What's this?

Arai Defiant Asteroid Helmet

Designed specifically for the aesthetics and needs of street fighter and naked bike rider in mind, the new Arai Defiant Asteroid 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 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 faceshield 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
  • New IC-4 Upper Intake vents seal more completely when closed
  • New 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
  • New shell shape is easier to put on and take off
  • New water repellent material along bottom edge
  • Pull down spoiler works with new flared bottom to increase helmet stability
  • SAI Max Vision® Brow Vent Pinlock anti-fog lens insert included
  • DOT and Snell 2010 certified

Great naked bike helmet
You know how good Arai helmets are. For the more upright position of a naked bike like my Ducati Monster, this is perfect. Plenty of airflow. I live in Texas where it goes into the 100s. My head does not feel overheated.

Pleasantly Surprised
After watching the review on this website, I was confident in my purchase before it even arrived but was blown away after I put it on and took off on the Speed Triple. So quite I can't enjoy the sound of the Arrow exhaust I just installed. Ventilation is superb.

Excellent Helmet, cool look, great value!
All my previous helmets have been Shoei. In my opinion, their current generation of helmets such as the X-12 have taken a step backward because there is no feasible visor shield vent position. I wish they had just left the visor mechanism alone. Much preferred the shield on my X-11&R-1000. For the price their charging for an X-12 it should come with AC unit built in! I wish I didn't own one.
That's why this time around I got the Aria. It has a decent visor vent system. Glad I did! It fits my head better and is easier to get on and off. Not to mention it was a lot less expensive! Shoei better get there Sh** together because all around the Aria is a better helmet. Aria is a smaller company and in direct competition with Shoei which is huge. At the moment Aria is offering the better value by a few hundred $$. I am not affiliated with either Co.

1 week use of the Arai Asteroid (Green version)
Summer time desperation buy due to emergency need for a new helmet.

As far as looks, mostly positive feedback from other riders and the general public. No negatives expressed so far.

The green is more of a neon, so it doesn't really match Kawasaki green 100% up close anyway.

Positives:
1. Reduced fog compared to non-pinlock helmets (not 100% but 95% I'd estimate and any fog buildup eventually disappears)

2. Good peripheral view (better than it's competitors in the same price range - sale price)

3. Very comfortable fit - for a medium, intermediate oval which I wear in other similarly priced brands.

Negatives:
1. LOUD - it's definitely louder than other brands, including my older RF-1000 (Jay Leno probably loves this kind of road noise but I prefer hearing music)

2. The visor lock is a pain, trying to unlatch it with summer weight gloves is a near impossible task

3. I ride vintage bikes & sport bikes. This helmet is not great in the full tuck position, so Revzilla's Youtube review is spot on - full upright to 3/4 tuck is what it can do.

I've bought 3 Revzilla reviewed products this year and Revzilla has been 95% spot on in their reviews so far.

Well built but noisey
I loved the design and the construction seems solid but in use the blunt face creates a high level of noise. Even ear plugs could not reduce the sound to a level that made the helmet a favorite. Today it sits on the shelf while a lesser helmet serves the purpose.

My buddy has this helmet and its very comfy, I have to say its a little high in price but at the same time whats your noggin worth? I wasn't able to try all the vents out and really get to know the helmet, but for the time I used it about 2 hrs on his 636 It sold itself to me.
Charles P on Sep 26, 2014
this helmet is the best I have ever had. I had to wait for over a year to order it as no one had it. I checked all sites for over a year and revzilla had it first.
