Arai Signet-Q Flash Helmet Videos

Arai Signet-Q Flash 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.

Additional Features of the Arai Signet-Q 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
  • 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 Flash Helmet 4.8 5 218 218
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
Top of the line, but... The Arai Signet-Q is the best of the best for the long oval head crowd, as long as your long oval head doesn't have too tall a crown as well. I found the interior shape was perfect for my very pronounced long oval head, but the Signet-Q felt like it was sitting on my head. it just didn't have enough depth in the crown to come down on my head and settle; and my chin was wagging under the chin bar, even with the helmet tilted forward as much as possible. I got an Icon Airmada instead, problem solved; same large size, nearly the same long oval shape, almost as nicely made... returned the Arai, easy returns, thanks Revzilla! September 15, 2014
Comfortable, quiet & scoops air. What could be better??? This is an expensive helmet. What do you get for those extra dollars? Build quality! This thing is a solid lid with nice hardware. Comfort! The liner is tunable and made of quality material. The visor is nice and wide and absolutely no defect or waviness in the face shield. Air-flow! This thing shoves air in your face and circulates it all around your noggin. There are other helmets that vent well but this lid does it at all speeds. I even get a breeze when stopped. When I first wore it I reached to pull the visor down when ridding down my neighborhood street at 10mph because I thought it was up due to the air-flow. Yes, it's that good. Quiet! Not stealth mode movie effect quiet but quieter than any of my previous helmets. You hear slight wind noise but it doesn't overpower other sounds as my other helmets did. Warranty! 5 years. Enough said. If you are in the helmet hunt this one should be at the top of your list. I've tried them on in store before and been tempted but have always gone with a cheaper helmet. I'm glad I didn't this time as I could tell within the first mile that this was a keeper!!! Previous helmets: Nolan, Bell, Bilt & Icon September 13, 2014
Good helmet. Not cheap but what's your life worth? If you have a long oval head like mine this helmet is great. For the first time I can wear a helmet and not have a headache and a huge red welt on my forehead when I take it off. The helmet is light with good air flow. September 2, 2014
The Arai Signet Q is a great Helmet It took a while but the guys at Revzilla got me fitted with a great helmet at a great price. The ventilation is great, keeps the visor clear at all times. Very comfortable and light - no turbulence at speed. I haven't been on a bike in 20 + years and I had alot of questions. They had patience with me and answered every question never talking down to me. This is my go to place for bike "stuff" - thanks guys. Signet Q American Flag Helmet September 1, 2014
Great helmet for a long oval head Fits like a glove! Has good airflow. Has all the things I liked about my previous ARAI helmet. New visor insert shield is a little cumbersome to get in and out. Sometimes the sunlight makes it in the spaces where the tinted visor doesn't cover. Would rather have a full tinted shield instead of the insert. LOVE the rear vent, easy to open and close! September 1, 2014
Helmet fits well for XXL and tends to transmit excessive noise Great helmet! High quality in every aspect. Safety standards are well met. XXL fits tight for my 7 3/4" head size. Helmet could have better noise management. I theorize the extra tight fit promotes noise transmission from helmet wind buffet. Ear plugs are a must. For my head size and long oval shape, the Signet is the only helmet for me. I've had two. September 1, 2014
Finally a helmet that fits! Just received the Hi Viz Arai Signet Q helmet from RevZilla. Initial fit is tight, but after only a few rides it feels just right. The long oval shape is perfect for me, and Medium seems ideal (head size 57.5 cm). One thing I noticed on the very first ride with this helmet was that is actually has ventilation that works...I've owed a number of full-face helmets (Shoei, Bell, HJC) and none of them had ventilation that I could feel...this Arai actually cools my head with noticeable (and adjustable) flowing air...nice!! Also I noticed that this helmet has less buffeting in a strong cross-wind, probably due to an overall smaller shell for the same internal size. The hi viz color is very obnoxious and exactly what I wanted. Received this helmet within 48 hours of ordering ! thanks RevZilla team ! August 21, 2014

Alton W: Originally picked up the Signet-Q, and found it a little big. Picked up both the RX-Q and Signet-Q (smaller size) and determined the Signet-Q one sized down from what I normally wear fit perfectly. Just wish they offered more options in BLUE color schemes. May 2, 2014
Robert D: Time to retire my old one. I've had 2 Signet GTs, and they were great. I've tried Shoei and AGV, neither of which worked well for me. Sep 13, 2013
