What's this?

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.

Features:

  • 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)

GMAX GM54S Hi-Viz Helmet 4.4 5 188 188
You get what you pay for It is what it is. Its a loud, mediocre helmet. In the month I have had it I have already had the two front vent covers fall off. The Wind noise is awful at speeds above 35, and even with all the v vents open I sweat like a pig. That being said, for the price, considering it is a modular helmet with integral sunshade and rear light, its a trade off. The modular chin guard is great, super easy to get the helmet on and off and nice to cool off/talk at stop lights. The red flasher is helpful as well at night, as well as the neon yellow actually working very well. Apart from the sweat, the helmet is very comfortable on my head. I never feel constricted or heavy. Granted Im a strong and large guy so its not too burdensome to wear it. All in all, I will not be buying this brand again for the reason of air flow and noise level. I would much rather have a quieter helmet with a cooler head than a modular one. For a cheap first helmet it definitely did the job I expected, but next time Im going to go the extra $100 and get something better July 23, 2016
Disappointed We bought three of these helmets (one for me, one for my hubby and one for my 17yo daughter). I love all the features this helmet has but the drawbacks are significant. The helmet is very heavy (4.5 pounds) resulting in a sore neck every time I wear it for distance rides. Holding my head up in windy conditions is a chore. I've only had mine for a couple months and the two plastic pieces that slide the sun visor up and down blew off while going down the road. I have a fairly narrow face but the cheek pads squeeze so tightly that my upper jaw is in misery after a couple hours. A larger size may fix that problem but then the rest of the helmet would be too big. My husband actually has dents in his head from the weight of the helmet after a day of riding. My daughter hasn't worn hers much. Hopefully hers will be better. We've already replaced mine and my husband's with something else. July 19, 2016
helmet is all that Revzilla says that it is. I took the Gmax gm54s out for its first spin this weekend. The fit felt very secure and comfortably snug. I like the ease of operating both visors. The Sun Shade visor is great with the only exception that I find that it distorts my vision slightly with my prescription glasses. I will probably restrict my use of that only to those times when the sun is in my face. I find that the noise level is pretty quiet and airflow seems good. It is really nice to put on a helmut with a pristine visor. Guess that will not last for ever but was not overlooked or unappreciated. Color is great: almost a rock solid match for the moto guzzi metallic grey. Very pleased in Virginia July 19, 2016
Great product for its price! I ordered this helmet for four reasons: it was a modular helmet, it was available in Hi Viz yellow, it promised to have good ventilation, and because of the rear light. The helmet did not disappoint. The modular system works as advertised, and it has all metal mechanism, which is safe. The latch to open took me some getting used to, I wish it was a little bigger and under the chin like a Schuberth, but beggars can't be choosers. The Hi Viz yellow does not disappoint, it is truly a high visibility shade of yellow, not the canary yellow you see in pictures. It stands out quite well during the day and night. Ventilation is very good, there are loads of options on vents to close and open, and I usually ride with all vents open because here in Virginia it's pretty humid. WIth all vents open I get no fog on the inside visor while moving, my prior helmet, a Joe Rocket RKT Prime got lots of fog inside. Hige improvement here. The rear light is excellent. I end up riding at night a lot because of work, and adding that extra light point up behind my head is one extra layer of passive safety to help me be seen. I decided not to splurge for the available brake connection because the light is not brake-light bright, but for an extra light point it is good. Fit is a little tight, I bought the large size, same as my other helmets, but I should have ordered extra large. I did not return to get a different size because I needed the helmet now (my previous helmet cracked when it fell in the garage), so I just ordered the extra large liner and different size cheek pads. With the new liner and pads the helmet fits great. When it gets cold I wear a Klim balaclava and even with the balaclava it fits well. My two biggest gripes with the helmet are the cheap build quality and the way prescription glasses fit with the cheek pads. The build quality could be a bit better, all the plastic bits on the vents are slightly flimsy and I can see I will have to be careful to keep them from breaking. Yes, it's a sub 200 dollar helmet, but even at this price point I think the plastic should have a better fit. Prescription glasses tend to ride up on the helmet while riding because the cheek pads force them upward. The narrower pads I bought for helmet fitment helped a whole lot, but once in a while during a ride I have to push my glasses down. I wish there was a channel contoured into the cheek pads to prevent glasses from doing that, I am thinking of modifying my cheek pads to create such a channel. Other than that the helmet is great, for the price I don't think you can find a better modular helmet. May 18, 2016
my first modular is a success! coming from a 3/4 helmet, I was concerned about vision and feeling closed in. Every full face helmet I tried on previously made me feel like I was in a prison. I liked the concept of modular but knew I wouldn't be riding down the highway with it open so I didn't know how this would all come together. I "chatted" with a Revzilla rep (I think it was Phil) and he discussed the helmet with me even down to sizing...He didn't guide me wrong. I have had the helmet a little less than a month and after about 800 miles, I know I made a good choice. The only issue is I ran into rain a few days ago and the shield fogged up immediately. Hopefully the dual lense shield will remedy that issue. Other than that it has been a great product for me so far. May 24, 2016
This helmet is very comfortable and the cheek pads feel great. Peripheral vision is really good. This is my first full-face helmet, so I have no frame of reference. Having said that, I love the fit of the GMax GM54s. I haven't had the chance to use it in hot weather, but the ventilation seems very good. And the wind noise level in not bad at all. The built in sun-shade is very handy as well. I have the flat black. My only complaint would be how easily the finish scuffed after my helmet slipped out of my hand onto the pavement while taking it of the helmet lock. Overall, I am extremely happy with my purchase.

Wish I'd bought this as my first helmet I was looking for an upgrade to my Bell Star helmet, specifically a modular style. This one fit the bill in several areas. I love not having to purchase a tinted visor as the drop down sun visor built in works nicely! However, having a prominent nose, the sun visor touches it slightly. Not a deal breaker, just a heads up to anyone with a gargantuan nose. The wind noise is noticeably greater than my previous helmet, although the aerodynamics of the GMAX are a HUGE improvement. Additionally, looking over my shoulder doesn't send airflow from under the helmet, causing misalignment of my glasses. This was a problem with my Bell. Field of vision is great! Nothing negative to say about the visor! If you're on a budget and looking for a modular with a lot of extras, this is it! I recommend earplugs at highway speeds, its tolerable for in town riding.

A MUST Buy!! I have had countless helmets over the years but this one ices the cake. It feels just better on my head. I can see more to the sides that any other helmet and the brake light with built in sun visor is just icing to the cake! Buy this one, you won't be disappointed! April 5, 2016
