GMAX GM54S Modular Hi-Vis Helmet

The modular design of the GMax GM54 allows the flip-jaw to rotate further back on the crown of the helmet. The further rotation of the flip-jaw not only increases the user's line-of-sight when in the raised position, but it also lessens the user's fatigue by maintaining an even distribution of weight across the helmet.


  • Inner flip sun shield is easily raised of lowered with a lever located on the exterior of the helmet
  • Distortion-free clear single lens face shield
  • Integrated multi-function red LED rear light
  • One hand, easy to use chin bar push-to-open mechanism
  • Lightweight thermo-plastic alloy shell
  • Excellent shield sealing reduces unwanted air and noise
  • D.E.V.S Dual Exhaust Venting System top, side, and rear venting reduces fogging and sweating by allowing hot air to escape from the mouth area and top of head
  • Adjustable chin vent directs air upward across the inside of the shield to help reduce or eliminate fogging
  • Large eye port for improved range of vision
  • Coolmax comfort liner and cheek pads move the moisture away from your body and the fabric dries quickly
  • Removable and washable interior and adjustable cheek pads allow for more comfortable sizing
  • Deluxe ear pockets for better fit and comfort
  • Built in speaker pockets for communication systems
  • Soft padded chin strap
  • Painted shell with high quality clear coat finish
  • Soft helmet bag included
  • Optional rear brake light kit (sold separately)

love this helmet ! very comfortable, not too heavy, sun visor works excellent, no fog ups , lots of cool features, very adjustable. I'm happy and would buy again! Super hi-vis for safety ! July 27, 2015
Nice helmet My previous bike had a windscreen and I wore an open helmet. This did not work so well on my new Ducati with no wind protection. This helmet is amazing! July 20, 2015
Great helmet at a great price. Had my doubts about this helmet because it was so inexpensive, but it has turned out to be a great helmet. This helmet is a slightly heavier then my old Scorpion Exo, however it some how feels lighter while wearing it. The sizing chart is dead on accurate, and if you have a little wider face this helmet will fit you very well. TLDR; Don't let the low price scare you, this is a great helmet. July 13, 2015
Hi Viz Gmax to supplement HiVis jacket My success with my 3 year old "white- 54S" Gmax, which I use daily and is outfitted with the SENA 10 communicator, prompted me to purchase this identical model in Hi-Vis, to supplement my Hi-Vis jacket. Air flow in mid-90's keeps my head dry (same as the older white model), providing you are riding at 30+ MPH. Others mentioned sizing to be a bit larger. I wear a 7-1/4 hat, and my original white flip-up 54S helmet was a medium, so I replaced with the same size. Fits a bit snug like it should, same as the older "white" model. Note: I also own a 3/4 GMax helmet in a large and it is a bit too loose to be considered "safe and secure"- I can rotate it on my head. Also, the full face flip-up 54S helmet, with numerous air vents, does a superior job of keeping my head cool and dry, even at 95 degree weather. In comparable hot weather, my head is saturated after riding with my white 3/4 helmet for only 20 minutes, which fits substantially looser! If you want to be seen by other riders, this HiVis helmet does the job! June 20, 2015
Great helmet----bright green - visibility saves lives I own two Gmaxx 54S helmets, and I am very satisfied with them. April 2, 2015
Inexpensive yet quiet and feature rich. My other helmet is a Shark Evoline 3 and I think I will like this helmet better. I have a very round head so finding a helmet that fits is very challenging. The padding on the GMAX GM54 is nicely thick and so compresses for a comfortable fit. I came in at the bottom of the XL range and it felt slightly large, but the fit seems right when I move it around to test. It has a lot accessories available on line and I may try the Large cheekpads when it is time to replace them. Yeah, I plan to keep it quite a while. The noise level is a significantly lower than with my Evo 3. I can almost ride it without ear plugs and adding earplugs makes it almost quiet. In comparison my prior 2 helmets had lots of wind and road noise. I have a FDR 1300 sport touring bike and the GM54 is actually quieter when I lower my head a little compared to a raised chin position. Reverse from my Evo 3. When I raise the windshield all the way at 50 the noise level is acceptable without ear plugs. The GM54 has lots of vents but the seal on them when closed is not that great. I did my test ride at 39-44 degree weather and with the windshield down had a cold spot on the top front of my head. With the windshield up all the way I get a little buffeting on the back of my helmet but this is less noticeable on the GMAX. On the other hand I did get cold spots on the top back of my head. I really look forward to riding with it in summer. The vent covers do feel a bit flimsy and and ill fitting. I can see putting tape over them if I were to ride a lot in really cold weather. I try to ride only above 40 so not a major reason to do so. The chin bar mechanism seems a little stiff right now but I think it will break in. Same with the Top Gun visor slide. The chin curtain hits your chin when you lower the chin bar but I find it acceptable and it seems to do a good job keeping wind off my chin. The Chin bar feels a bit heavy when I turn my head but the helmet does not seem to catch much wind and twist. I feel weight, not push and the double pane windshield I have probably adds an ounce or two. My Evo 3 lightly catches the wind when I turn my head. Right now my helmet is a bit stiff in operation but I expect that to wear in. I may try silicone spray but not yet. I can close the chin bar and face shield with one hand - nice since on the Evo 3 you have to use 2 hands. The face shield has a little tab on the lower left which is a good position for working with the left hand. Several strong detentes let you step the shield up. Also, the chin vent has 3 positions - down = fully open, closed, and up=slightly open and slightly pushing the face shield up for a very fine crack opening. Not sure how effective that last is but will find out in spring. The Top Gun sun shield is on a continuous friction slide, This is much nicer than the click all the way up/click all he way down on other helmets since I can set it at different levels - from touching the tip of my nose to just a little down to reduce street light glare. It is very dark by my standards. which is problematic for me since I like to drop it 1/4 of the way at night and tilt my head to reduce glare from oncoming cars. However, it is so dark that seeing the road and markings is hard. I ordered the Amber shield but the wrong one got shipped. I'm impressed with Revzilla customer service in making it right. Anyway, I like the sun visor operation but will need to explore color options. Overall, while the vents feel cheap the helmet is meeting my expectations and hopes. It is feature rich and there are lots of add-ons like extra cheek pads, other visors and colors, etc. and it is inexpensive on Revzilla. I just need to remember to use the flasher feature at night. :) December 29, 2014
Great First impression I honestly never had a high reguard for Gmax products but after weighing all the option this helmet found it way at the top of the heap so I thought I'd give it a try. I have to say that this helmet is much nicer than I expected. The thing is feature packed, light, comes in high vis and is super affordable. Really happy with the purchase! December 15, 2014
Great Helmet for the price Overall the helmet offers you the features and protection you need. Very comfortable, the liner is superb, some of the air vents seem a little bit too weak but time will tell how they hold up. My main problem is the chin guard that is included. Idea is great but implementation is bad. When closing the lowering the chin bar, the guard will get stuck on your chin or scratch your face due the chin guard plastic collapsing against your cheeks when this happens. I think if they added 2 more strap points to the guard this wouldn't happen, I actually just removed it because it was a nightmare to use if you truly want to use this helmet in a modular fashion. Noise levels are good to excellent and the light feature is really nice on those night rides October 6, 2014

