Shoei GT-Air Inertia Helmet

Enjoying the ride is what motorcycling is all about and having a helmet that is comfortable and safe is just facilitates that enjoyment. The Shoei GT-Air has been designed from the ground up to be the ultimate all-rounder. With a fully adjustable ventilation system, drop-down internal sun visor, fog-free Pinlock CNS-1 face shield and Shoei’s legendary comfort and quality, the GT-Air has all of the features you need to keep your focus on the road instead of on the discomforts a lesser helmet can cause.

The Shoei GT-Air was developed using wind-tunnel testing at Shoei’s state-of-the-art facility in Japan which lead to an aerodynamically tuned tri-composite shell that mitigates buffeting, as well as wind and road noise. The plush removable liner is comfortable, quiet and removable when you need to wash it. Light, safe and comfortable, the Shoei GT-Air meets and exceeds the needs of contemporary riders, allowing them to enjoy what they love most…the ride.

Aerodynamic Shell Design:

  • Aerodynamic properties are maximized through extensive wind tunnel testing and professional riders’ feedback
  • Multi-Piece EPS liner enhances impact absorption and ventilation
  • Three shell and four EPS liner sizes provide increased fit options that help to comfortably fit most head sizes
  • Molded air spoiler reduces drag and lift, as well as diminishes pressure on the rider’s neck while riding at speed

Sun Shield Visor System:

  • Built-in QSV-1 sun shield gives riders instant relief from sun glare in one quick motion
  • Visor meets ANSI Z80.3-2010 standard for non-prescription eyeglasses
  • Large and easy to reach switch activates the 3D injection-molded inner sun shield
  • Distortion-free shield blocks 99% of harmful UV rays
  • Forehead area of the outer shell is raised slightly to accommodate the internal sun shield, allowing the integrity of the GT-Air’s inner EPS liner to remain intact

Ventilation System:

  • Upper Air Intake Vent is positioned to maximize air volume into the helmet interior
  • Large upper intake vent positioned to maximize performance behind wind screens
  • Easy to operate large lower intake vent
  • Lower air intake/defroster vent reduces shield fogging and increases ventilation
  • The rear/neck vents allow for effective air exhaust
  • Breath guard and chin curtain included

Advanced Integrated Matrix (AIM):

  • High performance fiber materials are combined with elastic organic fibers to create a shell structure that is ultra-lightweight, rigid and resilient

Interior System:

  • 3-D Max-Dry center pad and multi-layered, polyurethane foam cheek pads
  • Chin curtain prevents wind entry and reduces noise
  • Cheek pads are replaceable or removable for maintenance
  • Eyeglass compatible interior
  • E.Q.R.S. (Emergency Quick-Release System) allows emergency medical personnel to easily remove the cheek pads from the helmet of a rider involved in an accident, in turn making the Shoei GT-Air more easily removable

Standard Chin-Strap Clip:

  • Neatly secures chin strap

CNS-1 Shield System:

  • The CNS-1, three-dimensionally curved shield is both wider and taller than the CX-1V it replaces
  • Includes Pinlock Anti-Fog Lens for more coverage of the CNS-1 shield
  • Dual-Ridge window bead increases contact with the shield to reduce wind noise
  • Scratch-resistant shield coating
  • 99.9% protection from harmful UV A&B rays

Safety Certification:

  • DOT-218

Note: Due to manufacturer restrictions, the GT-Air Helmet and other Shoei products can only be shipped to addresses within the United States

