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 for the money The only issue I see with this helmet is the small slider rather than a larger release button i have seen on most other helmets to release the front of the helmet to raise it. September 22, 2014
The back light is such a safety feature Great product safe, stylish and light. A great overall value. September 22, 2014
second helmet Take it with a grain of salt as this is my second helmet I've ridden coming from a dissapointing hic IS modular. That said I love this thing all kinds +looks+feel++function+features+price 2 objections after about 2 weeks. -my friend easily broke a plastic vent cover thinking it lifted the modular face..(?) -the modular face started coming down without me touching it while walking. Upon inspection it looked like the holster screw was loosening over time ??!! That's safety so I had to shave a star for not having better. Longevity in mechanics.. Overall satisfied just take very good care of it. And pay attention to bolts. September 8, 2014
awesome for price Only issue is windshield scratched alil. Light is bright, operation is easy with glove on. October 6, 2014
Great features for the right price This is my first helmet for my first motorcycle. I picked my bike up 140 miles from home and rode it home in 85+ degree heat. With the vents open I had no issues with heat, wind or excessive noise. The internal sun shade is great for riding sunny days, and has the added benefit of allowing you to crack the visor open. I am planning on picking up the brake light module to operate the LED brake light on the back of the helmet. October 6, 2014
Great helmet This helmet is great bang for the buck. I love using the built in sun shade during the day and the built in LED light at night. September 23, 2014
Good 1st modular helmet. We bought 2 Gmax GM54s helmets and using the measurement chart recommendations we ended up exchanging both helmets for the next larger size. Living in a "helmet optional" state (PA) these are the 1st helmets that we have bought. Since we have been riding without helmets for so long it is difficult getting used to. The helmets seem to fit tight putting pressure on head and even seem heavy. However this may not be the helmet itself and could just be us not being used to wearing a helmet. The sun visor is difficult to slide, slide seems to stick. Love the design of a modular helmet. September 23, 2014
great value one of the best rated helmets for great price and free shipping September 22, 2014

Faran R: I already have a full face helmet and I wanted a modular for street riding and just get lazy at times with a face full.
After ready reviews from many different websites on sub $200 helmets this seemed to have received the most positive feed back.
Hopefully it doesn't disappoint. Gmax does seem to carry really comfortable helmets for the price.

Stephen N: Needed a good helmet on a budget. This helmet had amazing reviews and comes with great features. Jun 25, 2014
Kevin H: safety conscious older biker Jun 12, 2014
Roberto B: I Have the Non-Modular version of this helmet, and like the style and the rear light. The modular feature makes it easier to talk without removing the helmet. May 2, 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
Chris B: I went with this helmet because of the features and the price. I was originally looking at the regular 54s, but then I saw this styling and really liked it. Sep 8, 2013
