Arai Defiant Helmet - Solid Colors

Designed specifically for the aesthetics and needs of street fighter and naked bike rider in mind, the new 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 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
In search of a replacement for my 707 vendetta 2, and wanting to upgrade to a high quality helmet, I bought a Shoei GT air helmet. Ended up exchanging for the Arai Defiant. I overlooked Arai at first because of the price, but this is definitely a helmet worth saving up for. I always thought Shoei was the go to helmet, but in my opinion Arai makes a far more superior helmet. The fit and finish is outstanding, exacty what you would expect to get out of a helmet in this price range. Keep in mind, I have only worn cheap helmets and don't have experience other than trying helmets on at the store. Even so, I think I'm sold on Arai for life.

This helmet is by far the best helmet I've ever had. With all the vents open, it almost feels like a 3/4 helmet, the air flow is excellent. Extremely comfortable, no pressure points (this is relative to me, your mileage may vary if you have a different shaped head) The padding is well thought out, allows plenty of air space for the ventilation system to work.
This helmet is extremely stable at highway speed, even during head checks. Hardly buffets at all. I ride a bike with an upright seating position, with little wind protection. My vendetta 2 buffets at highway speed, and the GT air also had the same issue, but more pronounced when doing head checks. Arai Knows what they are doing when it comes to Aerodynamics.
I think the more rounded shape really contributes to that. I can do as many head checks as I want, and I never get the sensation that the wind is "catching" anywhere on the helmet. Feels just as stable sideways as it does looking forward.

No strange whistling noises unless you like to ride with the visor up.

Nitpicks:
The vents are kind of a pain to find and operate with or without gloves. The drop down chin curtain doesn't seem to make a difference, but it is a neat concept.

I'm not sure how warm this is helmet will be in the winter, because even with the vents closed it still flows quite a bit of air. (That's the only reason I didn't give this helmet a five star rating)

I have yet to ride with it in the rain, so I'm not sure how good the neck roll will work, it is supposed to be made out of hydrophobic material so it won't absorb water. Also not sure how well the helmet will seal out rainwater in a downpour.

Over all, Excellent helmet. If you can try it on, and it fits your head without any pressure points, you won't be disappointed with the Defiant. As stated before I think I'm sold on Arai, I don't think I'll ever get anything else from now on.

PROS: Light Weight, Comfortable, Aerodynamic, great ventilation

CONS: High Cost, Warm Weather Helmet
