfortably and has airflow I never considered myself to have a more oval head shape but apparently I must because this helmet fits perfect. Other helmets now feel round to me. Helmet has great airflow with all the vents open. The brow vents move air as described to your tempels and ears, keeping your ears very cool. However with great venting comes wind noise. Ear plugs helps for highway speeds, city use not needed. Very stable at speed, no neck fatigue at high speed on highway. Completely satisfied with this helmet. July 31, 2014
Comfortable, quiet & scoops air. What could be better??? This is an expensive helmet. What do you get for those extra dollars? Build quality! This thing is a solid lid with nice hardware. Comfort! The liner is tunable and made of quality material. The visor is nice and wide and absolutely no defect or waviness in the face shield. Air-flow! This thing shoves air in your face and circulates it all around your noggin. There are other helmets that vent well but this lid does it at all speeds. I even get a breeze when stopped. When I first wore it I reached to pull the visor down when ridding down my neighborhood street at 10mph because I thought it was up due to the air-flow. Yes, it's that good. Quiet! Not stealth mode movie effect quiet but quieter than any of my previous helmets. You hear slight wind noise but it doesn't overpower other sounds as my other helmets did. Warranty! 5 years. Enough said. If you are in the helmet hunt this one should be at the top of your list. I've tried them on in store before and been tempted but have always gone with a cheaper helmet. I'm glad I didn't this time as I could tell within the first mile that this was a keeper!!! Previous helmets: Nolan, Bell, Bilt & Icon September 13, 2014
Good helmet. Not cheap but what's your life worth? If you have a long oval head like mine this helmet is great. For the first time I can wear a helmet and not have a headache and a huge red welt on my forehead when I take it off. The helmet is light with good air flow. September 2, 2014
The Arai Signet Q is a great Helmet It took a while but the guys at Revzilla got me fitted with a great helmet at a great price. The ventilation is great, keeps the visor clear at all times. Very comfortable and light - no turbulence at speed. I haven't been on a bike in 20 + years and I had alot of questions. They had patience with me and answered every question never talking down to me. This is my go to place for bike "stuff" - thanks guys. Signet Q American Flag Helmet September 1, 2014
Helmet fits well for XXL and tends to transmit excessive noise Great helmet! High quality in every aspect. Safety standards are well met. XXL fits tight for my 7 3/4" head size. Helmet could have better noise management. I theorize the extra tight fit promotes noise transmission from helmet wind buffet. Ear plugs are a must. For my head size and long oval shape, the Signet is the only helmet for me. I've had two. September 1, 2014
Finally a helmet that fits! Just received the Hi Viz Arai Signet Q helmet from RevZilla. Initial fit is tight, but after only a few rides it feels just right. The long oval shape is perfect for me, and Medium seems ideal (head size 57.5 cm). One thing I noticed on the very first ride with this helmet was that is actually has ventilation that works...I've owed a number of full-face helmets (Shoei, Bell, HJC) and none of them had ventilation that I could feel...this Arai actually cools my head with noticeable (and adjustable) flowing air...nice!! Also I noticed that this helmet has less buffeting in a strong cross-wind, probably due to an overall smaller shell for the same internal size. The hi viz color is very obnoxious and exactly what I wanted. Received this helmet within 48 hours of ordering ! thanks RevZilla team ! August 21, 2014

RevZilla Store asked: Why did you choose this?
Tim G: It was time to replace my old Arai helmet and I can't imagine using any other helmet but Arai. Jul 12, 2014
Miro C: Your helmet is a very important part of your ride. A good, safe, and enjoyable helmet transfers your ride into a better one. And Arai is the brand which knows how to make a really good helmet. The Signet-Q is a perfect choice if the shape of your head is a little longer. Allows some very useful fit customization, too.

