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 5 5 3 3
Great Airflow and Graphics Fits snug but still has excellent airflow. Sound levels are very good. Typical Arai quality. The pictures on the website do not do justice to the graphics or colors. . The graphics really are incredibly detailed. Cost is definitely on the high side but it is worth it in my opinion. I was talking to an Arai rep at a local shop and he made a profound statement that has stuck with me. He said an Arai helmet is one of the few things in the world that no matter how much money you have, you can not buy a better one. June 30, 2014
Amazing! This helmet is amazing. I went with the green one to match the color of my bike. Looks great! Its weight is good, the airflow is really great! Comes with the anti-fog screen on the side that you can stick on to your visor. You get the DVD for the helmet that explains everything. Only thing I can say about this helmet is that the noise level is a little bit high. Its manageable, but as any helmet on the highway, you will hear the wind. June 8, 2014
Very noisy. The vents whistle badly when the face shield is open. The Defiant fit is perfect for me. The shape is very comfortable without any pinch points or hotspots. This is my second Arai helmet and the quality has always been the best. The one thing that I don't like is how noisy the helmet is. It will whistle very loudly if the face shield is not completely closed. April 7, 2014
