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 XL Only) 4.6 5 502 502
Great helmet # Great quality and function inner sun-visor # Top part ventilation - very good # Face ventilation - poor # Space for chicks and chin - bit tight December 27, 2015
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
Comfortable and 2 kinds of Cool Shoei makes a great helmet, we all know this. This one looks great, the graphics are pretty unique. It is light considering the materials it is made from. The visor feature works great, smooth action. The comfort is great and fits like other Shoei helmets size wise, except the race fit type helmets. I commute 45 miles in Raliegh NC, and the helmet is comfortable for the entire ride. Bottom line, it is a quality helmet, it is a Shoei and you get what you pay for. December 9, 2015
Awesome Love the helmet when I strap it on I feel safe and ready to rip!!! December 7, 2015
Awesome helmet I bought this to replace my old Shoei, which was I thought was a great helmet. The upgrades over the last few years including the removable padding, easier to use vents, anti-fog system and Sunscreen all make this helmet awesome. December 2, 2015
Surprisingly Quiet- Runs Narrow Many others reviewers have noted that this helmet seems to run a little small/ narrow. This is NO JOKE. Definitely be prepared to get a different pair of cheek pads in order to get the best/ comfortable fit. IMHO Shoei should offer different cheek pad size options when you order rather than making you spend an additional $50 after purchasing this high-end helmet. Also, because this is definitely a narrow helmet, you may even need to get a larger shell size than the fit guide measurements would indicate- I feel that although my measurement sits squarely within a small on the fit guide, the helmet is significantly narrower in the crown of the head than the guide would indicate. Just be careful and sure that you got the right size before taking off all the stickers and using the helmet. This is definitely a premium helmet at a premium price point. However, although everything is very well put together, some of the materials are not as premium as you would expect given the price or when compared to my other premium helmet at a similar price. The lining materials just aren't quite as supple- though they're still comfortable. I think what you're trading off for is the drop down visor, which is really well made and works really well, though I will say it tends to collect some moisture on it on colder mornings- it doesn't really fog, but larger drops of moisture do form and can obscure vision slightly. Ventilation of the head is fantastic- you get a lot of fresh air and it definitely keeps you cooler. However, I agree with some other reviewers that the shield seems to fog much much more than other helmets- using the PinLock insert is a MUST with this helmet, otherwise you won't be able to see due to fog on the visor, regardless of the outside temp. Finally, the noise level on this helmet is really great- rather quiet for such a sport helmet. Like others, I suspect the tight neck opening significantly helps with this. Unlike my other helmet, there is not much of a noise level difference with the vents open vs closed- it's equally quiet in either setup so I just keep them open all the time because I enjoy the fresh air. Overall, this is a quality helmet that may still be a bit overpriced, but will be the go-to helmet for the right rider. Just be careful about the fit. December 1, 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
