Comment: I have always used either HCI or Fulmer helmets. I decided to give the Gmax GM55S a try. This is by far the best overall helmet I have ever owned. As soon as it arrived I put it on and rode for over 50 miles. I hardly knew I was wearing a helmet. It is very light and comfortable. Great buy!
Comment: When I first put it on I was a little disappointed with the fit. When I measured my head - 60 cm - so I ordered the large. It fits very snugly. Almost too snug. But when I am out riding, I am almost unaware that I have a helmet on. And I would be happier with it if the sun visor came down another half inch. But all in all I am happy with my purchase.
GMax GM55S Helmet Solid
Comment: Jafrum comes through again! Great product, lightweight as stated so you can ride for and extended period of time and not suffer any head or neck pain...if you do. GREAT PRICE! The helmet is excellent if you're looking for a half-helmet with a great look. Jafrum delivers as promised, which is why I continue to buy from them! Make sure you order one or even two sizes larger than you normally would order, as the helmet sizes run small. Jafrum is the best!
Overall not bad
Comment: This is a very light weight helmet. The fit is good, but as my Wife said...It loos a little "Bulbous" while on. Not as sleek and low profile as I had hoped for, but overall not a bad helmet. Jafrum once again surprised me with ease of purchase and speed of shipping.
Spring Hill , TN
Good, Solid Helmet...though....
Comment: I have been looking for a low profile half helmet and this looks low profile on some people....not on me. It is the most comfortable helmet of the three I purchased from Jafrum (the Vega Naked and the Checkered Pudding Bowl being the other two) and although, the Vega Naked is the most low profile half helmet I could find, this GM55 is so comfortable that I just might keep all three and switch them out...the visor does not come down far enough in my opinion, but still looks cool when down. It gives it an aviator helmet/pilot look. You may still need your glasses on underneath, but it is one comfy helmet! Great helmet for the price and it's DOT certified. Nice hemet. At $58 you can't go wrong in giving it a try....especially with Jafrum's generous 60 return policy!
Great Half Helmets
Comment: Bought two, one for my son and one for me. We love them, they are light wieght and comfortable.
Comment: i really dig this helmet. it a excellent fit, sit's low on my head and very light weight. it a true extention of my melon! at 85 mph....oh aa i mean 70 mph i felt wind no blow back or pull up on this helmet. the visor down really help in aspect.
if you planning a long ride i highly recommend ear plug for the loud wind noise which our expected with these kind of head gear.
this is VERY COOL looking bucket.
it even made my ugly mug look good a feat in it self !!!
overall i give it a 9.8 out of 10. whoaaaa
Great fit at a great price!
Comment: By far the most comfortable helmet I have been able to find. The flip down shield is of no use. Just goes to show that you don't have to spend a lot of money for a quality helmet!
Comment: Its light weight, good price, and is true to size. I like its no frills look. Good summer helmet. The sunshield works great. One modification I would like to see added is on the sunshield to where the helmet can hold more than one shield so you can have both clear and smoke at your disposal.
Gmax Helmets with retractable sun shield
Comment: Helmet cam on time and fit perfectly. I usually wear medium but ordered a small and was very pleased. Love the retractable sun shield.
Baton Rouge, LA
Love my GMAX
Comment: Finally, the helmet to solve my problem with getting a helmet to not look stupid on me. Am VERY happy with it and really like the neck curtain. Follow the instructions to order a size smaller than usual. I'm normally an M but ordered the S and it fits perfectly. Actually, the fit and comfort is as big a plus as the good proportions. But thats not all. I also really like the visor. Found it not really up to it for over 100 kph as the wind then starts blowing up under and blurring your vision but brilliant in showery weather as a foil to fogging glasses. Was a great saver on a 3 day group ride last week in the wet.

