I love this helmet

by - verified purchaser
Lot's of vents for a more comfortable ride and are easy to open and close while riding. Good vision and the ear pockets are sweet, no more hot ears!!! The face piece locks solid and is easy to lift and the flashing rear mounted LED is a real bonus. Superb value for the money.

Helmet is comfortable. Visibility out clear and tinted visor is excellent. Great ventilation. I wear glasses and helmet was easy to place on and remove without removing my glasses. Wanted a product that would provide excellent protection for all 4 of my family members and I got it.

GMax GM54S Solid Helmet Review

by - verified purchaser
Helmet fits and feels good but the clear outer lens is wavy and distorted. Contact customer care and they promptly sent a new lens. The new lens is just as bad if not worse than the first one was. If the lenses are this bad, I don't trust the rest of it, I am going to send it back.

GMax GM54S Solid Review

by - verified purchaser
This helmet is a replacement for my previous GMax 54S. That one got dropped, Overall, though, it has been a good modular helmet. Replacing the face shield is as easy as any other helmet I've had. It is reasonably priced, and yet has good quality components. The light on the back of the helmet is a bit of a gimmick, and I never use it. Sometimes the air vents whistle slightly when open, but it's not bothersome. Obviously, I liked the original enough to buy another one.

purchased this for my daughter, over all is a good helmet. Fits her good, she likes the internal sunglasses, i liked the light in the back but after using it one time it stopped working. Plan on taking a look and see if its just a battery, besides that its a good helmet for the price.

Had A Good OOPS

by - verified purchaser
When my helmet arrived I noticed the box was wrong and upon opening it the box was correct and they had sent a GMax 54 instead of the GMax 67 I ordered. I loved the look and feel so I called Jafrum and after explaining the error I explained that I wanted to keep the GMax 54. It was no problem to pay the difference AND my honesty got me a VERY nice discount!

Highly Recommended

by - verified purchaser
The GMAX is everything I hoped it to be the fit and comfort of the helmet is amazing. It's a little heavier than what I'm used to in a helmet but the many other features outweigh that and the lighting is awesome I've even received much interest in the Gmax and I highly recommended it.

GMax GM54S Helmet

by - verified purchaser
This was a good buy for me. I have a big noggin and needed something that would fit it without feeling like my head was in a vice. It works well, reduces the noise levels greatly and I can wear my phone headphones with it on. On the downside it does fog up when I first put it on even with all the vents opened and it's a bit heavy. When mine starts to fog I open the primary visor just a crack and it goes away. I love the built in sun visor and the flashing light on back. Also if you are an occasional cigar smoker like me you can raise the entire front of it and smoke a cigar while still wearing helmet. Overall, this is a good buy and Jafrum shipped it quickly.

GMax GM54S Solid Great Shopping Experience And Product

by - verified purchaser
Being a new rider and looking for helmets on the net is not an easy task. I went to my local shops around town to try some on I found a few that I like but the prices where way out of my budget. After that doing more research I came across Jafrum and found the gmax gm54s. I have to say the video review and comments made me feel really good about shopping here. And having communicating with Jafrum for details about my order by phone and email I I have to say thanks guys your service is amazing Now helmet on and of we go riding Thanks guys for the great products and prices. l'll be shopping again soon and I think that a vest will be the next item.

Great for the $$

by - verified purchaser
I just received the Helmet and it lives up to the reviews. I also have an MX Gmax that I use for my sled and DRZ, and I like it more than my Klim helmet. I have a 22 3/4 in head but chose the L over the M. There are other posts recommending going up one size and I agree. A medium according to the sizing chart would have been too tight for me. I'm looking forward to using the helmet when the temp here in Wisconsin warms up.

This was a very good buy. I always get compliments from other riders asking about it. It is comfortable and the matte version looks great. It does seem to fog up when not going very fast

Great Helmet

by - verified purchaser
I wanted a modular helmet for riding in the cooler weather. After looking at a local shop I fell in love with the fit of the 54s, search the web and found the best price was here! The local store wanted $199 I picked it up shipped for $129. I have ridden all winter in Colorado with this helmet and love it. I have a full windshield and am able to ride with the front open and not get my head jerked around.
