What's this?

Arai Defiant Helmet

Designed specifically for the aesthetics and needs of street fighter and naked bike rider in mind, the Arai Defiant is equally aggressive and feature rich, as one would expect from a new Arai helmet. Based on the fit and comfort of the Quantum, the Arai Defiant was built for the upright riding position with its aggressive, integrated chin spoiler, which was designed specifically to guide wind around the neck and to improve the aerodynamic properties of the helmet. The Hyper Ridge Bumper circles the bottom of the shell both adding additional strength and also lowering the helmet's center of gravity, while flaring the helmet opening slightly to increase the ease of putting on, and taking off.

The Arai Defiant utilizes Arai's latest face shield design, the SAI Max Vision Pinlock Shield with Brow Vents and includes Pinlock insert lens. The SAI Max Vision shield has been widened by 5mm left and right and offers one of the widest eyeports available for excellent peripheral vision.  

Features:

  • Aggressive new styling
  • Internals are redesigned with a focus on safety and comfort
  • Organic shell shape for superb energy management
  • IC-4 Upper Intake vents seal more completely when closed
  • ACR-4 flow thru exhaust vent allows greater air flow when open and reduces drag when closed
  • FCS R (Facial Contour Support) cheek pad design has 5mm peel-away micro fit layer for greater personal fit
  • Cheek pads feature contoured shape, multiple density foam layer supported by a patented spring
  • Shell shape is easier to put on and take off
  • Water repellent material along bottom edge
  • Pull-down spoiler works with flared bottom to increase helmet stability
  • SAI Max Vision Brow Vent Pinlock anti-fog lens insert included
  • DOT and Snell M2015 certified

Very comfortable... I wore this helmet for days during a 5400 mile ride across the US... it never bothered me even after wearing it for 12 hours a day.. it worked beautifully with the Sena 20s

This is my MAIN, GOTO helmet when riding in the US. I mounted the Scala Cardo G9X to the side and really like the quiet helmet and many vents.

Seemed like a good helmet for riding a HD. We'll see how it work out when it arrives! Thanks for everything!

Arai is one of the best helmets made. If I'm ever involved in an accident I want my head protected!

I only use Arai helmets after my first one, they are great!

The video that the gentleman put on was very informative on this model. Ive always been an aria fan but haven't ridden in many years. I knew when i was going to buy another bike I had to have an aria helmet.
eddie n on Dec 25, 2015
Seemed like a great helmet to wear on my Senna Monster.
Gerald B on Dec 11, 2015
I like Arai's no compromise on safety approach that seems to translate from the track to the street. Additionally, I ride a Speed Triple and this helmet was made specifically for naked bikes. Lastly, I live in the hot, humid southern climate and I wanted a helmet that could provide excellent ventilation.
Bradford P on Nov 22, 2015
Best Protection!
George T on Nov 22, 2015
It fits my round shaped head perfectly! Great field of view, very aerodynamically balanced
Maxim K on Oct 31, 2015

The detailed Revzilla detailed breakdown video! The SNELL 2010 rating, venting features, shield options and most importantly, it fits my head perfectly!

good reviews, have an RX-Q, wanted better circulation...
Dave C on Feb 20, 2015
Long history with Arai; it's the only brand that fits my head. The Corsair V is my current helmet, but was too expensive this time around. The ventilation on the Defiant looks (on paper, anyway) that it will work well.
James B on Feb 8, 2015
Arai is the best helmet I have owned just pricy.
Curtis B on Jan 21, 2015
Legendary Arai quality. Their helmets have never let me down.
Arron G on Jan 9, 2015
Revzilla's Arai size/shape chart doesn't show where this new Defiant fits, but the Revzilla team (very helpful) stated that it's shape is a little more oval than the RX-Q. I ordered both the Defiant and the RX-Q and will pick the best fit.
Jeff M on Nov 29, 2014
Coming from a Icon variant. I do like the looks of the Icon but man its not for me its too big and its not meant for up riding position.Ive read mixed reviews about this Arai so Im hoping some are wrong about what they have said, and the helmet is good for commuting on a naked bikes especially on the highway.
Sammy A on Oct 23, 2014
I thought I've matured enough to have a good helmet. I thought I would keep this one intact forever. I thought I've ironed out all the bugs in my behavior which cause me to do things like drop a helmet. Is what I thought.

