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

Bummed I didn't go Arai ten years ago
Arai Defiant
First impression – I’m bummed I didn’t measure my head, check the shape, and have the opportunity to try an Arai before spending the last 10 years in the wrong helmet. My starter helmet was an HJC (L), then X11 (M), then Qwest (M).

Something about me – I go on long rides and the lower register wind buffeting noise causes fatigue and hearing loss. I wear shooting grade ear plugs and recently have been using a Windjammer on the Qwest. It wasn’t enough.

Now for the Arai – The Arai is different from all the other helmets I have seen. Most helmets are pretty similar with slight differences; price, air vent configuration, interior quality, noise, etc. When I moved from HJC to Shoei they were pretty much the same, except the Shoei has higher quality materials. I mean, they’re helmets right? How could they be that different? Arai, that’s how.

What’s the deal with the shield pods? The pods allow the shield to be mounted outside without creating dugouts in the shell – stronger, safer shell. The shield is easily removable. The shield is not bean shaped like most others, but rather has two corners at the bottom edge. Why? Because that fit their engineering needs. The helmet does not “ratchet” with “strong detents” like the Shoei. This does allow the shield to flip up in the wind when half-cocked. So that’s a bummer. But when it’s cracked it stays down. It does lock in place when closed. You do not open it by pressing up, but rather by hooking your thumb under the lock and leveraging it off the lock. This is another interesting engineering choice that makes it unique.

What’s the deal with the egg shape? Less buffeting and much less resistance when head checking. This was a major revelation. I no longer resist the head check – safer riding.

Dual position vents? Every vent has close, half open, fully open. I guess some people will like that. Even the shield vents have two positions. It’s this kind of interesting engineering and attention to detail that make the Arai different.

What’s the deal with vents in the shield? Dude, those things are routed to your temples and are freaking awesome.

Adjustable padding; another difference. I’m not sure if I need to pull out padding yet (still testing) but it’s cool that I can. I did have to reduce these two nubs in the back-bottom of the helmet that were giving my massive headaches. I pushed a straight paper clip under the plastic multiple times to kinda destroy the foam. It worked wonders.

Shell size – It’s much closer to my face. This helps keep the overall size down so your neck doesn’t have to torque so much resistance. Think of the helmet as a lever. When wind resistance is pushing against the helmet it is using your helmet to torque your neck. If your helmet shell is four inches away the wind has a 4-inch lever. If the outer shell is three inches away, the wind has a much shorter lever to push on. What do levers do? Multiply force! The lack of a massive spoiler helps too. Of course the tighter the padding is against your head the more control you have over a lever of any size. Plus you don’t look like a bobble-headed lollypop.

Fold out chin skirt. Who does that? I use is for noise control.

It seems like every single part is unique. This can be good or bad, as evidenced by the love/hate reviews online. But each time I look at a new part; liner, vents, shield, shape, etc. I notice that I haven’t seen any other manufacturer do it like Arai does it. You can tell they solved all their engineering problems in-house without looking at anyone else’s design.

Head size – I tried both the Signet Q and Defiant and there is a massive difference in shape. Do yourself a favor and try both.

Pros –
- Quiet. That could be the Defiant or it could be that I finally got the correct sized helmet. I’m pretty sure it’s due to the facial contour cheek pads, tight neck roll, and fold out chin skirt. I have less noise in the Arai as I did with the Qwest fitted with the Windjammer. I am glad to be done with the Windjammer, but may put it on for long trips. On the downside I don’t hear enough traffic noise. I almost put that line in the Cons section.
- Much less buffeting. I am no longer resisting head checks.
- Massive amount of airflow from all sides. I mean, ridiculous. When the vents are open it feels like an open face helmet. I don’t need to leave the shield cracked for fogging.
- The Defiant comes with the pin lock insert. Most other helmets come ‘pin lock ready’ and make you buy the insert for extra dough. Although with the Arai it’s obviously priced in.
- The emergency pull-out cheek pads are awesome. I can easily pull them out so friends can try my helmet without think it’s freakishly small.
- Adjustable padding.

