GMax GM54S Modular Helmet

by - verified purchaser
I tried several other modular helments and they were too tight on my cheeks. Anyone that ever wore a helment that was too tight very long knows what i'm talking about. I ordered a GMaxGM54S and as usual with Jafrum the helment arrived in just a few days. I was impressed with the quality and most of all the fit. IT FIT !!! With so many companies selling motorcycle accessories on the internet today. It is so good to find a company that you can trust. I trust Jafrum, for the best service, the best product at the best price. You can too.

I Love My Helmet

by - verified purchaser
Jafrum's has excellent customer service I just had to say that first. I was sold after watching the video review for this helmet. I ride a lot at night so the blinking light really put the icing on the cake when choosing this helmet. It does fog up that's the only drawback.

A little loud but fits well

by - verified purchaser
The fit is great. The double visor is very nice to have, still need a little blackout up top in the morning sun. The light on back is ok. Seems to be a really cheap led set and I question it's reliability through more than a few rain storms as there doesn't seem to be any seal keeping water out of it. Plenty of venting options to keep your head cool. Needs a nose breath deflector though because it fogs up at a stop, every time. For this price, the helmet is a great bargain.

First modular

by - verified purchaser
I've bought nearly two dozen full face helmets over the last 25 years of riding but this is my first modular. I selected Gmax because they are known for offering a great value product and the 54s delivers. On fit I must first preface that I have a long oval head shape. With EVERY helmet I buy I get tremendous forehead pressure and this was no exception. I've developed a good method of shaping the styrofoam inner shell to relieve this on all my helmets. I did this on my Gmax 54s and now the fit is perfect for me. The overall quality of this helmet is good. While its not on par with the high end helmet makers its still good especially at this price point. The biggest negative I will remark about is that its on the heavy end especially when its flipped up. Bear in mind this is my first modular so it may be typical?? The flip down visor(which I also have in my current full face) is something I will never be without again as its the best feature ever. The rear facing multi-setting light is a cool touch although I question how long the switch will last. Overall in a value product its two thumbs up!

Like it so much I bought two

by - verified purchaser
I have owned many helmets in my 40+ years of riding. I must say this is one of the best. The GMAX fits like a charm and is very comfortable on long rides. I really like the modular design which allows you to take a drink without removing the it. The internal sun visor is really nice for those like me who wear glasses; now I don't have to carry sun glasses. And the option of adding a third brake light is a great safety enhancement. This is a great lid that compares favorably to far more expensive models. Highly recommended, and the customer service at Jafrum is top rate.

Nice Helmet

by - verified purchaser
Haven't had the helmet for long but so far I like everything about it except the weight. However, once I start rolling I no longer think about the weight. Both the visor and the sun visor are crystal clear. I trusted the sizing guide and am glad I did. The helmet seemed very snug at first but I quickly got used to it and now it feels fine.

GMAX54S Helmet Review

by - verified purchaser
I bought two of these helmets. One for me and one for my husband. We both measured in the medium size range, but after trying on a friends medium we decided to order larges and they fit perfect! Lots of air vents. The drop down shade is great. Good quality helmet, for a great price. We both LOVE IT.

THE BEST HELMET FOR THE MONEY YOU'LL EVER BUY!

by - verified purchaser
This helmet is top quality all the way. It compares well with helmets costing 3-4 times as much. You simply can't beat the bang for the buck. The features are as good as anything you can buy. Great ventilation. The fit and finish is impeccable, and everything works exactly as it should. When and if I have to buy another, I hope that they're still making them, because for me, this helmet is the only way to go. The only thing that I would note for prospective buyers is that I found the size chart to be a little off. I had to go up one size to get the right fit. Other than that, it's all good.

Amazing, quality Helmet

by - verified purchaser
This is an amazing helmet, especially considering the price. It has many features only found in more expensive ones. After talking to a Jafrum rep over the phone, I was able to get a perfect fit. It is very comfortable and is not very heavy at all. One thing I personally love is all the many vents. With all the vents open you actually have a breeze going through the helmet! Another nice plus is the back light for visibility purposes. The chin screen is also a very nice feature for colder weather. It also blocks out wind noise rather well. The speaker pockets are nice for my headphones. My favorite feature, however, is the retractable sunglasses. It is such a great feature and is very simple to operate. All these features, plus its great looks, makes this one of the best helmets for the price that I have ever seen.

