What's this?

Arai RX-Q Helmet

The Arai RX-Q (the round-oval shaped cousin to the Signet-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 RX-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.


  • Completely new helmet based on Corsair V shell
  • Same wider eyeport opening as Corsair V
  • Same face shield as the Corsair V
  • Intermediate Oval Fit (same head shape  as Quantum 2)
    • Slightly different feel due to new cheek pads
    • New cheek pads come down further and cradle the head better
    • Made of a different density material which results in an extremely comfortable and quiet helmet
  • Advanced ventilation
  • Smaller, more aerodynamic shell shape
  • Hyper-Ridge circles lower shell to improve strength and aerodynamics
  • Retractable chin spoiler
  • Emergency Cheek Pad Removal system along with removable neck roll
  • One piece bottom edge trim
  • Race helmet for the street
  • 5 unique size shells (XS, SM, MD/LG, XL, 2XL)
  • Snell M2015 and DOT

NOTES: The Pearl Black color listed for this product has a very subtle metallic flake whereas the Diamond Black color has a more pronounced metallic. Also, helmet does not ship with the Pinlock face shield as shown. Pinlock face shield sold separately.

This is my first Arai, have always hear good things about Arai, but always wore Shoei helmets because they fit better. But I haven't tried them I awhile.

looks like a great helmet at a closeout price.
Kelly J on Dec 25, 2016
Arai helmets offer great rider protection as well as comfort and if you add noise reduction and good ventilation during the hot season, you are left with a great helmet at a very reasonable price. Additionally, RevZilla has great reputation for providing competitive pricing and fast shipping. Thank you.

Best fitting helmet I have ever owned. Very quiet, very comfortable.
Shawn5170 on Aug 28, 2016
I tried an Arai helmet about 20 years ago and have been using them since. Once you determine your head shape and try the appropriate model on you'll find out why so many people are in love with their Arais.

This is a replacement for my wife. She has tried many helmets and the RX-Q is her go-to. And since it appears they are being replaced, and there is a little price relief, it was time to get her a second one.
STLWING66 on Jun 17, 2016
I need a rounder helmet. I would love to have found an old Arai Quantum II, but no luck. I am "trying" the RX-Q in the hope that it is similar enough in shape to accommodate my round head.
Richard B on Jun 17, 2016
Arai is considered one of the best (if not THE best) helmet manufacturers in the world. User safety is their primary concern. I figured since I only have the one head I should protect it as best as I can.
Aaron T on Jun 16, 2016

Love Arai quality so ordered this to replace my Quantum 2. Not quite as good a fit for my roundish head but trying to make it work with the thinner liner.

Hi, what is the difference between the RX-Q and the Defiant helmet? And which one would you recommend someone who rides a ninja 300. Thanks
Ricky C on May 25, 2014
BEST ANSWER: Really doesn't matter what you ride. How much do you value your "squash"! Get a helmet that fits correctly with the most protection.
I've had this helmet for about 3 months or so and I've noticed a major wind noise that completely blocks me from hearing my bike or any other noise from that matter at a mere 20mph+. How can I eliminate this noise or at least cut it down?
Donald A on May 18, 2014
BEST ANSWER: For me the comfort of the RX-Q outweighs the wind noise on the highway, so I grabbed a pack of the orange "squishable" earplugs and pop a pair in my ears loosely before a ride. That way, it cuts out the noise without the underwater effect of completely blocking out all sound, and they are also very comfortable. Just a thought...
I only have one question guys. Does it whistle in high speeds? I am not referring to wind or engine noise..
Thank you so much :)
Faisal A. on May 6, 2015
BEST ANSWER: I don't notice any whistling. It's a really great helmet, and probably the safest one you can buy. It's comfortable, super quiet, and the field of Vision is excellent.

That being said, in brutal honesty, if I had the opportunity to spend that much on a helmet again I probably would buy a really nice modular. I'm a big guy and probably take up more than my fair share of oxygen. I have a huge problem with my visor fogging up. In cold weather, it fogs then freezes. Full face gets so warm and smothering too that I never wear mine anymore. I always wear my skid lid (half helmet).

This is probably the safest helmet you can buy, but it ended up dangerous for me as I never wear it. Before I had the skid lid, I would just go helmet-less. Not good!

If you're used to wearing full face and you don't fog up too bad, this is THE BEST of the BEST!!! Great ventilation too with no whistling. Only full face helmet I could find that when all vents are open, you can actually feel the wind in your hair.

