What's this?

Arai Defiant Chronos Helmet

Detailed, precision clock like inner workings hide beneath the surface of this new design. The Chronus graphic look sharp from a distance, but offers surprising detail up close for those who appreciate attention to fine detail. 

Designed specifically for the aesthetics and needs of street fighter and naked bike rider in mind, the Arai Defiant Chronus 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

Arai Defiant Chronus Helmet 4.7 5 141 141
simply, i love it everything as expected, slightly large, great material, good locks, and really light and comfy I highly recommend it April 20, 2016
Favorite Helmet I've owned three Arai Helmets. This one is my favorite. I find it fits great, is very comfortable, and relatively quiet. I love the pro shade and visor. The ventilation is excellent also. Style wise, I was a little turned off by the "wing" on the rear but have gotten used to it. I'd highly recommend it. April 17, 2016
Awesome helmet! This helmet is great. The fit and finish is excellent. I was deciding between this and a Schuberth C3 Pro however this seemed to fit me better. It's not the lightest helmet I've tried but it's certainly not heavy by any means. The plush padding and inside make the helmet so comfortable to wear even on long rides. It's pretty quiet and the Pro Shade system is truly functional. I'm by no means a speed demon but I can say up to 90mph it remains still without vibration and noise. I'd certainly recommend this product! April 16, 2016
ARAI does it again I purchased this ARAI Defiant Chronus Helmet b/c I always wanted to try one, mainly b/c I've been a Shoei fan all my life, I'm 54 so I've got over 35 years of riding under my belt both on and off road. So to the helmet, it fits like it was made just for me, seriously, it fits me that good. Its high quality, comfortable and the Red & Black graphics look awesome. I've only had it on 3 rides living here in MD, waiting on warmer weather for the true test, long rides etc... I do recommend this Helmet and now I have the best of both worlds for my 2014 R1, 2006 GSXR 750 and 2006 GSXR 600, not to mention the 2015 Road Glide. Ride to Live and Live to Ride !

Great Helmet Noob to the motorcycle world, wanted to do it the right way starting with gear and wow what a great helmet the attention to detail with all the air flow and pinlock design are outstanding. I removed a layer of the cheek pad to better fit my face and it was very easy to do so. Arai rocks! Expensive but worth every penny. April 6, 2016
Helmet gets noticed. Love the black & white scheme with a touch of red. Compliments my bike. Airflow is great. Cools around the temple. Gets noisy at highway speeds, but I have ear plugs, so it's not an issue. Fits perfectly, and with Arai, the pads are adjustable if you really want to fine tune and tailor the fit. Vents are easily adjustable and accessible with the left-hand. Inner mirror fogs up a bit. I've installed the anti-fog pin lock, and don't have an issue but at night, there's some light distortion, but you get used to it and becomes a non issue. Would highly recommend this product. April 6, 2016
nice, comfortable helmet This is my second Arai helmet. All of the adjustments for air flow work great. It stays quiet until about 85 mph, then gets quite loud. Other than that, it fits great and is very comfortable. April 5, 2016
Best Helmet I've Owned Wow, I've never coughed up the money for a true top of the line helmet, but this was more than worth it. Pros: Style Comfort - Soft and light, with very little wind drag Noise level - It is quiet, but I would still recommend wearing ear plugs above 55mph, it is not silent. Air Flow - Air flow is great, but the helmet is much louder with the vents open. Cons- Visor is a little intimidating to remove/replace Chin strap can be difficult to clip The cons say it all. This is a great helmet, I've been wearing it for 3 months now and I've never looked back or regretted my purchase. I highly recommend this product. March 29, 2016
