GMax GM78 Helmet - Solid 4.3 5 52 52
Great value! I've put about 400 miles on my bike since I got this helmet. I really like this helmet and it is an excellent value. I'm not exactly sure how someone is supposed to comment on the protection level unless it has saved their noggin and so far for me that hasn't been an issue (knock, knock, knock). This helmet looks great and has a bunch of do-dads. I really like the sun visor. If I was asked to provide any negative feedback, it would be that it is kinda loud. If I have the visor up with the shades down, there is a very loud whistle. If I shut the visor, it gets hot, but I'm in Texas, so it is asking a lot to not be hot. So far, I like this helmet.

Great bang for your buck Just got the helmet today and when I first opened the helmet bag all I could say was "wow". I was expecting some cheap helmet for the price of the GMAX GM78s, but is a very nice helmet. I couldn't decide between the matte black, white, or titanium but after seeing RevZilla's review on the titanium colored GM78s I was hooked. I do think the visor engagement tab feels a little cheap, but for sub-$110 it'll do just fine. I used the sizing chart and the helmet fit perfectly. Once it breaks in it will be even more comfortable. Not to mention that there was FREE SHIPPING and RevZilla PAYS the tax!! Plus RevZilla's legendary rated customer service I feel confident if I have any problems they will sort it out. Next thing I will be purchasing is the GMAX brake light wireless kit for the helmet. Did I mention I ordered the helmet Sunday evening and it came Wednesday Afternoon? Talk about fast shipping. I highly recommend this helmet. September 16, 2014
This helmet is worth the investment, but xoukd use some retweaking. This helmet is a great starter helmet. The drop down visor and multiple air paths enable comfort and plenty of air while riding. The downfall to those vents are an over abundance of noise. Also, the helmet runs fairly large. I typically wear a large and it felt significantly bigger. Some of the features are easily broken (sun visor clip broke second week in). Other than that, I still use this helmet for cruising and on nice summer days. September 15, 2014
Excellent entry level helmet! I still use and love this helmet. Fits great, it felt almost constricting at first and i considered returning it for a bigger size, but i gave it some time and i once it was completely broken in, I found it to be a perfect fit! I used the sizing chart and video on revzilla, so good job guys! I have the matte black one and I get a lot of compliments on how cool it looks, plus everyone like the flashing LED in the back as an added safety feature. A lot of people tell me it feels heavy for a helmet, but I have no issues with the weight. Although I do have a muscular build all around, including my traps, so that may be why it isn't an issue. airflow is great, its a tad loud, but great. I sweat pretty easily, so i only have a heat issue when i'm waiting at a light for too long, though, that can be said about almost every helmet out there. It does feel kind of cheap when compared to a $300 helmet, but not so cheap that it doesn't feel safe. great helmet for entry level riders for a great price! i would recommend this to a beginner and suggest upgrading when they get a faster bike!

like the quick release don't know why every helmet doesn't have a quick release. September 8, 2014
Stellar airflow and very intuitive design and features make this helmet a winner The GMax GM78 helmet is the best, most comfortable helmet I've owned to date. The exterior design is very aerodynamic and provides a minimal amount of drag when changing your POV, which is crucial. The airflow is absolutely top-notch, and completely adjustable via the numerous portals located in strategic positions all over the helmet, allowing you to control the flow as much or as little as you would like. The helmet also has a built-in light on the rear with three lighting modes: Solid, slow-flashing, and fast-flashing, which greatly add to your visibility when on the road in the early morning, at dusk, or well after dark. Due to the increased airflow, the noise level can get a little higher than helmets without better airflow, but that is to be expected. All in all, nothing negative to say about this helmet, whatsoever. September 2, 2014
I love it This is my first helmet and I love it. I have had off road helmets in the past but this is my first street helmet and it is perfect would recommend 10 out of 10 times September 1, 2014
Comfortable and great features, very loud. I bought this helmet to replace an aging 8 year-old Icon helmet. This was a lot cheaper but the features and reviews made me decide to get it. Bang for the buck is unbeatable and the helmet is well constructed overall. As of this review I've ridden 1,500 miles with this helmet over the course of 2 weeks. Pros: -Comfortable -Good Angle of View. (Glasses fit very well without being crushed!) -Helmet material breathes well, well ventilated -Interior Visor! -Very little rattling Cons: -Loud/Windy. The pressure from the wind ended up causing me severe pain on my ear drums (I have sensitive ears so this may just be me. I must wear ear plugs with this helmet if I go anymore than 30 miles). -Interior material is kind of scratchy/stiff but it may soften up with use. (only noticeable when putting helmet on/off) -No pull tab on the helmet strap. Not a big issue but a small thing that makes it a lot easier to separate the links, especially if you're wearing gloves.

RevZilla Store asked: Why did you choose this?
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
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

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
