GMAX GM54S Modular Hi-Viz Helmet

The modular design 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 tint sun lens
  • Inner flip shield is easily raised or lowered with a lever located on the exterior of the helmet
  • Distortion free clear single lens shield
  • Integrated multi-function red L.E.D rear light
  • Optional rear brake light kit available (sold separately)
  • One hand easy to use chin bar push to open mechanism
  • Lightweight D.O.T approved thermo-plastic alloy shell
  • Excellent shield sealing reduces unwanted air and noise
  • GMAX "D.E.V.S" adjustable "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/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

GMAX GM54S Modular Hi-Vis Helmet 4.7 5 3 3
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
Lot of features for the money I love all the vents in this thing. The flashing red light on the back is great for nighttime riding. I love the sun visor that you can easily bring down even with gloves on. The front raises easily and comes back down with a simple pull. Easy to operate with gloves on. I love the high viz stuff. I've seen cars, pull up on side streets to turn onto the road and they slam on the brakes when they see me. September 1, 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.

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
