What's this?

Arai Signet-Q Hydra 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.

Features:

  • 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

Long Oval Heads, Rejoice!
Bought this because I have a long oval head shape and the vast majority of helmets don't fit me.

This one fits perfectly. In fact, now that I have it, I realize I never had a properly fitting helmet before! I've had a few that caused pressure points, and a few that were loose. This one - perfect. It doesn't feel tight, and it doesn't feel loose - it's just right.

Other than that - noise level is less than my previous helmet, but still quite a bit of wind noise.

Visor is crystal clear, gorgeous. Thoughtful vents. Arai quality - all you need to know really.

About the design - this helmet, like most Arais, looks much better in person than on the pics. It's drop dead gorgeous.

First Helmet
A coworker and the MSF guide recommended either and Arai or SHOEI. I previously tried the LS2 vantage which is also rated as a long oval however still presented itself with a hot spot on my forehead after 15 minutes of wear. With this helmet, no such hotspot, unfortunately I think I bought a helmet size too large. There is so much customize-able padding inside the helmet that allows you to create more space inside. I'd say when in doubt go a size smaller. The Large still fits snugly on my head by wind (from my naked bike) at speed cause the slightest of wiggling.

After 3 weeks of daily use one of the vents on the visor popped off while I was riding down the Interstate never to be found again. The helmet gets pretty loud at ~60+mph but for sub 55mph speeds I hardly notice.

Looks great.
This is an excellent helmet. My only complaint is that I wish it had a built in sun visor.

Best helmet
Been riding for over 30 years so I've owned many helmets. Most of them have been Arai's. This one is by far the best.

Awesome Helmet, and Sick Graphics!!!
This Helmet is Fantastic! The graphics are sick. The helmet fit my head perfectly right out of the box, but i was amazed with the helmet's fine tune ability.

The helmet has lots of vents, and it keeps pretty cool.

All my friends are amazed at how light the helmet is compared to theirs.

Overall I do recommend this helmet. It might seem a bit on the pricy side, but you can't but a price on your life.

If you're getting hot spots in the center of your forehead this is for you.
I rode with an RX-Q for two years. It's a fine helmet but after about 20-30 minutes of riding i would get a burning sensation in the middle of my forehead. I figured I had a long oval head shape and sure enough after riding with the Signet-Q for 4 hours my head felt fine. The Signet-Q also has more customizable options in the form of padding removal. The fit is perfect and I recommend it to anyone who gets those forehead hotspots.

GREAT HELMET
THE FIT IS PERFECT FOR MY HEAD. I HAD AN OLD SIGNET AND IT WAS ALWAYS VERY COMFORTABLE. I EXPECT THIS HELMET TO BE THE SAME. THE NOISE LEVEL IS AVERAGE. I WISH I COULD TRY A "QUIET" HELMET TO SEE WHAT THE DIFFERENCE WAS. OVERALL I HAPPY WITH MY PURCHASE.

Not bad
Overall the helmet is good. But I guess its just not for me. It didn't fit my head right. I didn't find out til I was riding, and hit the throttle. It just went back smushed my mouth. I felt like my mouth was already too close. So maybe like I said, this helmet wasn't made for me. Sucks I'm stuck with $400 helmet I cant wear, after just one short ride.

I needed a new helmet for my new black bike. My wife actually picked one up as well because the Shoei she had was leaving a hot spot on her forehead after about 1 hour. This helmet seems to be just a bit more oval and that eliminates the pressure on her forehead allowing for longer rides :) It's my first Arai helmet and I am very happy with the quality. Airflow in this helmet is also amazing.

I needed a new helmet for track days. My Arai quantum 2 is getting old. I chose this helmet based on fit and cool graphics. And I'm a loyal Arai owner for life!

Can the face shield be swapped out on this model for, say, a dark smoke visor?
Mario J on Jun 9, 2015
BEST ANSWER: Yes it can. There are two ways to go about this. First option you can replace the insert inside the face shield, which uses the pin lock system or you can replace the whole face shield. If you look on Revzilla website they both parts. Hope this helps.
Anthony, I'm calling you out. Why after all this time is there no video for this graffic. Don't let Ruben or Brian Vance post a traffics video befor you. I was under the impression Revzilla was the king?