J O on Apr 17, 2014
Replaced an older Arai helmet, that I was 100% satisfied with during many years of use. Selected Arai Defiant for the improved venting system. It also has fresh styling improvements and comes with pinlock fog reducing lense system.
William B on Apr 15, 2014
I have owned two Arai helmets in the past and tried this one on in a store in NYC, love the way it fits and know these helmets to be incredibly comfortable on long rides.
Johnny F on Apr 13, 2014
Currently I use a Shoei RF-1100 but began finding the helmet shaking at speed and want something built for a naked bike and hopefully with a little firmer fit along the temple and forehead.
JohnnyYen on Apr 13, 2014
It supposedly fits my head shape and I ride upright on KTM 950smr that its designed for.
Nate R on Mar 21, 2014
Hoping that this lives up to the hype with regard to stability at highway speeds. Also hoping that the aluminum silver looks as good in person as it does in the picture, dark metal rather than bright silver. 2014 FZ-09

Superb ergonomics, ventilation and designed for street and touring riding position with the reassurance of a new Arai product
Marcelo H on Sep 27, 2013
After thorough research this was the brand that I felt would offer me the greatest protection of my brain and it is designed for the more upright riding position and wind angle based on the rider position on my Multistrada.
John R on Sep 9, 2013
I wanted to try the 'Arai' head shape and I am so glad I did! It feels like I'm wearing a tube sock. A really quiet, safe, tube sock.

Just purchased a 2013 Ducati Monster Diesel. After reading reviews and watching the revzilla video reviews, I realized this was the helmet for me. This helmet was designed for naked bike riders.

Revzilla had an excellent video review of this helmet that answered many of my questions. I could have purchased this locally but I found more of my questions were handled by Revzilla. They certainly know their products.

I ride a streetfighter 848 with a shoei 1100 lid. Unfortunately getting lift at highway speeds and am looking to change to either another Shoei GT Air or arai Defiant. Would you recommend one over the other?
Cheers Kim
A shopper on May 11, 2014
BEST ANSWER: I have the Defiant and have had NO issues like that
with mine, best helmet ever worn.
Hi, I'm trying to decide between an RX-Q and the Deviant. I currently have a small Corsair RX (perhaps from 2005? I got it used...) and love the compact shape, snug fit and understated appearance. Since I'm not sure how old it is and it's started to fall apart here and there, I've decided to replace it for safety's sake. Not sure why but somehow $700 is just a bit too much for a helmet, while $5-600 seems manageable and smart.

I'm female, occasionally (once or twice a season) ride the track, but mostly ride 3/4 street (upgraded my Ninja 250 for better performance and more cafe styled), typically anywhere from 20 minutes to 3 hrs on the bike at a time. I wear fitted earplugs, and am planning on installing a Sena smh 10r.
I'll ride in the brittle winter as the bike is my only transportation in New York (Upstate - but not so Upstate that I can't ride dry roads most of the year), so being warm is important to me, but I won't go so far as to get heated anythings, I'll catch a car-ride if it's that bad!

Onto the Q's:
- Is the Deviant TOO ventilated?
- Is the RX-Q a noticeably bigger shell than the Deviant?
- Will either of these be comparable to the Corsair RX in compact shell, cheek fit?
- The pinlock anti-fog lens is included with the Deviant, does this really make the difference? Cold weather brings that out quite a bit, and I've definitely had an issue with the Corsair fogging up.
- I'd like to get a shaded lens insert regardless of which helmet I get, but does the pinlock design make this an easier switch if I'm on the road from light to night or vice versa? (Sunglasses under the helmet make annoying double polarization colors, so I ride without shades in the day. Would be nice to have a quick fix in the tank bag.)
- Pricing btwn the RX-Q and Deviant seems about the same after Pinlock shield is factored in, do you have any other advice based on my criteria?
- Is it worth the extra $1-200 for the new Corsair for my needs?

Thanks for any answers you can give.
A shopper on Sep 9, 2013
BEST ANSWER: -This helmet is not too ventilated since you can close the vents
-The Rxq is actually a noticeable smaller shell than the defiant
-The cheek fit does resemble that of the corsair V
-I find the pinlock to work well for anti-fog, since the built in breath-guard doesn't help that much with colder mornings

One huge determining factor between the Defiant and RXQ is weight. The Defiant is MUCH heavier than the RXQ. Even just holding it in your hand, it is definitely heavier than all the other ARais and most Shoei helmets.
I am looking for a quiet helmet. Regardless of price. I have a medium size (female) head. This one gets decent ratings, so it is at the top of my list. I ride 3/4- upright, street/city riding on a naked bike, and in Southern California heat. Again, this looks like it could be a good fit. Any thoughts about the noise level on this or a recommendation for something different?
A shopper on Aug 10, 2013
BEST ANSWER: I love this helmet! I previously owned an Arai Profile, wich i found extremely comfortable, but noisy. As for the defiant it is extremely comfortable, great ventillation, great visibility(visor) and no fog. I ride a 2012 FJR1300 on mostly highway roads, i keep my windsheild in it's lowest setting. The defiant is much quietter then my Profile was and a worlds quitter then the HJC i once owned. I live in Canada so i can not say how it will be in the california sun, but during 45c temperatures I was fine.
Hope this helps...

