What's this?

Arai Signet-Q 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 spots
  • 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
  • FCS (Facial Contour Support) cheek pad design
  • Innovative and exclusive spring support adds just the right amount of pressure when needed while being worn
  • Snell M2015 and DOT

Arai Signet-Q Helmet - Solid 4.8 5 362 362
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
Exceptionally Comfortable! I purchased this helmet to replace an 8 year old Arai Profile. I ride almost every day so comfort is important. When searching for the replacement I was open to other brands, I just wanted a flat black helmet that would look good with a dark smoke visor. I had first purchased an AGV AX-8 Evo Naked for the looks. That helmet fit horribly and I ended up returning it within the hour I opened the box (thanks Revzilla!) and buying this Signet-Q Pro Tour; mostly because it has the long-oval shape that I needed. The Signet-Q provides a VERY comfortable fit. My first ride with it was about 8 hours and I had no issues with fit or comfort. My head circumference measures 58.5, so I went with a large and it fits nice and snug. With the helmet, I also purchased a dark smoke pinlock visor along with a regular SAI dark smoke face shield. The SAI face shield looks much better on the helmet. The only problem is that when removing the pinlock face shield, the Pro Shade comes off with it as it is attached to the face shield. The black frost helmet has the 'murdered-out' look to include minimal decals and all of the decals are black. I am very happy with the purchase and Revzilla had the best price that I could find. August 28, 2016
No Surprises from Arai Purchased this helmet for my wife. She has had several 'starter' level helmets but with the purchase of her new Ducati Scrambler it was time to move up to something of higher quality. The quality of components and their fit and finish is consistent with other Arai helmets that I have owned. She is very happy with the fit of the shell, how easy it is to clean the inside, and how quiet is is compared to her previous helmets. She also said she experiences less buffeting and the vents work great! July 13, 2016
Excellent design I purchased the Signet-Q 4 months ago and have worn it commuting and all day rides since then. It fits my oval head perfectly with no hot spots and ALL of the features of the helmet work exactly as designed. It is one of very few products that I've purchased that I am not at least a little disappointed with. I read that another reviewer had trouble with the tinted visor not staying up. After you raise the external, tinted visor you have to push it rearward and it locks into position. When you want to lower it you have to pull the tinted visor forward out of its detents then slide it down. The only time mine has come down was before I knew I had to snap it back into its detents. Ventilation is as described. It is easy to get a comfortable gentle breeze through the helmet when it is hot (I've ridden from 55 to 104 degrees.) and to close the vents and lower the chin guard while riding in cooler weather. Removal and reinstallation of the cheek pieces is a little tricky the first time, but easy to do if you repeat it a few times. (I watched an online video.) I've removed and washed all of the internals several times. If it fits your head, the Signet-Q is a first rate product. August 27, 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
