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

Arai Signet-Q Racer Helmet 4.8 5 230 230
The Right Fit After going to the New York IMS we got properly fitted and we got some recommendations from the Arai booth I ordered a signet. I was then able to get my helmet and get it broken in. Had to order the slimmer cheek pads to accommodate my face but what a great fit afterwards. It's mildly noisy on different bikes but not really too bad, air flow while moving and again on different bikes seems to be a big variable, but not by far a deal breaker. The protection is absolutely the best and after being hit on the highway by a tour bus and taken out all I can say is all my gear performed perfectly. Take the time to get the best you can afford, it CAN save you in a crash. On a secondary note one of the vents broke, called in and they sent me out the parts quickly and easily. It was a DIY job easy no need to send it back. Overall a great helmet with great features and a company that backs their product up. December 21, 2014
Amazing helmet. Perfect fit With an egg for a head I have been searching for years for the right helmet. This is the only one that fit just right. It's perfect for long oval shaped heads. Yes it is not the cheapest but you will not be disappointed in the craftsmanship of this helmet. I will not wear anything else and I've tried them all. December 15, 2014
Superb fit and quality Strapping this hemet on is a pleasure. It is so comfortable and fits my long oval head so well, sometimes I kind of forget I have it on. It is quiet and does not create any headache or hotspots at all. Since I was a kid I guess I always had a poorly fitted helmet or was using one that was too big. After spending time and researching this product line and trying a few on, I quickly found that nothing compared. The look, comfort and fit is so spot on for me I cannot say enough. Thanks for delivering in such a timely fashion and to the help I received over the phone for other "options" After I tried the Signet Q helmet on, there were NO other options.. October 28, 2014
The best costs money, but it really is the best! After the padding on my current Arai Quantum E that I bought in 1997 starting breaking down, I went on the search for a new helmet. Remembering the $700 I spent on the first one thinking that they'd last forever, I didn't want to spend as much this time. After seeing how much helmets have changed since I got my last one and seeing how reasonably priced some of them were, I thought for sure I could find one that fits perfect for maybe $200. I've got a large head and it's also a long oval shape. For this reason the helmets in the 90's didn't fit great and I had to get an XXL helmet so my head would fit in it front to back. At high speeds my helmet would push back against my face and I got some buffeting on the highway. I figured I could drop down to an XL and get the right head shape and it would fit much better. After finding that some other brands now have long oval helmets for reasonable prices I set out to find the perfect one. I tried the Icon Airmada and for some reason the neck roll has a grippy rubber on it that grips and pulls your hair as you try to get it on, and I couldn't even get my head in to an XL and I knew with the right head shape I shouldn't need an XXL. I tried helmets from AGV with a Rossi paint scheme and a Bell Vortex, Shoe RX1200 and the head shape was no where a perfect fit. Long story longer, I tried an Arai RX-Q knowing it was out of my price range but I figured what the heck, I'll see what they're like. It was the best helmet I tried so far. I could tell the padding was superior, the visor and strap was high quality and the paint was beautiful. I then found the Signet Q, the longest oval of the bunch and instantly it was like baby bear's bed, just right. I watched a video online about Arai's quality standards and I was sold. Less wind noise, less buffeting, higher safety standards than Snell or Dot, and it's comfortable. The removable interior lets me wash it unlike my last one with just removable cheek pads. The interior has come a long way. So I guess I'm an Arai guy still. Hopefully this one last a long time too. I figure the cost isn't so bad when you think that it's probably the most personal piece of ridding safety gear you can buy and I figure, if I'm going to spend that much on a helmet it's got to look good, and it does! I did change my mind on color and Revzilla swapped it out as easy as pie with no issues. If you've got a long oval head, and can handle the cost, just get it. Cheers and ride safe! October 20, 2014
Worth the investment for (freakishly) long oval head As a new rider I made the mistake of buying a HJC helment because it fit my budget and was comfortable in the store. Don't get me wrong, it is a fine helment at the $150 price point, just totally wrong for my long oval head. I started to get a headache after 20 minutes. Two hours into a ride and I wanted to DIE. I knew I was going to have to invest in a new lid. This time, I did my reasearch. After reading recommendations for long oval helments and trying them all on, I narrowed it down to the Icon Airmada and the Arai Signet-Q. I visited the store several times and could not decide. After talking at length to the Arai rep at a local show I decided to bite the bullit and shell out the $600 for the Arai. I am on a pretty tight buget, so this kind of investment was a reach for me. I am so glad that I did. I went on a 3 hour ride this weekend and the helment was completely comfortable right out of the box. I feel like I could wear it all day with no issues. Comfort was absolutely my only concern, so it was a total bonus that the helment also vents like a mofo and while there is always wind noise, it didn't whistle AT ALL even with all the vents open at 90 MPH. And I think the Hi-Vis yellow looks badass. I suppose it is possible that I could have saved $350 and been equally happy with the Airmada, but I have my doubts. I firmly believe that you get what you pay for with the Arai. I am pleased (and relieved) with my decision. November 10, 2014
ARAI has outdone themselves with this helmet! This is a remarkable helmet is every way. It's the RX-Q, which is a terrific street helmet, but designed to fit the longer oval head. And it's adjustable for comfort, by removing the 5MM peel-away cheek pads. The liners and pads are washable. The Pinlock faceshield with optional tinted visors is an added bonus. Anthony is right! This is one great helmet, from the world's leading helmet maker. This is my second Arai helmet from Revzilla. These fellows know what they're doing. They are all about customer service and satisfaction. From the informational videos on almost every product they sell, to the super prices and return policy, and the phenomenal after-care service, in case you have a question or concern. They are the best. I'm a huge fan of Revzilla, can you tell? (And no, I don't own part of the company. I'm just a very happy customer.) November 3, 2014
It's an Arai and the fit and quality are the best. Pros- The fit is exactly as advertised and extremely comfortable. There are no hot spots with this helmet. Cons- The wind noise is quite high with the shield down; something I didn't expect with this helmet. I ride with polarized sunglasses and the face shield puts the glare back for some reason. Finally, the fog shield doesn't seem to work for me so I removed it and ride without it; it didn't work well with glasses adding glare from headlights. October 27, 2014
Great Helmet! I tried a comparable shoei gt air and my old helmet was a non comparable icon alliance xxxl. My head is large Charlie Brown virtual planetoid, this helmet in 2xl fits great! Plenty of room for the ears. It fits great and doesn't put odd pressure anywhere. I usually ride with the visor open, but its very comfortable with it down or up. The vents work great and the weight is good, minor wind noise when checking left and right but overall I am very happy. Price was a bit more than I wanted to spend but you get what you pay for and after all said and done, it is your head your protecting! October 27, 2014

Derek C: Never realized I had an elongated head until I tried this helmet on. Finally no more pressing on my forehead! Great quality, great venting, plush liner, little loud but I wear ear plugs or headphones anyway. Dec 17, 2014
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!

Keith K: 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
