Arai Signet-Q Bomb 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 Bomb Helmet 4.8 5 319 319
Perfect fit for my head. Great valve. I have a long narrow head. I had an XL Shoei for 12 years that was great but to fit the length of my head it had a lot of space on both sides of my head and would move while riding. The Arai Signet Q fits my head perfectly in a Large. Lots of air flow with all the vents, especially the eye brow vents. Fits snug all the way around with NO movement. As with all helmets you need a tinted visor for riding on sunny days, which I just ordered. The pinlock insert is pretty neat too. It keeps visor from fogging when stopped at a red light. They also sent an extra yellow tinted pinlock insert with the helmet. The helmet is a bit loud, which doesn't bother me. Shipping was quick and helmet was delivered in mint condition. With the close out price you can't beat the value. Great job RevZilla! April 19, 2016
awesome product 100% quality. This helmet is awsome very comfortable and great fit. April 19, 2016
Excellent helmet Excellent helmet overall, the paint, fit and finish are all top notch. I've been wearing neutral oval helmets my whole life which left me with two options: snug fit with hotspots and a guaranteed headache or, a helmet that was unsafe due to being loose. I never perceived my head to be a "long oval" until I tried the signet-q on a whim. The helmet fits perfect and,although a bit tight at first, after 5 or 6 hrs of riding it's broken in and extremely comfortable. My only minor gripe is that the d ring strap is really short and can be a bit of a struggle to use with gloves on. April 19, 2016
Only helmet for long-oval heads If you have a long oval shape head, there is no other helmet on the market that even comes close - I had a Signet GTR for 11 years and this Signet Q is even better - light, quiet, excellent airflow, very comfortable, multiple sizes of cheek pads available - price was comparable to other websites but revzilla gave me $30 - some may say that Arai is too expensive, I say my brain is worth more than a muffler April 12, 2016
Top quality lid with exceptional features Basically I think this is one of the best helmets I have ever owned. To get the right head shape with the extra 5mm front to back is a dream come true. The features are second to none, including the ear cutouts for a comms system, the ventilation is unbelievable and the drop down visor is also excellent. I wear Transition Lens glasses which mean I get the best of both worlds without having to stop to change visors. I highly recommend this helmet and Revzillas customer service is second to none. Astonished that it arrived in a double packed box to Australia from the USA in 3 days. 3 days! Outstanding! I have written a more detailed review on my first impressions on my own website if this is allowed, read more here: http://dailybikers.com/arai-signet-q-pro-tour/ April 12, 2016
Fits my long oval head shape I bought this only because it was on clearance. I've never spent over $200. for a helmet in my 30+ years of riding. Other helmets start to hurt after an hour or so. Thought I'd see if the Signet-Q would help my egg shaped noggin. It has! I went on a weekend trip after only wearing it for a quick day trip. Road 450 miles the first day and over 650 miles the second and never had a pain from the helmet. I'm sold on the Arai long oval shape helmets from now on... The helmet is quite and has better features that I'm used to...you get what you pay for... April 12, 2016
Great helmet at a great price. Thanks REVZILLA for the great deal and quick service. I was worried about the oval shape but it is more of a round oval not a rectangular oval. Just need to get my headphones install and I'm ready to roll. Keep the rubber side down. Later April 12, 2016
Excellent helmet! Like a lot of people, I was hesitant to spend this kind of money on a helmet. However, I wanted a good helmet and I wanted it to fit properly. Trying helmets on in stores was frustrating because nothing fit correctly. This helmet came the closest and I decided to try it and see if it would fit after removing the 5mm pad from the cheeks. I will now that I am so glad I spent the $600! This is absolutely the most comfortable and the quietest helmet that I have ever worn. Hands down worth every penny that I spent. It is so quiet that I feel like my Sena 20 got a speaker upgrade. The music is so much clearer without wind noise. It is very comfortable, very good looking and I feel like my head is protected by a top quality helmet. The visor system is cool. I did order the longer pro shield visor. I am also going to add the light smoke pinlock insert. The drop down visor is dark, but I still wear it with sunglasses. They warn against this, but that's the lawyers talking. The shield is not so dark that you won't want sunglasses on also.I do wish that the replacement light smoke face shield accepted the drop down visor system. I want the light smoke as the regular shield and want to drop the dark visor over it. However I will just have to settle for the smoke pinlock and learn to live with the clear edges of the shield. That is just not as smooth of a look as I would like, but I understand them not wanting to get sued over doubling up the tints. So if the shape fits don't hesitate to spend the money. Your noggin' and your ears will thank you. April 1, 2016