Greetings from Colorado. I currently have the Arai Vector in XL would this helmet fit similarly?

Thanks in dance for your help.

A shopper on Mar 20, 2014
BEST ANSWER: I am not familar with the Vector helmet in that I have not tried one on. The Arai line uses the same head demensions for determining the size for each of their modles. The Difference comes in the different modles fit different head shapes. I went from a Quantum 2E to the RX-Q and its a great repalcement as both helmets are for a round/oval head shape. The Vector is more intermediat oval and though the circumference of the XL Vector and RX-Q may be the same, the fit won't be the same. I tried on lots of helmets on multiple occassions and though the Arai Defiant is supposed to fit the same head shape as the RX-Q I found it to be more oval in shape and not as good a Fit for my Quantum 2/RX-Q head. If you ride a in a 3/4 to uparight riding position the Defiant might be a better choice for you. I loved my Quantum and the RX-Q is even better.
Can I purchase the RX-Q with the thinner cheek pads or do I have to buy the helmet with the thicker ones and purchase the thinner ones seperate?
A shopper on Feb 9, 2012
BEST ANSWER: To directly answer your question, I don't know. I know they can be ordered as an accessory.

Mine came with the standard cheek pads. However, the stock pads are easily made thinner by removing different thicknesses of foam from them. The cheed pads are made so that this is an easy adjustment. The first thing I did was disassemble the helmet. I believe the first section of foam that can be removed is 5 mm thick.

For what it's worth, I initially thought my pads might be too tight. I left them as delivered. Don't know if I just got use to them or what, but almost 2000 miles later, they are still stock.

Great helmet, but I will be buying pinlock shield with insert to handle fogging in this cold weather riding.
I noticed that "TommyHolly" reveiwed the Arai RX-Q Helmet and mentioned that he uses the Sena but not how he has it attached. Thanks.
A shopper on Aug 1, 2011
BEST ANSWER: I have a Arai RQ-Q helmet (and an older Shoei RX-700)... I also recently bought a pair of Sena SMH-10 Bluetooth Headsets and they fit great!

The clamp on the side easily will fit the Arai helmet and pretty much any other helmet you can think of. There is a slight 1-2mm gap at the top of the headset where the helmet starts to curve in but that doesn't affect wind resistance, noise, or anything else. Attaching the earbuds inside of the Arai helmet required the supplied sticky velcro pads that came with the Sena because the material the helmet is made from doesn't work that good with velcro. The Shoei material worked fine with velco and I could attach the headphones anywhere without a stickypad.
As usual I'm between a M and L . Is it best to go up or down in size?
A shopper on Nov 15, 2016
BEST ANSWER: I ordered a Medium because I wear a 7-1/8. My head was a little too loose so I had to buy the internal head lining with thicker pads for it to fit correctly. So if you're in-between sizes, I would go with a Medium since they seem to run just a little bit loose. If you find it's too snug, you could replace the head liner with a thinner head liner and you should be good. That's just my thought. I'd go with your gut feeling.
What's the difference between white and diamond white? On picture, diamond looks whiter.
Benny C on Sep 23, 2015
BEST ANSWER: I bought my RXQ over a year ago. As I remember the White and Daimond white are both very pure white in color. The difference is the Daimond White is very metallic where as the plain White is not. To me the white is the same except the metallic of the Daimond White makes the helmet stand out in the right light.
Does the RX-Q have molded speaker pockets? Other reviews on the web seem to point to the removal of the cheek pad and then they "appear"? I have taken one apart (from 2015) if it makes a difference and see no molded pockets? The Sena 20S has bigger speakers so this could be a problem. I hope I am just missing something.
A shopper on Feb 23, 2015
BEST ANSWER: Remove the cheek pad. then remove the cloth covering of the cheek pad. The pocket is in the removable cheek pad and hidden by the cloth covering.
It seems the white helmets are mixed between diamond white and white. I do not want a glaring white helmet, so which white, the diamond white or white, is the off-white?? (Color on this rx-q page may be reversed because it seems the white is really off-white.)

Please advise.
Thank you.
A shopper on Jan 5, 2014
BEST ANSWER: hello...the "white" helmet I purchased is gloss white...definitely not off-white.

I don't reckon it to be "glaring"...but it is a pure white

hope that's of some help..cheers
