What's this?

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 5 360 360
I have finally found a helmet that fits I am already an Arai customer for life. This is a beautiful, high quality helmet. The details and small design features are great and tells me that this company actually cares if they make a great helmet. The airflow is amazing and is engineered into the helmet, unlike most helmets that just have a holes drilled into them. TRUST THE SIZE CHART. I was skeptical but I measured and ordered an XL and it fits perfectly. My last helmet is a Schuberth and it is a 3X, so I was expecting to return for a larger helmet. Aria knows what they're doing. I also have used modulars for 6 years and I have gone back to a solid helmet. No regrets. The modular is overrated for features and adds weight and expense. Love this helmet. August 16, 2016
Long Oval Heads Unite! I've tried on dozens and dozens of helmets. The Signet Q is the only one that fits my long oval head without pain. Unfortunately, it's darn expensive. Still, since I purchased this helmet I'm riding pain free for the first time in years because it actually fits my head. When helmet shopping, fit is my #1 criterion. My head is long from front to back and fairly narrow from side to side. By the time most helmets are long enough front-to-back, they're a size or two or three larger than what I need in width and rattle around because of all that extra side space. Bang for the Buck The bang for the buck is not good with the Signet Q. But it fits. If I could find another helmet that fit my head comfortably I would buy that presumably cheaper one instead. But I can't. Style I don't care about style. I do care about Hi-Viz. Comfort The Signet Q is the only helmet I've found with a long oval shape that will fit my head pain-free. If you have a long oval head, try the Signet Q. It's longer than every other helmet I've tried. Both of my brothers agree. Protection & Durability No idea about protection. Durability is adequate so far. There is a a soft fleece-like covering that surrounds the helmet strap on the left and the right side of the helmet. On one side, that soft covering has broken loose from its anchor (on the inner side of the helmet) leaving it to roam freely up and down the strap. Every few rides I stuff it back into place, but I cannot re-anchor it. I may eventually sew it in place. Air Flow Outstanding. My brother owns the same helmet. He wears his visor down all the time, even in extreme heat, because he feels the Signet Q flows air so well. I agree that with the visor down it flows significant air, especially across the top of the head. Features It's an Arai. There are no features. I wish there were. Fit Long oval. Longest I've found, with enough room for my ample forehead. Noise It's about average, I think. I wear earplugs when I ride so it's mostly irrelevant to me. But any helmet that flows significant air will be louder than those that don't. Weight I have no idea. Shape Have I mentioned it's a long oval fit? Vision Vision is excellent. It has a wide field of view compared to my other helmets. Interesting Story Went to a big motorcycle show. The Arai rep looked at my head, touched my head briefly with the thumb and forefinger of each hand, and told me the exact circumference of my head (I've measured it) and which Arai model would fit me comfortably. In an effort to save money I purchased three other helmets before I finally purchased the Signet Q. And the Arai rep was 100% correct. July 12, 2016
Wife is Happy...Great Customer Service!! My wife and I both ordered a Signet Q Pro, hers a medium that fit perfect, mine was an extra large and I couldnt close my mouth (fish lips)...just tooooo small....I measured myself again and found me to be a 2X Large....I called the next day and Brittany was awesome..apologized and sent me an email for the return...since it was my first they waived the return shipping of $7.95. I trie to order it in a 2XL but they didnt have the same Black to match the wife's Signet so I did some research and went with the Defiant Pro Cruise, that was on a Thursday and tracking says it will be here on Monday...GREAT Customer Service all round and look forward to purchasing more in the future...$1200.00 for two helemts and wife didnt blink an eye... 16 HD Ultra Limited August 21, 2016
SPecial size for narrow heads No one makes a helmet that fits someone with a long oval head like the Signet-Q from Arai. The fit and finish of this helmet is beyond any other manufacturer. I've had HJC, Bell, Nolan and nameless brands and none of them fit a long oval shaped head. Finally, excellent finish, great graphics and replaceable pads for when your sweat just permeates the originals and they have to be replaced. Different tinted wind screens and durable designed movable parts. Great helmet August 19, 2016
Worth Every Penny! I've owned several brands of helmets and this is the absolute best. The Signet-Q model is designed for riders with long-oval shaped heads and the comfort is outstanding. Very quiet, great airflow and wide field of vision. The brow vents in the face shield flow air right where you need it on hot days. Super lightweight and the Diamond white finish is awesome. Arai helmets may be a little expensive but you get what you pay for in terms of safety and features. August 16, 2016
Brilliant!! Made for long oval heads....which no other brand can match. Airflow you can really feel, and on cool mornings you can shut off easily. Not quiet, but with earplugs it is perfect. Comfort? Oh yeah....wear it all day with no issues at all!! Knowing it will protect your brain....PRICELESS!!! August 7, 2016
Very good helmet I have purchased it 3 months ago and its great. Its air flow keeps me breathing at high speed and the comfort is amazing. I recomend for small faces and short chin faces. July 27, 2016
Excellent Helmet Been wearing Arai Long Oval helmets for years. Signet Q is the best by far. Like that it comes with a Pinlock lens. Wore a large in my previous Arai Profile but the salesperson in the Revzilla showroom recommended a Medium in the Signet Q. She was right. Snug, but oh so comfortable. Best part is they flat out work as designed. Recently crested a rise at about 45 mph and found an 8-inch deep pothole on the other side. Broke a link in the rear suspension and locked up the rear wheel. Skidded for about 40 feet and then fell. Hit my head twice on the road (yellow paint from the center line on the helmet). No headache, no concussion, no nothing. I've always been an ATGATT guy and all of it did its job very well. Bruised but no rash. Bottom line. Love my Arai. July 18, 2016
