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

Great helmet for Las Vegas
This I believe is the best helmet I have owned and I've had quite a few. The fit is great although some times the breath shield tickles the tip of my nose but not often enough to be an issue. This is a GREAT summer helmet breathes better than any helmet I have worn very cool during the summer months (120+ here). That said it is now cooling off and even with all the vents shut there is still a breeze inside around my upper lip that I cant get to go away. Living in Vegas this is not an issue as it's only cold here for 2 months. Now let me tell you about why I love this helmet. It cuts right through the wind and it gets windy here. In my old helmet the wind would buffet my head all a round and make it very difficult to look forward (a real pain in the butt around turns) this thing cuts right through. It actually allows me to ride better! My only other issue wit the helmet is with the pinlock system installed (both clear) there is a bit of a starburst effect at night when approaching head/street lights. It's not at all debilitating but it can be a bit distracting. In all fairness my night vision is not the best so it probably bugs me a little bit more. Been riding with the smoke pinlock it's not dark enough (they never are for me) and there has been zero fogging so that feature seems to work well.

replacement for my Vector 2
Vector 2 used to pinch my ears on long rides, so I went for this new Defender, which I was told is slightly rounder. It worked. I just returned from a 1400 mile jaunt. Love the feel of the helmet, the new features, new ventilation system works well. Maybe a little noisier than the vector 2 and the field of vision for some reason does not seem as good to the sides as the Vector, but they use the same face shield so maybe it's my imagination. Ventilation was great, but days were not too hot so can't say more than that. Also not fair to comment on protection/durability because I have no idea beyond Arai's great reputation.

Perfect replacement for Long-Oval Profile/Signet Lovers
The Arai Defiant is the long awaited replacement for my aged Profile helmet. If you're an "Arai head" i.e. long oval, you _have_ to try this one. As always, I'm thrilled with RevZilla service! I got an e-mail availability notice, ordered & had the helmet 3 days later. It's a _perfect_ fit (BTW, I wear a XXXL).
But wait...there's more - a clear Pinlock anti-fog visor was included!
Anthony - you & Team Zilla ROCK!

A shopper asked:I have seen your videos on both the Defiant vs RX-Q. I ride a F800R. Im leaning more towards the Defiant becuase of looks but stacked up against the RX-Q , aside from style, any diferences to point out that can help me clairfy my purchase? My commute is 20 miles but through NYCApr 24, 2013
Christopher L:I've done quite a bit of research on both products. It seems the Defiant is far superior in terms of design. It's not just "style." It's the function of that style: the adjustable chin curtain to keep excess wind out (might be especially useful on colder days with your naked); the "diffuser"/spoiler @ the base of the helmet for increased stability and noise/turbulence reduction; HEAVY ventilation (possibly the best Arai has to offer...yes, including the Corsair V) due to the monstrous chin ventilation system (three stage: closed, partial open, full open); and from what I can tell, it looks like the vent controls would be easier to control with gloves on.
Bottom line: I have a 2010 Z1000 (nearly 20,000 miles) and a 2007 CBR 600RR with 56,000 miles on it. ALL these miles have been put on with a Shark RSR2 (thick visor, decent ventilation, awesome looks w/the Duhamel white graphic I got, PERFECT fit and comfort, easy visor swap, etc. etc.) I love the Shark and will be having a real hard time finding its replacement. I'm tedious in my research and after fitting many models (haven't fit on a Defiant) and reading about ALL top-line models it's come down to these (for me): Schuberth SR1 and Arai Defiant. The fit for the Defiant is hopefully identical to the RX-Q (which fit me better than a CorsairV) which is the shell it's based off of. Haven't fit on an SR1 but from what I can read, it's "race" fit is superb. Good luck with your decision. Just remember, when dealing with the top-line model of almost anything, you're not going to make a bad choice, it's just that one will be wiser for you than the others. Just figure out which one.May 27, 2013
