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

Arai Signet-Q Basilisk Helmet 4.8 5 303 303
Signet Q Pro Tour - Glasses Wearing Commuter - Good Option I bought this helmet for two reasons: 1. It was time to get a proper helmet and stop wearing my old autocross helmet. But, if that was the only criterion, a much wider net could be cast searching for the right one 2. As a glasses-wearing commuter rider, I chose this because of the external sunshade. I didn't want to carry around sunglasses every time I rode anywhere. Now, a few comments about it. Fit of the helmet is great for us long, narrow oval types; Arai makes a helmet for every shape and this fits me. My genetics make this a good fit. Bearing that in mind, if this helmet fits your head shape, it fits well. It's snug all the way around after a brief break in. Much quieter, lighter, and overall more comfortable than my previous (though not a fair comparison). Regarding the feature that made me select this, the external sun visor, I have a few additional comments. First, I think it looks a little dorky (but the camo offers a nice balance). I'm still trying to convince myself that if it's light enough to see the visor up, tough, then I'm likely going to have the visor down. That is, the only time the visor's up and is in the dark. ...and I look great in the dark! In full sun, the visor isn't as dark as I'd like, making me still need to squint a bit due to brightness. Also, others have mentioned that it doesn't cover the entire field of vision, but it's still pretty good. I do get the occasional glare from the gauge or something else, but all told it works as it was designed. To that end, I don't carry my sunglasses anywhere unless I'm going to wear them off the bike, too. So, I think the helmet is a good solution for the glasses wearing commuter rider. The helmet vents well for being as snug as it is, though I have yet to wear it in hot weather. It's light, and the field of vision is much wider than my last bucket (again, not a fair comparison). In total, I'm satisfied with the purchase despite groaning a bit at the price. Hopefully it holds up well, and so far shows no sign of issue during the ~1 month of riding. January 19, 2016
Arai Never Disappoints I've been wearing Arai helmets for over 10 years and I've never been disappointed. Their quality is absolutely TOP NOTCH. December 11, 2015
arai Very comfortable, light weight, and comfortable. Pin locks works great. November 23, 2015
great helmet for long oval head shape This was my first Arai helmet ever and I am pleased with it. I took it on a 2500 mile trip this summer just after purchasing it and I would say that no break in period was even needed for me to see positive results. I have a long oval head shape, and other helmets have been miserable, putting too much pressure on various head pressure points. I can comfortably ride 100+ mile stretches without needing to constantly adjust the helmet to relieve pressure like on other helmets. If you have a long oval head, this is worth the investment.

Great helmet This is an awesome helmet. I've used a couple different brands and this one is by far the most comfortable to wear and has great noise reduction. It's very easy to adjust the airflow while wearing it and riding if necessary as well. October 26, 2015
Nice fit for long oval head I chose this helmet because it specifically was designed for long oval head shapes, which I have. I like the fit of it very much. My bike is in the shop right now, so I can't comment on the rideability aspects of the helmet yet. October 20, 2015
Good helmet, but not a Profile fit. I previously had an Arai Profile and this helmet is a nice upgrade as it's much more quiet and the sun shade is a nice feature. But, be warned, this might be a long oval, but it's not a replacement for a Profile as it fits much more snug than the Profile and has left me with hotspots in the back of the head after longer rides over 1.5 hours (with my profile I could ride all day long). If the fit was more like the Profile, I would have given it five stars. October 14, 2015
Excellant helmet! Was debating for a while to get this helmet as my previous one HJC 10 was fine. But am very glad I did! Use it for street and track. Fit is perfect for my head as I've only found a few that are truly comfortable. Overall quality is great, vision is great, airflow is great, nice attention to detail everywhere. Chin strap is comfortable too. If you're thinking about it, get it you won't be disappointed. Wish I got it sooner. October 9, 2015
