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

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.

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. July 29, 2013
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. July 9, 2013
