GMax GM54S Derk Modular 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.

Features:

  • New inner flip tint sun lens
  • Inner flip shield is easily raised of lowered with a lever located on the exterior of the helmet
  • Distortion free clear single lens shield
  • New integrated multi-function red L.E.D rear light
  • Optional rear brake light kit available
  • 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. The added performance keeps you dry and comfortable
  • 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

Great helmet for the price. The fit is perfect and is quieter then my other helmets.ventilation is somewhat disappointing for summertime riding, but is warm in cooler rides. The rear light is a plus and provides good visibilty. June 30, 2014
Awesome Helmet This is a great helmet that I highly recommend to anybody looking for safety and value July 21, 2014
Super value My first modular helmet. I wanted to try a modular without investing a fortune and the Gmax 54s was an excellent choice. It is actually quieter than my Shoei RF1000 but does not vent quiet as well. Love the internal sun shade. Good fit and finish. I am very happy with my choice. June 30, 2014
A I tried several helmets from different brands. This helmet fit the best and was the most comfortable for me. Comfort was my first priority. June 9, 2014
Great Helmet Less than 36 hours after purchasing this helmet, It became clear that I would have to purchase another helmet, and, Without any second thought, the new helmet would be another GMax GM54S Modular Helmet, You may be asking why I would buy another one less than 36 hours purchasing the first one? Well, the first one made contact with the asphalt with my head inside it at 35-40 mph. Speaking from first hand knowledge as to how well this helmet protected my head, Not a scratch, bruise or bump on my head, not even a headache, Well Done Gmax! June 4, 2014
I like it Very good value for the $. Kind of noise on my fz1., But I am running it without the mesh shield under the chin to make better room for the boom mic on my Sena 10 bluetooth. Which by the way fits very well into this helmet May 26, 2014
Great helmet with high end features Love this purchase. I get asked about the helmet all the time. Especially about the light on the back. Great helmet with high end features. May 21, 2014
Can't beat for the price. Had to trade them in for one size up--felt like they ran slightly small. Put SENA blue tooth in them and they worked out great. My first modular helmet design I really have no complaints. May 19, 2014

Gary W: Like brand and apperance Mar 27, 2014
Andrew N: I picked this helmet because I had seen it in a shop where I live and had a chance to try it on and test out the modular features its has. The helmet feels very solid and provides good air flow when your riding. It also comes in an XS and that is very much appreciated as I have had a very hard time finding a helmet that will fit correctly and do what I want it to. Mar 24, 2014
brent b: I like the look of this one and it had much better reviews than the cheaper helmets I looked at as well as some of the more expensive ones. I had 200 dollars as my self inflicted limit. I wanted a bluetooth but it looks as though anything under 450 isn't worth buying as a single unit. Mar 22, 2014
Rhea s: This is a great helmet and I love it so much. Sep 24, 2013