Cons –
- Whistling is louder than the Shoeis. Admittedly it’s rather annoying. It still happens with the vents closed, just barely.
- Price, I guess… But considering how happy I am I would shell out any price so I don’t really care.
- The chin strap is a little close to my throat. It can be hard to grab the strap snap because the face padding gets in the way.
- I’d be really bummed if I dropped it and it bounced down the road.
- Lack of strong detents in the shield.

Sizing:
Dude, go buy the $2 soft measuring tape at a crafts store. Don’t be a dummy, it’s $2 to help you insure you’re investing your $500 in the correct sized helmet. I was shocked to find out I have a small head, and for the first time I have a helmet that fits like a tube sock. I called Revzilla to confirm and they said definitely go with the small.

Take the cheek pads out before trying on the helmet. The trend towards contoured cheek pads and larger neck rolls are making helmets quieter and safer, but harder to get on. When people can’t get their face in the hole they think they have the wrong size. With the cheek pads out you can test the true size of the helmet.

I’m not sure if Revzilla condones this, but be willing to spend the extra $$ to put two helmets on a credit card, try them on, and ship one back. Use your credit card to hold the swing amount. I tried the Signet Q and Defiant, and my head shape would have been very unhappy in the Signet Q. I wish I had done this with the Qwest I bought 3 months ago, but instead lost $150 (!!) dumping it on Ebay. If I had it to do over again I would have measured my head properly and ordered the Qwest, Signet, Defiant, and Schuberth S2. It would have cost roughly $30 to ship the remainder back, but I would have known for a fact that I had the perfect lid. Be a good guy and ship them back in pristine condition with the tags attached. Revzilla has amazing customer service so be nice back.

I couldn’t be happier. 5 stars all around except the whistling.

There is a reason why it's an ARAI
First off, I have been riding for over 40 years, and over those years I have have had every helmet under the sun ( with the exception of AGV). That being said... This is my first Arai, I can also say that I will NEVER wear another helmet... sorry Shoei!<br>The minute you take it out of the box, you will know why there is only one Arai. The finish is flawless, from the paint all the way down to the controls on the vents... very high end. The fit is perfect... But make sure you give the helmet a chance to break in before making adjustments...It will mold to your head after a few hundred miles... then it feels like butter. The air flow is amazing, I am a bald guy,, so I feel airflow much more then a person with hair...lol. Now I have to say that I never really got the whole "quite" helmet thing... I mean... its a helmet that flows air on a motorcycle... enough said... so I won't really get into that issue.<br>Now about the Arai shield system and the myth that surrounds it... I had it down the first time I tried it, I find it to be much easier then the other systems,, I can change shields in about 10 seconds.<br>Installing my bluetooth system was easy... thin speakers are recommended and rightly so, Arai makes helmets for safety.. pretty sure they don't care about bluetooth systems, and the fact that anyone puts one in their helmets.<br>This helmet is amazing... I will never own any other helmet then a Aria...EVER

Good helmet BUT.........
I bought this helmet under the understanding that it was specifically designed for naked bikes and that the venting is exemplary. I own a Ducati Diavel and I was looking for a replacement to my Schuberth C3 pro due to its poor venting in warm weather (The C3 pro would be perfect if it vented well). My impressions are as follow:

Pros:
1. The helmet is a quality item, no doubt about it!!!
2. The venting is top notch......I just love how air flows through the helmet.
3. In the city and up to legal speeds the helmet is stable and perform as advertised.
4. The helmet is stable when you look over your shoulder to check lanes.

Cons:
1. The helmet is LOUD! You definitely need ear plugs at highway speed.
2. From an aerodynamic point of you, the helmet does not perform as well at speeds above the legal limit. I was very disappointed because I expected the helmet to perform at least as well as my Schuberth C3 Pro (The quietest and most stable helmet I have tried so far)

To recap; this is a good quality helmet with excellent venting and you wont be disappointed as long as you keep it bellow 150km.

NOTE: I have tried the Defiant on my BMW K1600GT and the stability issue at high speed, that I complained about on my Diavel, was non-existent.

Great Helmet
I waited a few months before reviewing this helmet to offer the most accurate feedback possible. I initially wanted an Arai helmet in favor of its subtle, organic shape. I chose the Defiant for its hyper-ridge feature for non-faired bikes & its overall looks.

