Arai Signet-Q Zero 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 Zero Helmet 5 5 2 2
Quite an upgrade I had an 8 year old HJC modular and was a little leary of switching to full face. After talking to one of the riders at Revzilla I decided to give it a try. Glad I did. Noise way down, really comfortable and I love the colors. The extra space is an added bonus. Love this helmet so far and would recommend checking out ARAI if you're in the market. July 30, 2015

RevZilla Store asked: Why did you choose this?
J O: After talking to one of the riders at Revzilla I decided to go with the Signet because of the extra space since my previous helmets always seem to pinch my forehead after a short time. I also wanted a comfortable helmet and all the reviews pointed to this helmet. Looking forward to trying it out. Jul 10, 2015
Gregory W: After trying many different helmets, the Signet-Q was the best fit. My cranium is worth the price for good comfort and excellent protection. This model particularly for the colour and styling of the graphics. Jun 15, 2015
Justin P: Nothing fits me, right off the bat, better than an Arai long oval helmet. Jun 10, 2015