Great value!

by - verified purchaser
Solid helmet, lots of vents, solid locking modular arm, sliding tinted shield is great. If you have a round head, the size chart is spot on. If you are an oval or long oval (like me) bump up a size or two depending on how oval. Hope to never have to test is durability, but I feel much safer after years of riding with a half helmet. Missed the freedom of the brain bucket so I took the face sheld off…good compromise and my wife is much happier :)

great helmet but not for wet weather

by - verified purchaser
I like the helmet. The fit is great. First helmet had broken arm on inner shield. Second was fine. Installed brake light module in about 5 minutes. Had to reglue the vent screens in back because they were barely holding on. Wore it in the rain and it leaks bad. The front visor had water dripping down the inside into the chin vent area. When I removed the helmet the top had water inside it to dump out. Do not buy this helmet if you live in a wet area out ride in the rain much.

GMAX54s Helmet Review

by - verified purchaser
I am new to riding and didn't know where to start with purchasing a helmet. The sizing videos were extremely helpful and went a long ways towards helping me figure out what to look for. And the reviews were educational as well. I bought two of these, one for my bf and one for me. We just got back from a 2000 mile week-long ride, and I will have to say, these helmets were wonderful! Fit was spot on, comfort was great, and we both loved the inner sun visor. The center button on the chin was easy to operate for someone like me (with hand mobility issues) and the light on the back was the icing on the cake. I definitely recommend this helmet!!

I ordered the wrong size. Jafrum was quick to replace it with the correct size at no charge. Great customer service both original order and the size replacement. The helmet is very nice for the price. Lots of vents, sun shield works well and comfortable. My only complaint is the helmet is a little louder than my full face

Best Helmet Out There!!

by - verified purchaser
I bought my first one a year ago and loved it so much I bought a second and am considering a third! I have tried on or owned everything from an inexpensive Bilt to a Shoei and this beat then ALL! Price point is amazing, fit is spot on and you can replace every piece on it! JAFRUM is AMAZING to deal with! I broke my interior visor switch and they sent me 2 for FREE!! Don't buy anywhere else, you won't get the same quality, price or service! THANK YOU JAFRUM!!

Great helmet! We have two of them!

by - verified purchaser
This is a well built, solid helmet, my wife and I both own one are are very happy with them. You can hear a little wind noise, I don't think there is a modular helmet built without some wind noise, but it is very acceptable and better than most of what you will find at this price level. We have Sena SMH-10 intercoms installed on them, no problems with the installation or the operation, sound quality is very good even at 75 mph, no windshield and Cobra pipes. The wind blocker under the chin helps quite a bit with noise and especially with the microphone. The helmet is very comfortable and snug, I was a little worried about the sizing but I followed the GMax helmet sizing table and the fit is perfect. The helmet is a little heavy, but it feels solid. The venting is excellent, the best I've ever had in a helmet.

Jamie M onMar 7, 2015
I really liked the first Gmax helmet I bought. It had the light in the back, too, but it was the solid face model. After a low side at 45mph scratched it up, I decided to try the modular model. Same great fit and more features than my previous helmet. This one seems to be a little noisier, and not as good in the airflow though. The face shield isn't as secure in the ratchet mechanism either, but that might be an adjustment issue? Good enough room to wear glasses under the sun lens.

Does this helmet have some lower chin apparatus to keep wind from coming up from under the chin?
Clayton S on Dec 18, 2014
Best Answer:It has a mesh netting that helps a little, but honestly i don't recommend this helmet because it is very loud. If you don't know what i mean by loud, it makes a lot of noise from the wind when doing anything over 50mph

Does this have the electric shield?
A shopper on Oct 5, 2014
Best Answer:I had to do a little research to figure out what you are asking about. No, the helmet does not have an electric anti-fog shield. That being said, I have two of these and neither has a fogging issue. My wife reported one incident where the shield fogged up. We were in Florida in extreme humidity and her helmet fogged up as it began to rain. It was very hot and literally 100% humidity. So, good value for the money, no problems, and fairly comfortable. The air venting works and I would buy these helmets again. Good luck.

what speakers fit this helmet?
Keith A on Apr 6, 2015
Best Answer:The foam ear pieces come out of the helmet and small, maybe 1 1/2" round speakers go underneath. I use the headset speakers from my communicator and they work very well. Just rode cross country and listened to music all the way. The helmet isn't the quietest unit around but it is workable. Most important is to get a communicator with the fidelity you want.

how much it weigh?
mary t on Jan 5, 2015
Best Answer:I don't know the actual weight, but it seems fairly light compared to the fiberglass Shoie Helmet I used to have. This is an Excellent helmet. I am Very Happy with it. With all the vents it stays cool while riding in the summer.If it's too hot you can ride with the windscreen up or the whole chin piece. With the vents closed,ot seals well enough to ride in the winter without a draft. Very sturdy.I would recommend it to anyone.