Gmax Gm55S Helmet
Comment: My husband loves this helmet. Especially likes the visor that can be lowered. No complaints. Gift for my hubby.
Great Motorcycle Helmet
Comment: Very lightweight and comfortable, the wind doesnt pull it off my head like other half helmets I've tried due to all the air flow inside. Very cool and comfortable on a hot day. Retractable shield fits perfectly over my glasses as well. Love this thing!
Comment: I received this helmet as a gift from my wife. It is very light, cool, and comfortable, and the fit is such that it sits low on my head so it is very stable at highway speeds. The only thing I can say regarding improvements is the chin strap needs some hook and pile (velcro) to secure the end of the strap because the attached rubber band doesn't hold the strap so it flaps around in the wind. The drop down visor and the neck curtain are nice features, and I found that the visor drops down far enough to keep the wind out of my eyes (unlike some of the reviews I've read on the helmet). Overall I'm extremely happy with the helmet, and Jafrum has the best prices that I've found on the internet.
THE BEST -- bar none
Comment: Comfort - Excellent
Fit - Excellent
Visibility - Excellent
Retractable Visor - Unique/Excellent
Get It -- Excellent -- GET IT
Comment: Great helmet! Very light and comfortable. Visor works well, too. Also, it fits into my FLHX saddle bags, which is a nice benefit.
GMax GM55S Helmet
Comment: Nice helmet...great price...looks the same as the $150 helmets...I took a size smaller than I usually do because of some of the reviews I read....turned out perfect!!!
Comment: Order one size up.
Nice helmet for the price
Comment: Great value and very comfortable. I ordered one size larger than I measured and the helmet fit perfectly. Not as low profile as I had hoped, but still a really nice helmet.
GMax GM55S Helmet Review
Comment: Best half helmet I have owned. Only complaint is no snap to hold the end of the strap.
Mt Sterling, Kentucky
Helmet was OK, but...
Comment: I have a massive cranium apparently, so when I measured my head I went to for the XXL and it was a little too small and the visor was goofy. I am betting that the prototype for this helmet was for the regular head size person. Great deal for them, I'm sure. Gotta keep on looking Big Heads out there.

Comment: very happy with this helmet would have given it a 5 star if the visor did come down farther.

Gmax GM55S Solid
Comment: This is my first helmet for my bike and it is a great helmet.
I bought matt black and looking sleek!
It does the protection but give you little bit of Mushroom head, but I can deal with it.
Everything's good except for one thing!
Instruction for changing visor is not described well and I am having hard time trying to change the visor!.
But my overall rating for this price is awesome!
East Lansing, MI
Comment: Helmet is awesome! It fits great and the extra liner is really comfortable. The regular liner does not attach in very well but it is manageable and, for the price, it is not a deal breaker at all.Granted, I just use it for in town traffic (no long trips or interstate) so I might not be the best one to judge whether or not to purchase. I have a more heavy duty helmet for that.

GMax GM55 Solid Helmet Review
Comment: Great helmet, see a lot of comments about the retractable visor don't come down far enough, all you have to do is push up back of helmet or pull Down front, at times this makes a world of differents in a down pour.
GMax GM55S Half Helmet Review
Comment: I was looking for a good solution to being able to wear my prescription glasses which I only need at night. Goggles take too much periferal vision away for my liking so I ordered the GM55s and the clear shield to replace the sun shield......Perfect! Combine that with the fact that the GM55S is A LOT more comfortable than my HD brand bucket. Once again JAFRUM delivers with good quality, affordable solutions that show up FAST.
Nice helmet, good buy
Comment: Borrowed a friends half helmet to try. I liked it for short rides around town, but helmet was a little heavy. I shopped around and found the Gmax GM55s would suit me better.
I ordered the XL. When it arrived, it was a little too tight. I returned it to Jafrum who mailed back, at no charge, the XXL. It fit great. Lightweight helmet with sun visor at a good price.
I hope I don't have to test the crash worthiness.
Jafrum was a good company to deal with. Easy ordering, quick response.
Gmax GM55S Helmet Review
Comment: Excellent product, fit is great and I like the shade. I would definetly recommend this to others.
Just As Expected
Comment: The GMax GM 55S was just as advertised. Thought I needed a large but read reviews and ordered a size smaller. The medium fit perfectly. I ordered the yellow visor for night time riding and I think it will work perfectly. The weight is great, much lighter than my Bell. Product shipped as promised and received a day sooner than expected. Will definitely shop Jefrum again. Awesome service.
Fox Lake, Il
Just what I was Looking for!
Comment: I have wanted a half helmet for awhile and finally found the one I was looking for! The fit is perfect and the detachable neck curtain is definitely a bonus! The padding is awesome and the low profile doesn't give you the "mushroom" look. This company offers more gear/accessories at a better price...and I have compared!!! I WILL be a return customer to Jafrum!!!!!!!!