Its airflow is one of its biggest strengths and quirks. It does a VERY good job of airflow- almost TOO good. It'll even bring in air when all vents are closed & chin curtain is down- something you might not want during very low temperatures. Another quirk is its noise level. Wind noise is very noticeable at freeway speeds, but not to the point where it's uncomfortable. Listening to music wouldn't be a problem, but I would imagine taking calls through a Bluetooth would be very difficult.

Overall I love the helmet, almost to the point that I take its features for granted, such as its Pinlock lens (included with the helmet!), wide-vision visor and plush interior lining. I'm pretty sure any subsequent helmet I end up buying will come up short on points that the Defiant can fill.

This is a great helmet for all riders mainly cruisers or the up right position
I bought this helmet on 5-30-13 and today is 8-28-13 so just about 3 months. The fit is a round fit so if you need more room or space this helmet is great. The noise level is a bit loud on high speeds but on low speeds you will be ok but because it has a lot of ventilation. (Air flow). Weight is fine. The shape is great its has a more round shape to for riders with a more rounded shape head. This arai defiant helmet has an exceptionally wide vision which I love. You will not go wrong buying from revzilla the staff is very knowledgable about the product and if they don't know something they will take there time researching it for you. Hey don't take my word for it call and see your self you won't be dis appointed they are very patient. I will be buying from them again the are the best. If anything just watch the videos they are very helpful. One more the shipping was fast.

Amazing helmet!
Okay I ride a 2015 Ducati Monster 821. I bought a shoei rf1200 and it was great, comfortable vented okay and didn't move my head alot in the wind on the freeway. It was pretty stable. But I wanted something that vented better. So I got this aria defiant. And all I have to say is WOW! With my rf1200 I had to be on the freeway for it to vent adequately as well as tilt my head down so the air could go in the vents better and at speed it would buffer in the wind a little, sometimes more. But this defiant is amazingly stable at speed. It truly is designed for naked bikes in a more upright position. And it vents SOOOO much. Better too! I thought ii tt was going to be loud from reviews I read, but it was only slightly louder not bad by any means. Absolutely love this helmet and highly recommend it if you have a bike without fairings and are in a 3/4 or more upright position riding. But I will say I don't care for the shield mechanism at all. And the shield is thinner that the shoei too.

The new street standard, BUY THIS!
First off, hat's off to Revzilla. No sales tax, fast shipping, and they know how to pack their boxes...don't worry about buying a helmet online.

I retired my 5 yr. old Shoei RF-1100 since I ride 5 days a week in all weather (NorCal weather) and I'm sure the UV degraded it a bit.

This is the new street standard. I don't care what bike you ride; if it's on the street BUY THIS! The Airflow is AMAZING with no fairing protection and about just as good tucked in.

For me, the Shoei fits ON you, this ARAI you fit IN; like a pillow wrapped around your head. It's extremely quiet until about 50 MPH and then some lower range wind noise picks up. I highly recommend wearing No-Noise ear plugs with it.

Price is the only downside. This is the only time I bought Solid Black rather than a design due to the cost. Shoei is "affordable", but with Arai I don't think the extra $130 is worth it ($700 helmet design...craazzy).

Wow, what a great lid
I've always loved Arai so I'm nothing like an objective, unbiased reviewer. I recently picked up a Signet Q based on what I *thought* was my head shape - apparently Arai and I disagree on the definition of long oval, which I've been seeing a lot of on other Signet reviews. A local shop custom-fitted a Defiant for me and the difference between it and the Signet was night and day. Spirited (ahem) riding on my R1100RT with the windshield fully down was blissfully smooth and quiet (but I do recommend good foam earplugs with any lid), great airflow, excellent visibility, and the most comfortable padding I've ever felt aside from my beloved old Quantum.

Simply the best helmet I've ever owned in 20+ years of riding, period.

Fantastic! Arai has done it again.
The Defiant is a well thought out helmet. Before this purchase, I have been wearing the rxq happily for some time now. Its quiet, light weight, great ventilation, and wide visibility. My only complaint was how strained my neck would get on the freeway pushing against the wind. I ride a triumph triple so its more upright position. My only complaint with the rxq is now taken care of with the Defiant! The new shape of the outer shell makes a huge difference on the freeway. I don't have to push back at the wind nearly as much, it actually now feels like my head is moving 'between' the wind! Super quiet and very comfortable the Defiant is the best I have ever worn.
