Arai Signet-Q Basilisk 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 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 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

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
Fits like a glove Having own 7 different Arai helmets, I knew I preferred the quality and fit of Arai. Tried the Shoei GT-Air, and the new Schubeth but for me... the fit isn't as good and comfortable as the Arai Long Oval. As in my last Arai, I needed to change out the cheek pads to get that snug but comfortable fit. Living in the Los Angles Area (traffic) I choose the Hi-Viz paint. I really does pop in traffic. Revzilla shipped incredibly quick. Ordered on Sunday and I arrived in California on Tuesday. Since I use Arai's, I knew the size and cheek pads needed. Great helmet and a great place to purchase. FYI ... I purchased helmets from other sites. The helmet manufacturer date could be a year or more old. I purchased this helmet in August 2014. The helmet manufacture date was June 2014. "Freshest" helmet I have ever purchased. August 17, 2014
Typical Excellent Arai quality. I commute every day, do track days, etc. and this helmet fits the bill for all. The Pinlock feature is outstanding for anti fog and I'm looking fwd to wearing it when the weather gets cold. The design is quite handsome and cleans up easily with water and a micro fiber towel. It's not a cheap helmet, but I don't have a cheap head. I highly recommend this helmet. August 16, 2014
Simply the best helmet available Just received my new Arai Signet-Q, just 25 hours after I placed my order, with free shipping! Amazing service from Revzilla! This is my 3rd Arai helmet, and they just keep getting better. Pick up an Arai helmet next time you're in a store, and you can see and feel the quality. It is so light weight, and the interior is plush. If you think Arai is expensive, break it down like this. Arai guarantees their helmets for 5 years, I keep mine for 6 or 7, so it comes out to a little over $100 per year. Now how much are you paying a year for your smartphone, or TV service, or Internet service, etc,etc. Doesn't seem so expensive now does it?? August 15, 2014
Beautiful fit and finish, but a little tight. I chose Arai based on it's reputation and on the recommendation by two shops that this helmet in a size small is what I should buy. It is a light and beautifully finished helmet. My only issues are that it causes a headache after 30 minutes of riding and the visor is finicky when trying to latch it closed. I can't blame the helmet for the fit issue. I guess this is why they recommended that you wear a helmet in the shop for a while to see how it feels after time. On the bright side, Arai Support gave me some options to try (pad modifications). For now I'm hoping the helmet will break in a little more. If you're looking for a safe, beautiful work of art, this helmet is for you! August 12, 2014
Very happy This is my 2nd Arai, the first was a 1st gen Quantum which I ignorantly wore in a L. I appreciate Revzilla's great review and sizing videos and customer service. My noggin measured between sizes at 58.5 so I called Revzilla and received excellent advice to step down to a medium. The cheeks pads were definitely tight at first (I left the 5mm inserts in for now), but after a week of use they are starting to break in nicely. The helmet itself it status quo Arai...excellent finish and protection, fairly pricey, and without some of the marketing bells and whistles of lesser helmets. I bought the hi-viz and it practically burns your retinas to look at it...which is perfect for commuting. I like that the helmet has space around the temples/ears for glasses. Definitely wear earplugs if on the highway for long distances, but I find I wear around town without them and it's very tolerable. As others have mentioned, the cheek pads have a somewhat rough texture, but I don't notice once it's on. It's also impressively lightweight. I'm very happy overall. August 11, 2014
Went straight to this as my first helmet for my first bike, not one regret After having tried on every Shoei in the store, I realized that Arai has a more oval shape than round, which was perfect for my head. I do not have a single pressure point on this helmet. My only two complaints are: The vents close themselves while riding from the wind, and the inside of the helmet is not very accommodating for Bluetooth speakers. I did still get some installed in mine, and they work great now, but it was difficult to do, so make sure you have some time to do it right. Overall, best helmet on the market, for my head. Also, extremely attractive design. August 7, 2014
Awesome bucket I was looking for a full face that had good airflow... We'll I will tell you I found it. You can feel the air from every vent on this helmet. It fits perfect based on arai measurement taking advice. It is super light and cuts through the wind with minimum head shake in an upright position with no windshield at high speeds. I have a Sena Bluetooth unit and have zero issues with noise from a phone and music perspective. Buy it.... August 5, 2014
