Arai Defiant Chopper Helmet

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

This a great helmet!!!! No need to carry 2 visors. The shade feature is excellent and has great visibility. Helmet is very comfortable and fits great. The only concern I have is when using my Sena 20s, the speakers do not sit far enough in without bothering my ears. I had to modify the depth to make them fit better. I called Arai to see if the 15mm cheek pads have a thinner base, but they said that the only difference is the thickness of the removable pads. Other than this, this is an excellent product.

Insane Air Flow. I have this helmet for 2 months now and it is very different from anything I ever had. Air flow was mindblowing first time I got up to 50 mph. Air blows from every angle and and sometimes straight into your eyes. You cannot completely seal this helmet. Even with all vents closed there is more airflow than my Shoei RF1100. This is great helmet in the summer at moderate speed but I can't imagine wearing this helmet on a long trip. Dark visor screen works good when it's down but makes noise at higher speed if you have it lifted. I don't ride without earplugs. Styling is superb. If it matters, I get a lot of compliments. Interior is very luxurious and has by far best feel from any helmet I use. There is only one pressure point on my forehead that feels uncomfortable after about an hour. Other than that very good fit. If you like lots of Air in your face this is your helmet. If you ride in cold days like I do, make a pass or use this as a second helmet. September 17, 2015
Fits a great niche So...I researched & tried on all sorts of helmets when it came time to pick up a new bucket to replace an old Shoei. At some point, the options become almost overwhelming. I eventually narrowed my choice down to a handful of manufacturers, all of whom had great reputations for safety. My key criteria, after safety, was flow-through/coolness, wind aerodynamics, & overall comfort. The Defiant ended up making the final cut because it vents so well & because it's terrific at highway speeds. It's also super comfortable. Here are the possible downsides: the styling may not be for everyone. It's a little aggressive and un-Arai-looking, but to each his own. It's also not the quietest helmet out there, but it's not bad. If you're looking for a helmet to keep your melon cool when riding upright-ish & exposed to the wind, aren't willing to compromise on safety & aren't super budget restricted, make sure to try a Defiant.

Great helmet I bought the helmet based on Arai's reputation for safety and their design of this helmet for naked/minimally faired bikes. Watch the video to see just how much technology is in this helmet. It is well worth the price. August 19, 2015
I am happy! This helmet has everything I wanted. Safety, looks, features. I ride daily to work and am enjoying a more quiter ride with almost zero head shake. Some of that can also be attributed to the PUIG windscreen I also installed. I let my wife wear it once and she likes it too. August 16, 2015
Great Style, Great Protection Having owned other Arai helmets, I liked the styling and pro-shade features of the Defiant so I decided to purchase and I was not disappointed. This helmet fits very similar to the Signet Q and is very quiet on the road. The looks are killer. As Anthony mentions in his video, although the helmet is finished in mat colors, there is a hint of metallic in the finish to add more pop to the overall look. The Pro-shade works great but isn't a very dark tint and I like to wear my sunglasses under the shade on bright sunny days. The shade coverage is adequate but could drop a bit further down the mask. Overall, this is a high end, high quality helmet that is very comfortable and quiet. August 10, 2015
Mixed Feelings about this helmet To be honest, I bought this helmet for the reputation of Aria and that it had Orange in it! Which is hard to find. The things I have been disappointed in: It's LOUD at high speeds. Louder than my previous Shoei for sure. The paint chips so easily. Be careful, don't even let your girl bump her helmet on yours cause it will cause a chip. BUGS fly in so easily. This is probably my biggest complaint. The vents over the mouth have no screen filter, so if it's open and it's dusk on the highway on a hot day, they're in your mouth, eyes, or whatever they can get into. HATE that about this helmet. As for the things I do enjoy: Very comfortable. Fits snug and perfect for me. Moves well in high speeds, better than my last helmet. Lots of vents, though in the summer, I don't notice a whole lot of airflow. And great wide view. August 4, 2015
Glad I upgraded I was hesitant to spend the premium price on a helmet. After having ridden in it for 600 miles I am glad I did. The quality and comfort of this helmet is by far the best I have ever had. The peripheral vision is excellent and I really like the pro-cruise shade, it also gives me cutouts for my speakers! The ventillation is spectacular. Best money I have spent yet! July 19, 2015

Richard P: No, they can't be removed and it is not a decal. I've gotten hit by a few small pebbles while on the road and the black paint was scratched. What showed through is the silver paint under the scratch so I think that might be the base layer. Excellent helmet. Apr 10, 2015
