GMAX GM78 Helmet - Solid 4.2 5 29 29
Great Helmet for the Price I will have more to say once I've worn it through an entire season, but I've had GMax helmets in the past, and for the price, I think this is a great helmet. I've never crashed, so I can't say how protective they are, but they're DOT certified. The only complaint I have is that the mechanism for sliding the internal, tinted sun visor up and down is a bit rough. While the slider is relatively easy to find with gloves on, It takes a fair amount of pressure to engage and disengage. But the tint is dark enough, it won't fog even if I try, and very importantly in my mind, it comes down far enough to block most bright reflections that come UP from chrome and gauges. I did a lot of research and had it narrowed down (for my price range) between this GMax GM78, the HJC IS-16, the Shark Vision-R and the Lazer Kestrel Z-Line Lumino. For the price, I went with this one as the best bang for the buck. Time will tell, but my other GMax helmets (plain jane, no internal sun visors) have all worked out well. I was replacing mine only because it's over four years old; otherwise I was happy with it. I look forward to another 4+ years with this helmet. March 24, 2014
Excellent helmet! I bought this helmet because of the good looks and the light on the back. I have since bought two brake light kits for my scooter, and ducati, and I am far from dissapointed! This turned out to be a cheap helmet that I now use more than my older shoei. My one complaint is that the finish did rub off on one of the corners from being in my scooter seat, but I should have kept it in the case anyway. March 17, 2014
Good first timer helmet Good balance of cost and features for a beginning rider while still having a comfortable fit and style. February 10, 2014
All bells and whistles It may not be Snell rated, but I'm convinced the features will prevent some situations where a top of the line helmet will be needed. An internal sun visor slides into place with ease for when you turn the corner and become blinded at dawn. The light on the back of the helmet (can also flash) gives motorists another point of visibility. All in all, this helmet is of great value. January 20, 2014
great price. i got the helmet and had to try it out, so I went out and it was pretty cool at first. but like 30 minutes later a sharp pain on the top of my head hurt so bad. worst pain ever. will not buy another one. December 28, 2013
Received damaged, size chart was off. I have no doubt the GMAX GM78 isn't a good helmet. It's just receiving one that actually is manufactured properly. I ordered this helmet twice, once the size was not true to the chart and the second helmet came with a broken sun visor. I really wish that wasn't the case because the helmet has a lot of cool features. I don't know what GMAX is doing in their shipping process, but it seems a bit careless. Revzilla on the other hand has been awesome with my returns and offers outstanding customer service, so that's worth some salt I guess. November 27, 2013
Wanted the added brake light, but now I never use it! I bought this for three reasons, the rear light safety feature, the built in tinted lens, and the extreme value for a helmet that has those things and more. After 3 months of owning this and riding almost everyday, I have only accidentally used the rear light when my kid turned it on without me knowing (I don't own the wireless module - yet). My favorite feature is the built in tint lens. I also have the "bubble" that others complain about but its a small warp that comes from the mechanism that moves the lens up and down and by now, I have to look for it to notice it. Pros: comfortable, amazing vents, pockets for Bluetooth speakers (I made my own for the cost of a Jackson!), quiet, well made. Cons: not a lightweight, does fog, larger than normal shape.

Just two complaints. Good bang for the buck if you ask me. I like the light on the back as well as the vents. It has the same noise level as my previous CJ-16 helmet from HJC. My main complaints are about the visor vent which is loose and always falls to the open position instead of locking in the off/on position. Second the 'chin gaurd'(?) doesn't completely block all the air that would otherwise rush into the helmet. I often find myself with a constant rush of air up inside the helmet with lots of particulates that get in my eyes... Final comments are the vertical field of view is much smaller than my M size HJC helmet. This Gmax is an S for reference. Also the sun visor is badass and convenient except I find myself without sunglasses when I'm off the bike. November 9, 2013

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)
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

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
