GMax GM78 Helmet - Solid 4.4 5 90 90
Great entry-level helmet. This is my first helmet, new rider, put about 350 miles in with it. I wear eyeglasses with this helmet with no issues. The drop-down sun visor doesn't hit anything and it's a great feature. It does feel a bit flimsy but it's been solid thus far. Airflow seems great, I've been plenty cool even on 90+ degree days. With all the vents open, at 50+mph it is pretty loud. I use plug-style earbuds and that helps a lot. A couple times I've worn it for 2+ hours and I start to feel pressure on a couple parts of my head. Perhaps that's true of any full-face. Fixed by taking a short break. Overall I'm very happy with this helmet for the price. August 31, 2015
Overall, great helmet! I've had the helmet for about 2 weeks and i am loving it. I dont have any other helmet to compare too, but the main concern with me is that the air ventilation is not the greatest. This could be normal compar3d to other helmets, but to me it needs a little more air ventilation. The internal sun visor and red light are perfect for driving in the sun, and being more visble at night. Great buy, recommend to everyone. August 24, 2015
Good budget helmet This helmet does fit true to size. It is obviously heavier and louder than your higher end helmets, but compared to lower end cost helmets it is lighter and definitely quieter. There are a lot of vents and the internal visor is exceptional. The LED light on the back is a really neat feature for an entry helmet. The finish is perfect with no blemishes and the foam is very comfortable. August 3, 2015
Broke before use I liked the features of this helmet and it seamed pretty sturdy, but the sun visor mechanism broke before I got it out of the bag. July 23, 2015
Love this helmet!! Everything about this helmet is awesome I'm glad I picked this one August 31, 2015
Great Helmet I have had this helmet for over a year now. Although I have never fallen or been in a crash (so I can't comment about how it holds up in that aspect), it feels pretty durable. The visor inside is great for sunny days without needing to carry an extra visor and switch them in and out. There is also a light on the back that I hear you can sync to your breaks. I haven't bothered to do this, and never use it. July 14, 2015
if you are thinking of getting this Helmet, you wont be diappointed I was finally able to convince my wife she needed a full face helmet. She came to the Revzilla web site as we have purchased from them before. She found a helmet that she liked the style of and we followed the instructions for sizing and bought according to them. The helmet fits like it is suppose to, nice and snug and she is well pleased. June 25, 2015
Well priced. Comfortable. Versatile. As a new rider, with not much cash to put in to the most expensive gear, I've found this helmet to be just as promised and much more. Lots of vent control for varying climate. Easy to use drop down sun visor is smooth and convenient (one of my favorite features). The fit is a bit more snug than I would have liked, but granted has gotten better over time. All in all, I've been very pleased with it. June 1, 2015

RevZilla Store asked: Why did you choose this?
kirk h: read a lotof reviews sounds like a good helmet for the price,needed a full faced helmet for winter,Im in Nor Cal and its freezin balls up here rite now Nov 25, 2015
Kenneth M: Good experience with GMax brand in the past: very decently-priced, with excellent features. This helmet is leaps-and-bounds better than the old GMax model (which i LIKED a lot, even though it seemed somewhat unrefined in some respects). I was very surprised at how upscale this model now feels compared to the previous one. VERY happy with this purchase (so's my wife--we each have one). Nov 5, 2015
Michael C: I like the style and the reviews. I like the dual visors, that was really the big seller. Price is decent too. Jul 11, 2015
Donald B: Seems like a good deal and I liked the features on the helmet Jun 26, 2015
Scott B: for the sun visor and led light May 29, 2015
Siddhartha R: The choice was based on reviews and features of the helmet. Reasonable price, and the built-in features like the LED light, additional vents, and the visor. May 3, 2015
Auguste G: Inexpensive but excellent value for its price. Hoping it will be a good starter helmet. Apr 28, 2015
Bryan S: I need a passenger helmet, I had bought this as my first helmet but didnt like the quality of the materials much but hey, it's at a great price though. When it came time to get the passenger helmet I went straight to this, mainly for all the ventilations it has, the drop down tinted visor and the LED flashing light on the back. The light is my favorite feature as it help people see us when riding. Apr 28, 2015
Aaron J: I chose this helmet one for the price and one for the amount of vents. Im usually a really hot headed person and the amount of cooling options of this helmet seems to have fit my needs. Apr 27, 2015
Robert M: Drop down sunshade, and LED kit is just trick. Lots of great reviews as well makes it a great bang for the buck. I was going to go with the Bell DLX because of the shield, but too many complaints about wind noise through the side cover and no chin curtain. Apr 25, 2015
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
Daniel M: love the the blinking lights in the back, will be good for night riding, and has plenty of intake and has the inside sun visor Nov 12, 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
Answer this · Send to friends Good question? Yes (0) No (0)
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

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
Reply to Sarah Good answer? 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

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
