Arai Signet-Q Basilisk 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

Wonderful helmet The Arai Signet-Q is so far advanced of the old Shoei RF-200 that it replaces, difficult to say anything bad about the Signet-Q. Helmet fits great, great, great!! Light, quiet, and wonderful vision. Only thing I miss is ability to lock the faceshield in a raised position for more fresh air. Facshield will lift but does not lock like my old RF-200. But there is so much better air flow that I am finding that I really do not need to lift the faceshield at stops like I used to. DId I say this fit is GREAT!! April 20, 2015
Everything I expected. I have been trying for years to find a comfortable helmet. this is my fourth attempt and I got it right. I took Revzilla's suggestion to give it the appropriate break in time and it made all the difference in the word. Wore it yesterday for a 5 hour ride and it is by far the most comfortable helmet I've ever owned. No pressure points, no fatigue, and light on my head. I winced at the price but considering 3 other helmets are in the trash mainly for fitment issues, this is money well spent. Highly recommended. April 13, 2015
No going back being a college student, an Arai helmet has always been out of my reach, but when I found a display model at my local dealer for %50 off, I couldn't afford not to get it. I came from an Icon alliance helmet that was affordable for me when i first started riding and offered a long oval shape that didn't hurt my head. being a long oval head guy, helmets are picky when it comes to finding one that fits right and even the icon left me wanting more. after wearing the Signet i realize that the padding in the top of the helmet makes a high difference in comfort. the icon lacked this and the helmet seemed to move out of a comfortable position as I rode. the Arai with its great padding sits exacty how it is supposed to when when you pull it on and stays there for the entire ride. it actually vents air too! the chin vent helps clear the shield really well and the brow vents are awesome, it makes a huge difference when its warm out. And when it is cold, closing the vents makes for a very quiet ride. I am super happy with it, and so long as i can afford them, there is no going back from Arai now. April 1, 2015
Worth it! It was finally time to replace my old (and very pink & girlie) helmet and after trying on numerous ones in the showroom, Signet-Q won me over. The fit is perfect, the weight is super light, the pin-lock is wonderful and my eyeglasses fit in with no problem. While this is a unisex helmet, the sparkles in the Diamond Black make it feel more feminine to me. March 27, 2015
Excellent Fit Best fitting helmet I have ever used. I have an extra long oval head. Try to find a helmet that fits that size head. I've tried many helmets, over the years, and right out of the box this helmet FITS with no hot spots. March 16, 2015
Comfort, but overbuilt.... For long oval heads, this is a very comfortable helmet, extremely comfortable. However, the vents, pinlock and open/close/tilt features are too overbuilt and quite counterintuitive. I've had to develop a muscle memory flick to get the thing open. Once closed if you don't open the shield outward at a 45 degree and up, you're beat. It will not open...apply that technique? Good to go. The salesman assured me that the pinlock woudn't fog. I laughed inside---it fogged the moment I closed it. Previous helmets with a 1/4 open feature stayed clearer. ALL THAT SAID, this is a comfortable helmet--it's going to break in fine. But, I've had to apply some serious TTPs (techniques, tactics and procedures) to live with it. March 10, 2015
Excellent Helmet I have a "long oval" head shape and this fits perfectly. The Hi-Vis Yellow stands out in traffic and the flat black accents make it look a little less dorky. The mechanisms, visor and pin lock anti-fog system are clearly high quality and very easy to use. I have had cheaper helmets and finally stepped up to an Arai. Overall there are three things that could make this helmet better. 1. Increasing the length of the padding on the chin strap. The strap itself rubs against your chin if you tighten it correctly. 2. It would be nice if they could figure out some way to reduce the noise inside the helmet. This is the quietest helmet that I have worn but quieter=better. 3. It would be AMAZING if they could partner with Scala or some similar company and offer an integrated blue tooth system in the helmet rather than an add on. This shouldn't be an expensive add on, just look at the general blue tooth speaker market to find a zillion different options for less that $100. February 3, 2015
The Right Fit After going to the New York IMS we got properly fitted and we got some recommendations from the Arai booth I ordered a signet. I was then able to get my helmet and get it broken in. Had to order the slimmer cheek pads to accommodate my face but what a great fit afterwards. It's mildly noisy on different bikes but not really too bad, air flow while moving and again on different bikes seems to be a big variable, but not by far a deal breaker. The protection is absolutely the best and after being hit on the highway by a tour bus and taken out all I can say is all my gear performed perfectly. Take the time to get the best you can afford, it CAN save you in a crash. On a secondary note one of the vents broke, called in and they sent me out the parts quickly and easily. It was a DIY job easy no need to send it back. Overall a great helmet with great features and a company that backs their product up. December 21, 2014