Shoei GT-Air Inertia Helmet (Size SM Only) 4.6 5 497 497
Great helmet in my limited experience of three other helmets My riding experience, Kawasaki Ninja 650, ZX-9r, Suzuki GSXR 600 and a 1000, BMW K1200RS and R1200RT. The RT is my main ride, hence I was looking more of a cruiser type helmet. So far, I have about 200 miles on this helmet. As a base of helmets: I have a Seven-Zero-Seven (large), Arai Corsair V (medium), and a Scorpion Exo 1100 (large). This is my baseline of helmets, so take it for what it's worth. The 707 is a good FIRST helmet for me. It is a large, and too big for safety for me. The Arai is a medium and was loose in the cheeks. I got new pads and it fits like a glove, but it whistled. It might just need new seals, but it is over seven years old. The Exo-1100 is a more of an oval elongated helmet. This does NOT fit me, especially in a large. But it has the integrated shield which I really LIKE! I got the SHOEI GT-AIR for the following priorities 1) safety, 2) fit, 3)integrated shade, 4th and 5th are a tie for noise and cost. Cost is somewhat a factor, especially at the $500 - $650 range can be an very expensive helmet. My head is worth it to me. It did take me some time to save this up for a while though. Hence, the GT-AIR. SAFETY: I THOUGHT this is same shell as the RF-1200 with SNELL rating, but I didn't really know. I was told the GT-AIR would have gotten the SNELL rating except for the integrated shade. I really want the shade. So I got this. FIT: The GT-AIR fits my (presuming) mostly round head very well. I am not even sure if I broke in the helmet yet. I've put about 200 miles on it so far. It is quite a tight fit. When I first put it on, I get equal pressure all around my head. At first, it is a lot of pressure, but I quickly get used to it, like within the first minute. It really does fit like a glove. I think this is the way it should fit. The Large is definitely too loose for me. I expect the pads to break in some more over time. It is more difficult to take off than even my Arai so far. NOISE: The GT-AIR does block a few more decibels of wind noise, but unfortunately, at the sacrifice of blocking other noises (such as engine and traffic). It's not so blocked that I can't hear, but it is definitely muffled compared to all the other helmets I have. The Corsair is probably muffles noises too. I am not sure if this is good or bad yet. I turn my SENA unit (I have these mounted in all my helmets) down on this helmet. It could be because the speakers are a little closer to my ears, or it could be because it blocks more noise. SHADE and FIELD OF VIEW: I'm disappointed in the GT-AIRs shade flips slider. I really like the EXO-1100 shade flip lever near the ears. The field of view is good. Not exceptional, I think my Exo has a slightly better field of view, but it could be because it is a large and this SHOEI is a medium. The GT-AIR field of view is better than my Arai. Remember, my Arai is quite a bit older though. Trying to move the slider, to me, always seems like I am trying to slide it the wrong way. Getting my gloved fingers on it's little bump of a slider is a bit of a learning experience still. VENTING: The venting, while clearing the face shield of fog is good, the head venting is not as good as my EXO. The EXO, especially in the summer, I can feel the air go on the top of my head. This SHOEI really seems to only clear the face shield fog at around 20 mph or more. WEIGHT: The SHOEI is probably a pound or so lighter than my EXO, but I am used to my EXO, so weight probably isn't that big a deal to me. PRICE: For the safety and features, and the sale price (close-out) from RevZilla, this was a good deal. I expect better prices as these get older and we get to the holiday season. Post a reply/question, hopefully, I can comment and answer. RIDE SAFE! November 2, 2015
Pro: Air Flow, Weight, Sun Visor Con: Price, Chin Strap After wearing Modular Helmets for approx. 10 yrs, this was a nice change. Very light and lots of air flow throw the top air scoop. Fit was also nice after being broken in, I have own this helmet for about 9 months. The down side to this helmet is the price, I would loved to have bought one with graphics but I could not see myself paying the additonal cost. The extra $100 plus was too much. Also, the Chin Strap will dig into my neck if snug. The helmet will also whistle depending on the angle of my head. But still the best airflow of all the helmets I've owned. November 24, 2015
I have to say, its a very good helmet Love the switch for the shades, it's very convenient. Very light weight. Provides wide vision. The design it's fire. November 23, 2015
Great Helmet, just get past that break-in period This is an exceptional helmet, all of the features are well thought out and designed, and they work! It's important to get one that fits though! I am a size small and when I first tried this on I tried a medium that was comfortable in store but rotated a bit too much on my head. I went with the small and felt general head pressure and claustrophobic for the next 10 hours of riding. It's all broken in now and it feels great! Those cheekpads will break in over time. As for the features: -The sunvisor is great and saves me the hassle of shield changes at night. Also the mech feels solid and low-profile so it wont break -The pinlock shield is awesome, no fog even on the coldest rainiest days, however the sunvisor will fog up -The chin curtain is great and stays in place solidly -This helmet vents a lot of air, but when sealed up it is nice and quiet (AKA the vents actually work unlike a lot of other helmets...) -Feels rock solid on a naked bike at highway speeds, doesn't buffet much at all Really great helmet overall, a huge step up from the cheaper stuff and well worth it. Also, if you need to replace liners etc...Shoei actually offers that stuff. November 21, 2015
Good helmet The older RF1100 used to have a toggle where you could slightly crack the windscreen. The GT Air has detents, but this feature is missing. I think the theory was that if you have the pinlock, you don't need to be able to defog the helmet. In practice, having the toggle to slightly crack it would still be useful, especially if you wear glasses. November 16, 2015
Great helmet overall I thought the look of this helmet was pretty slick so I went for it, I've used Shoei helmets exclusively for 12 years and have not had a problem, and this one lives up to the same standard. Great fit, great look. The only problem I had with this helmet is that the small pin in the visor for attaching the replacement visor shields was missing on the right side. Without it, there is a small hole in the visor that causes an unbearable whistle noise. So I will have to reach out to Revzilla or Shoei to see if I can get a replacement plastic pin just to fill the hole. November 9, 2015
Simply an awesome helmet I've used different helmet vendors over the years, and I keep coming back to Shoei. Everything simply works. The GT-AIR has been a nice upgrade over my RF-1000 that it replaced. It fits me just as well and has increased air flow. I love how easy it is to remove the shield for cleaning, and I can ride all day without any issue from the helmet. What else is there to say - great product, and I'd buy it again. October 26, 2015
Great helmet but I have found that the air flow isn't that much better than my previous helmet and I was expecting it to be way better being it is a GT-Air. Also on very cold rides (in the 30's) I am finding the interior face shield does fog up a little around the nasal area which is also a tad disappointing. I was expecting perfect and I have found that perfect is not for real even in a $500 helmet. October 26, 2015

Monte M: Hello. I'm not sure about the Quest as I've never owned one but I do own the rf1100 & 1200, which both fit a little bigger than the GT Air. The GT Air is very snug even though it's the same size as my other Shoei helmets. Hope this helps. Jul 5, 2014