Vance H: While I don't know exactly what riding position Arai intended for this helmet, I have been wearing it while riding a Harley-Davidson Road King, a H-D XR1200X Sportster, and a BMW R1200GS. All of these bikes have a fairly upright position, no kissing of the gas tank required.
For me, this has been the perfect helmet and I now own two of them. The venting has been very good and there is almost no buffeting on any of the bikes: the Road King has a windshield the size of a front door, the Sportster has none, and the GS has a small-ish one.
As this helmet is designed for narrow heads and has an increased front-to-back dimension, relative to any given head-size width, I was able to step down to a size "small" when I have always had to wear a size "medium" in all other helmets, such as a Shoei X-eleven.
I was a bit daunted by the prospect of changing the face shields, as the Arai helmets are known to be so hard to change that there are actually videos available showing how to do it, including on this Revzilla site. As it turns out, after watching the video and then practicing a few times, it really is pretty easy, not to mention quite fast as well. The shields seal around the eye port well and mine have never admitted any water on those times I've ridden in the rain.
I've heard complaints that the chin strap is way too short, but while mine doesn't have enough extra length to lasso a horse, it certainly has enough to allow for proper cinching. It is shorter than any of the Shoei helmets I've owned, though.
I'm now an Arai guy.

Kent B: Jamie,

The Signet Q is designed for the same riding position as Arai's RXQ helmet and that is the upright cruising and sport touring positions. I ride a Honda GoldWing and was going to purchase the RXQ but wanted a little more room around my chin. I am very happy with the Signet Q and can wear it while riding my other bike which is a BMW K1200 R Sport (sport touring riding position) with no ill effects.

Robert P: I use my Signet-Q for long distance touring on my Ducati Multistrada 1200 ST as well as for riding on my Ducati Diavel which is a fairly naked sport cruiser. It works well for both upright riding as well as leaned over the bars sport bike riding. I have done track days with it also. The pull down chin protector gives added wind protection when in an upright riding position. Nov 13, 2013

dennis e: I don't know the design but I am using it on a standard (upright) sport bike. If you have a long,long oval like I have this is the helmet. Tried many before I bit the bullet and purchased this expensive but fitting helmet. If you have ever had a hot spot you will understand. Nov 14, 2013

Robert S: I'm not certain of the riding position for which the Signet-Q was designed. However, I can tell you that the ventilation is incredible for the riding position associated with my BMW K1300S, which is moderately forward-leaning. Nov 13, 2013

A shopper asked: I have been wearing Shoei large size helmets for the last few years. The Multitec feels too big and the standard full face Large Shoei feels just right. What size Signet would fit? Large or Meduim? Feb 27, 2012

RogerWilco: I have a Shoei X-11 in a size Medium, which fits nicely, or so I thought. Because of the long oval shape of the Arai Signet Q, I was able to go down to a size Small. It fits snugly and seems to make full contact around my head, but it is very comfortable. More comfortable than the Shoei.
When my head was measured it was found to be just a little large for the Small and at the very bottom of the Medium range. I opted for the Small and feel I made the right choice: zero hot-spots, no headaches. I never realized the Shoei does indeed have a little bit of "flop around" when doing a shoulder-check, until I discovered that the Arai is rock solid. I believe this is because the sides of the Arai are in contact with my head, whereas with the Shoei in a size Small I got forehead hot-spots; with the size Medium there is extra space on the sides.
I just wish the helmet strap was a little longer. I would have gladly paid the extra nickel!

KeithK: I was wearing XL Shoei and had excessive forehead pressure. Sides had room, though. Based on Arai helmet sizing, my size was on upper end of Large, but not quite XL. I ordered Signet Q in Large. It felt snug but more comfortable than the Shoei. (The difference between long oval and round oval.) I am pleased with the Large size Signet, though I ended up removing the 5mm peel offs from temple and sides. I suggest going down a size IF your sizing is between one size and another. I measured my head per Arai instructions several times. Do not order until you have done this. Mar 6, 2012

Wilberforce: I have both brands, Arai Signet Q medium and a Shoei Qwest in the large size. The Arai fits me great the Shoei is too large. So If you like a Shoei large I would recommend the Arai large size in the Signet Q. Nov 12, 2012
