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

Way too loud for a premium helmet. Extremely disappointed.
You can't return helmets after riding with them which is a problem for this helmet.

Medium fits me extremely well. Arai has awesome fitment.

Air flow is fantastic good features but man is this thing loud at hi-way speeds. Loud to the point you need ear protection to protect your ears from damage.

To compare I have a 3/4 open face helmet and on the hi-way wind obviously slips by to the ears making it noisy. The noise with this helmet is equal to my 3/4 but it has more of a buffeting noise making the noise feel more damaging to my ears. I have tried placing my head in various positions to avoid this and cant.

It's apparent that this is an engineering design flaw for the helmet. The noise appears to be coming from near the covers of the visor mechanics. I'm quite surprised this wind noise issue slipped by the R&D and quality control process as if you look at other Revzilla reviews there are quite a lot of complaints of the defiant being noisy.

For the street and no hi-way the helmet performs quite well and is a joy but for a premium helmet it should excel at both street and hi-way which is why I don't recommend it and why my overall score is low because now I have to sell it used and lose money on the purchase and then buy an rx-q which has significant praise of being a quiet helmet.

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.

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.

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.

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.

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.

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.

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.

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.

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.

It supposedly fits my head shape and I ride upright on KTM 950smr that its designed for.

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

The ARAI name is all that needs to be said here.....

Superb ergonomics, ventilation and designed for street and touring riding position with the reassurance of a new Arai product

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.

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.
Stephen V on Aug 26, 2013
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.

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

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

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

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!

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.
