Best helmet you can buy This is the best helmet you can spend your money on. March 30, 2015
Bang For Your Buck I've gotten a lot of compliments on this helmet and it was so easy to install my sena bluetooth. The cheek pads already have a spot to put speakers. The LED light on the back is a great feature at night. People think I paid a minimum of $200 for the helmet. I'm impressed. March 27, 2015
visor is good strap is not quick release! for me that's a no go! also, buy 1 or 2 sizes bigger than your hear measurement. March 23, 2015
Great helmet I've had this helmet for 3 months now and I must say I'm not sorry I bought it. Great fit, very comfortable. The tinted inner visor is just dark enough without being too dark and works great. Ventilation is a bit too good for winter, but I can tell it will be fine in the summer. Fogs up a little, but when your're riding in 25 deg weather, it's pretty tough to keep from fogging up while in traffic. Once you get going though, no problems. Noise is average. My bike does not have a faring and I have no problems with the little wind noise I get. February 28, 2015
A little heavy but other than that it's perfect Love the LED on that back that can connect to brakes with a pretty cheap accessory April 13, 2015
Affordable Full Helmet All in all a fine helmet for the price. Noise, fit, built in sun visor, LED rear light were the selling points for me. I have only one complaint. With all the vents closed and visor down, there remains a swirl of air current I never had in my previous Shoei and HJC helmets. This may ensure a defrosted visor, but it also kept the face area chilly when I was at 50mph plus in 50 degree temperatures. January 29, 2015
Great features and price. I am an Australian and I bought this helmet for the great features - the internal sun visor and the rear brake light. You have to buy and install the brake light and transmitter, so this adds to the price, but in my view it's worth it. The helmet is still competitively priced compared to what you will get in the uncompetitive Australian helmet market. The padding is fine, but this is an entry level helmet and not much noise is blocked out. I regard that as a safety feature - no one wants to have an accident because they can't hear what's going on around them. A real attempt has been made to ensure air flow around the head by GMax. That's really appreciated by those who ride under the hot Australian sun. A note for Australian buyers; since this helmet comes from the US, it will not have the essential Australian Standard 1698 sticker and internal label and it therefore will not comply with the law. You will therefore have to, er, find a way to apply a sticker and sew the internal label neatly. Fortunately, the padding comes out easily and the label can be sewn in without trouble. January 12, 2015
Very pleasantly suprised I got a great deal with this helmet. Not only does it have an internal, easy-to-deploy sun visor, but the back lights up (LED) at the touch of a button for a little extra safety! No whistling noises like the lame AGV Horizon I was wearing previously, and no other downsides to note. While I have not been using this helmet for long yet, it is definitely recommended.

Tyler B: It has a wicked cool light on the back. Apr 17, 2015
Carlos C: The lights on the back, the nice look, the sun visor...Nice Apr 10, 2015
Brandon B: Good reviews. Supposedly good airflow. Flip down visor is clutch. Apr 9, 2015
Odonis S: Love anything black especially matte black Mar 6, 2015
Jose C: Mainly for cause of the affordability of it. Its a very nice sleek cool looking helmet I was looking for and with the LED lights in the back just made it the deal breaker over most helmets on the site besides pricing. I'm not a big fan of where the drop down visor mechanism is placed, its placed pretty poorly for the looks of the helmet and should have been placed unseen but easily accessible for the rider to find. but over all its a great helmet. Feb 3, 2015
Jeremy L: Very Affordable option, best looking white helmet for the price. Drop down sun visor and you guys sell replacement visors and tinted ones. Feb 2, 2015
Jose R: Price Dec 30, 2014
Jesse L: Skeptical really. reviews are mixed. Anthonys reviews are sometimes very nonjudgmental making it tough to gauge the quality of this helmet. Dec 29, 2014
M C: Because of your great review, of course! Dec 24, 2014
Miguel D: I was looking for style, bang for the buck, protection, and features. I really feel that this is an amazing intro helmet. everyone else really likes it ;) Dec 2, 2014
Roy M: Price, style, features and good reviews Nov 26, 2014

