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

As good as it gets This is my 5th ARAI helmet...they don't make them any better and the oval shape is perfect for me. July 14, 2014
Great helmet, love it, but got stolen I only worn this helmet two weeks and it is stolen, I would recommend this helmet to everyone, even with a round shape head it is still very comfort and quiet. It keeps me cool with the vent and it is very light. It is such a pain to have such a great helmet stolen. June 28, 2014
great helmet but just needs to be lil more long oval love the helmet and the fit is absolutely perfect except for one area. i have a very long narrow head, the helmet fits great side to side. no hot spots on the forehead either. the only complaint is that the chin bar is to close to my chin. i actually touch the chin bar and breath curtain with my chin and nose, if i do not get the helmet on just perfect.Icould have went up a size to stop this but the large fit like it was made for me so i am living with this. you get used to it. This is my third arai and i have tried many others but nothing fits like it. I went and switched back to the normal shield i did not like the pin lock visor, hated seeing the edge of the pin lock. it did work great though. no fogging. June 17, 2014
Arai continues to earn its place as a top-level helmet manufacturer. In the tradeoff between noise level and ventilation (which seems to apply to all helmets, no matter how well-engineered they are), the Signet Q is exactly where I want to be. During prolonged trips at highway speeds, it does become a slightly-loud helmet, but the level of ventilation is exceptional. While the wind noise is nowhere near what I would call ridiculous or unbearable, a pair of earplugs will make a long journey much more comfortable. One obvious benefit of this is that in slower riding conditions, the unmuffled sound input helps to keep you aware of your surroundings, while the ventilation system continues to work flawlessly. For visibility, a wide shield offers just about all the peripheral vision a rider could possibly use, and the fit & finish of this helmet is second-to-none. For those with a long-oval head, this may be one of the best-fitting helmets you will find. July 14, 2014
Great helmet This is my second Arai Signet Q helmet. The extra-wide field of vision is very nice. The helmet flows enough air that you can feel it around your forehead and scalp at speed. At the same time, it is a relatively quiet helmet. Still, I wear earplugs when I ride regardless. Typical Arai quality on fit and finish. The adjustable cheek pieces add another level of customization. July 10, 2014
Great visibility & comfort This helmet replaced an Arai Profile also in large size. The Signet-Q fits a bit better than the Profile, but I did need to remove a layer from the cheek pads. It fits my very oblong noggin much better now: there was a pronounced hot spot on my forehead with the old Profile (which I dealt with using a large serving spoon to flatten the styrofoam a bit, which had to be every ride), but no hot spots at all with the Signet-Q. I'll update this after the long tour I plan on taking in August to the Rockies, but so far, I'm very happy. I only wish they could have had more stock of the Pro Shade system to supply their dealers. Also, I think the hi-viz has saved my butt a few times already. It seems car drivers actually see my hi-viz mellon coming from a good ways off. July 7, 2014
Very comfortable, and good fit.... Very comfortable, and good fit..., plus very quiet. I like it a lot. June 25, 2014
Best helmet I've had I upgraded from a 2010 Shoei RF-1100, and it is a large improvement. Much better ventilation, and so much quieter than the Shoei. The face shield seemed difficult to operate at first, but I've gotten used to it after only a couple of rides, so it's good. The top vents add noise when in the open position, but you can really feel the air blowing through, so that's a fair trade-off. The sales guy made removal of the face shield seem extremely complicated, but after reading the manual I got it within the minute. I suggest sales guy read the manual as well :) June 23, 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
