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.


  • 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)

Reviews on Modular helmet vs Bell. Also Hi Viz yellow for safety. Should be the same price as other colors though.
Philip D on Aug 26, 2016
The modular style, airvents (it gets 115 + in the summer in AZ), flip switch sun visor, bluetooth speaker pockets, and very importantly, the high visibility color!
Tammy P on May 29, 2016
Liked the vents and the brakelight
Jay A on Apr 15, 2016
Awesome helmet for the price! Modular, comfortable, plenty of venting, clear optics, eye-catching color, integrated sunshade, D-ring strap, and best of all: an integrated flashing red LED light in the back of the helmet. Brilliant! This thing is xlnt.

Based on rating given by revzilla, and the safety features

Bang for buck and Hi Viz for daily commute.
Daneen W on Mar 6, 2015
Hi Viz adds to safety and the price point is very attractive. No risk purchase. I want to love this helmet. Let's see what happens.

Looking for a hi viz modular. Have long oval head. Tried Shoie but noisy and not hi viz, only yellow. any suggestions?
Thomas K on Sep 10, 2014
BEST ANSWER: 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.
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.
A shopper on Nov 29, 2015
BEST ANSWER: Hello, no need to send you photos. I have three types of gloves, vented armored ballistic for summer, short leather for cooler months, and longer insulated and armored leather for winter months. With all three, I have no problem actuating the vents or lowering or raising the visor. Even the LED rear flashing light is easy to turn on or off withe gloves on. You biggest challenge will be to remember where the vents are as this helmet has many of them. This has been my best purchase in helmets for quite a while.
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.
Shawn L on Mar 29, 2015
BEST ANSWER: Hiviz and then some. The color is brilliant yellow green. My son gets all kinds of comments about losing their eyesight
Do the sizes seem to run true or small?
A shopper on Mar 10, 2015
BEST ANSWER: 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.
Can I wear eyeglasses and still use the sun visor?
A shopper on Dec 1, 2014
BEST ANSWER: 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!
What kind of chin strap system does the high-viz helmet have? Is it double d-ring or something else? Thanks!
A shopper on Oct 17, 2014
BEST ANSWER: 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!