Joseph P: it has good features for a good price Oct 13, 2014
Michael K: Most bang for your buck! The sun visor was important in my purchase desicion and i liked the LED light in the back of the helmet to increase visability. Oct 9, 2014
Daniel F: Available in a 3X, plus I liked the features offered. Such as... the internal sun shield. It had other good reviews, so decided to give it a try, plus the price was right... Oct 6, 2014
james B: Because it was monetarily economical and the helmet hat an interior secondary sun visor; as well as an anti fog visor. The helmet had a visually appealing look; sleek yet highly functional. Oct 5, 2014
James L P: I'm a novice and am relying on all the great reviews. Oct 2, 2014
Krystopher R: Great price for the amount of features. One of the only helmets on the market with LED light on the back that can also be wirelessly connected to your bike's brake light. All three available colors go with anything. The black looks aggressive, the white looks clean, and the titanium is the perfect medium. Because of RevZilla's legendary customer service, free shipping on orders over $39.99, and not having to add tax to those pricey orders, I will definitely be shopping at RevZilla again. Sep 14, 2014
G U: Great first helmet for my wife she loves the helmet and the light feature for added safety in the back of the helmet Sep 11, 2014
James W: Quality of helmet for the money. Inside sun visor and better cooling than most other helmets Aug 26, 2014
Travis E: Met my requirements of clean solid color, built in shades, and had tech that i thought is worth trying...(hi viz 3rd led light that can be synced with brake lights) Aug 13, 2014
Peggy V: Flip down internal sun visor with clear shield for day and night riding, lots of adjustable venting for summer riding. white for visibility. I ride an 80 CB750 in the upright, relaxed position. also the red light in the rear of the helmet. and the comfort, i tried one on in a store and it was a great fit. May 6, 2014
tim b: Wanted something that looked different Apr 3, 2014
William S: I wanted a helmet for my girlfriend to wear while riding with me. Safety, comfort and value were priorities. Feb 22, 2014
truong n: Great bang for your buck helmet. Exceptional ventilation. I can definitely say it runs 1 size bigger for me but it does fit nice. The helmet itself just makes my head look big. Dec 2, 2013
James C: Most bang for the buck, right in my price range, Sun visor and light on back of helmet Oct 10, 2013

David G asked: My head measures 22 & a 1/4" should I go a size up from small to a medium? Also I really like the Gmax gm54s model but there seems to be a lot of negative stigmatism surrounding modular helmets are they safe? I plan on purchasing this tomorrow morning. Nov 18, 2014

Jim H: I found the size to be pretty accurate compared to the size chart. The GMax line is really a good secure helmet.

I also would not be too terribly concerned about modular helmets. I also have a Schuberth C3 Pro and love it, but it's quite different than just about every other modular on the market.

Kent W: I was also on a size break between XS and S - but have a pretty round head and went with the S (21.75" diameter). Fits me great and is comfortable, but not loose.

Can't speculate as to modular, i'm sure there are pages on motorcycling forums that debate that very issue.

A shopper asked: Does this come with a smoke shield Apr 27, 2013
Answer this · Send to friends Good question? Yes (0) No (0)
RevZilla: This helmet does not come with a smoke faceshield. It includes a drop-down sunvisor, which eliminates the need to change faceshields. May 2, 2013
Reply to RevZilla Good answer? Yes (2) No (0)
jairjair26: No, it comes with a clear pinlock insert only. The smoke insert is available for around $35, when ordering make sure you buy the SAI max vision version. On another note, the dark smoke is not very dark so if you are thinking about the light smoke you may want to order the dark instead. Apr 27, 2013

A shopper asked: I've been around motorcycles for about two years now and just picked up my brand new r6. Do any of you think that this helmet would be a good upgrade? Also, I'm torn between getting a Medium or a Large. I normally wear a 7 3/8 hat size but sometimes wear a 7 1/2 as well. Is the sizing pretty accurate to the size chart?? Jan 7, 2015
Answer this · Send to friends Good question? Yes (0) No (0)
Kent W: For me the sizing is pretty accurate. I used the inch measurement from GMAX and it fits well. I do have a fairly wide head (head is more round shape than rectangular), which is why i went with this helmet. It is comfortable even on long rides. Jan 12, 2015
Reply to Kent Good answer? Yes (0) No (0)
Sarah L: I used the sizing chart and it was accurate for me. Plus Revzilla does one free return if you need to size up or down. Jan 7, 2015

Jason S asked: Aside from not being modular, how does this helmet differ (if at all) from the Gmax GM54S? I like the GM54S but I am not a huge fan of where the release for the chin bar is and don't necessarily need a modular helmet. Aug 6, 2014
Answer this · Send to friends Good question? Yes (0) No (0)
Kent W: Haven't tried the GM54s, but this helmet is comfortable and would probably be lighter than the modular since it has a less complex design. Aug 13, 2014
