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)

Excelent Helmet Great Visibility This is a must Buy, I just recently had a few close calls that made me want to go Hi VIS. I really Like this helmet so far have about 150 Hrs on it . it is a little noisy with all of the vents open. Love the Hybrid feature Not sure how I got by without it.. If your on the fence about going hi Vis just do it. Cars notice me now it is a definite change point. This is a very solid helmet and good price point.. September 16, 2015
Bang for the Buck This modular helmet offers tremendous value for the $. Ample vents, slide-down sun shield, quality cushioning, easy-to-use modular design, xlnt visibility w/ the hi-viz paint, and the LED flasher in the rear of the helmet is brilliant. For $170, this helmet offers ALL of the features of helmets costing well over $500. Awesome! August 24, 2015
Lots of features. I bought this helmet for my GF, and I love the light up bar on the back of the head. The modular style is very comfortable and another nice feature is the removable wind blocking fabric at the chin. October 5, 2015
Very pleased Purchased because of past experience with this brand. Very satisfied overall. September 21, 2015
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
Good helmet.great value! I bought this to replace my aging Arai full-face helmet. It is a little heavier than my old Arai, but makes up for it in every other way. I have great visibility and great airflow. It is a bit loud, but I think that is a trade-off for good airflow. In the Texas heat, airflow wins. I like the ability to take ear peices out...was especially helpful putting in headset. It has recessed ear holes, so there is plenty of room for speakers/headset.The built-in sun shield is awesome! Once you have one, you will never want another helmet without one. I would definitely buy it again. August 26, 2015

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
Answer this · Send to friends Good question? Yes (0) No (0)
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.

Shawn L asked: The picture displayed for the GMAX 54S Hi-Vis looks like the helmet is only a regular yellow color, is this helmet actually Hi-Vis? I am looking for a really bright reflective yellow. Mar 29, 2015

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

A shopper asked: Can I wear eyeglasses and still use the sun visor? Dec 1, 2014
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

A shopper asked: Can you show pictures from different angles, or a 3D view? I want to see the profile of the vents and sun visor lever, so I can judge ease of use with gloves. Nov 29, 2015