I have previously asked about the size and it looks like a medium will be a good fit. However in regards to Shell size or comparison, "If I fit into a Medium Vector 2, will the Defiant fit in the same fashion?"
John R on Apr 24, 2014
BEST ANSWER: I bought this helmet bc reviews said tjat it was the same fit as the rx-q. So I ordered it as soon as it got to my house I put it on and instantly I knew that, that was not true. But I left it on for an hour to give it a chance since it was new I thought maybe the liner needs to settle in. Although that was not the case and I ended up driving to revzilla a little over 2 hours away. And ended up getting the shoei x-12.
I live in Wisconsin and do cold weather riding. Will I stay warm in it? Thanks Hannah
A shopper on Apr 22, 2014
BEST ANSWER: I wouldn't say this helmet is particularly good in colder weather. Even with all the vents closed, a lot of air still moves through it. That being said I used mine on some mid-20 degree mornings with a balaclava and was fine. The pin lock lens 100% works at keeping the lens from fogging up, which was always my biggest problem with my previous helmet.
What about this helmet is designed for naked or streetfighter style bikes? Base on the reviews, it is obviously very loud, which seems contrary to something that was designed to handle the large quantities of direct air-flow you get on a naked bike. Also, the extra venting seems like it would be far more beneficial behind a faring and windscreen where airflow is more limited, instead of completely exposed where air-flow in ample.

Rolling on a 2013 Street Triple R, and love the look of this helmet, but no looking to go deaf in the process.
Thanks in advance!
Alex B on Nov 28, 2013
BEST ANSWER: Most helmet venting systems are located so they are into the wind in a tucked riding position but still aren't very affective at flowing the amount of air necessary to keep the rider comfortable. I ride an M109R without a windshield and my original helmet was a Shoei RF1000 and the venting was horrible even with my head out in the wind. The vent orifices on this helmet are located and positioned for maximum air flow. Behind a windshield, this would definitely be the best choice of helmet given the obstruction from the windshield. On a bike without a windshield, the airflow is extraordinary. It does a phenomenal job of channeling the air to keep the rider cool which is why it isn't as quiet as some other helmets on the market. The noise level is not that loud considering the airflow. -Jason
I have asked a question regarding sizing already and it looks as though I will go with a medium based on Measurement. However just wondering, "If i fit a Vector 2 with a medium, will the Defiant fit in a similar fashion ? :) Thanks
A shopper on Apr 24, 2014
BEST ANSWER: Short answer: Yes as long as you go with the right head shape too.

Long answer: I have an oval head and wear an extra small Defiant. It's snug and very comfortable. Before I took the plunge to buy one, I went to a local mc dealer who had Arai helmets. They didn't have the Defiant, but I tried the RX-Q and Vector 2 in oval shape and tested out the sizing. I thought I was going to be a small because of my measurements, which is right on the low end of fitting into a small. After trying some on, an extra small fit better overall. I ordered the XS oval Defiant from Revzilla and it's been happy riding every since. I really like this helmet.
How well does the Defiant accept bluetooth comm systems? I am considering the Sena SMH10R, Cardo G9, or Intervoice F5 XT. I believe any of these will need to use the adhesive pad as the clamp will not fit, but I am concerned about room for the speakers. Thanks!
A shopper on Nov 20, 2013
BEST ANSWER: No problem fitting the SMH10R in my Small Defiant helmet. Think Oreo cookies. I actually put on the extra little disc padding that comes with the Sena to bring the speakers closer to my ears.
Just remember: everyone has a different shaped head, so if you try putting Oreo cookies in and you just end up eating them as you put on the helmet cuz it's too tight, you should get more Oreo cookies.
I have an RXQ I have been riding in since they came out. The venting is non-existent. I also have an XD3 i find the venting to be pretty good (but I sure hate those fiddly little vent levers). How does the Defiant compare? Trying to decide whether to upgrade to the Defiant or buy a new XD4. Bike is a 950 Adventure. Thanks!
Mark S on Sep 20, 2014
BEST ANSWER: I have been riding RF-1100 for the last few years. Have ALWAYS loved how quiet the ride was, how snug the fit was. Never knew I had "venting issues" until I tried the Defiant.
It was my friend's and the size was a bit off, but I had a pretty good idea of what that huge vent at the mouth was capable of.
I ordered mine within the week and I now ride with it "almost" exclusively. I say "almost" for one simple reason: it IS a bit louder/noisier than my RF-1100.
I would have to say that it depends on the bike.
I ride a 1976 BMW R90/6, no windscreen or fairing to speak of. With this bike, the DEFIANT cannot be beat. I also have a 2011 BMW F650GS, WITH a windscreen. On this bike, no matter HOW I sit, the helmet REALLY whistles. I have to wear soft earplugs. I installed a Bluetooth speaker system... Cardo system. Not the most expensive one. The unit below. It actually helps deflect the wind noise a little. It also works wonders for Bluetooth.
Anyway... Hope this helps.
Personally, I LOVE the DEFIANT. VENTS well and SUPER COMFORTABLE. Just depends on the bike and seat position.
(Oh... on both my bikes the seating position is pretty upright.)
What is the difference between the "White" and the "Diamond White" finish????
Some better photos or someone's feedback would be helpful!
A shopper on Mar 28, 2014
BEST ANSWER: The "white" is just a pure gloss white. The "diamond white" is a pearl with a slight metal flake white. I ride a 2012 triumph street triple in crystal white and it's almost a perfect match.