thomas k asked: Looking for a hi viz modular. Have long oval head. Tried Shoie but noisy and not hi viz, only yellow. any suggestions? Sep 10, 2014

Kevin N: I tried on the Shoei and it is certainly well made but it's also over $600.
I have used this GMAX for a few months now and love it. It's very visible, I watched a friend wear it while on my scooter.
The modular feature is great on hot days. Of course when traffic gets busy I close the helmet to get the full face safety benefit.
Sun visor also a great feature. Helmet can be a bit noisy but you can close several vents to get quieter ride but noise hasn't been a bother for me.
I ride at 4:30 AM so the flashing light in back adds some extra safety when it's dark.
So thoroughly pleased with Gmax so far.

Michael B: Love this helmet! The hi vis color is just as stated VERY High Visibility. The modular function is right up there with ones costing considerably more. Great value and bang for buck! The design IMHO, is far beyond the designs of others in its class! I also love the added LED light on the rear of the helmet! Again...adding to hi vis features of this helmet.

Noise to me was always lowest priority....I like hearing the wind fly by my helmet as it passes my mini windscreen. Plus, when speaking to other riders or receiving a call via my Scala Rider, folks on the other end tell me they hear absolutely no wind noise.

A shopper asked: Do the sizes seem to run true or small? Mar 10, 2015
Answer this · Send to friends Good question? Yes (0) No (0)
David M: I would say that they run true to size. I used a cloth tape and went by my true measurement size. It is always better to try it in person if possible. Every head shape is different. Two people may have the same measurement but any helmet will fit tight in spots on one and lose in those same spots on the other. As soon as you get it try in on for about 20 to 30 min. If it is to small your head will be tingling in those high pressure areas. Mar 10, 2015

Answer this · Send to friends Good question? Yes (0) No (0)
Michael B: Yes, I wear glasses and the sun visor goes right over them. I had the same concern before purchase and glad I made this choice. This is the best helmet I have bought! Dec 2, 2014

A shopper asked: What kind of chin strap system does the high-viz helmet have? Is it double d-ring or something else? Thanks! Oct 17, 2014
Answer this · Send to friends Good question? Yes (0) No (0)
Michael B: The chin strap is a double D with a snap on the end of the strap that snaps onto itself close to the DD to eliminate the wind from flapping it around. This is the best helmet I have purchased! Oct 18, 2014
