Just What I Ordered

by - verified purchaser
Very nice helmet matched my bike's color to a T. Jafrum delivered in 3 days I couldn't ask for better service. Will buy again when I need my next helmet. I couldn't be happier with the purchase.

Perfect!

by - verified purchaser
I am absolutely thrilled with this purchase. I've not seen a more functional and well-designed helmet...EVER! The front latch which allows the front module to flip up is easily accessible, even with gloves on. The latch which engages/disengages the sun visor is equally so. The ventilation ducts are well-positioned and also easily accessed. While I am very impressed with the functionality of the GM64S, it is the sizing that I am MOST impressed with. The size that I ordered (M) was spec'd for my 23" head and it fits perfectly. I look forward to many enjoyable miles in my new gear. IF YOU'RE LOOKING FOR A NEW "LID", BUY A GMAX GM54S...YOU WON'T BE DISAPPOINTED.

Great Helmet For A Hard To Fit Rider

by - verified purchaser
Finding a comfortable helmet, especially a full face or modular, is difficult at best. Sizes mean nothing today and motorcycle gear sizing is especially inaccurate. I started looking at Gmax because of its reputation for good fit and adjustability. I wear a 7 3/4 + hat and ordered an XL. It was too tight. I returned it for an XXL that fits like a glove. Thus, the only comment I have is that for my head shape, I went up one size. Love it!

Just What I Expected

by - verified purchaser
This is my 2nd Gmax helmet. It fits just right, has a solid feel, & is of high quality. I believe Gmax makes the best helmets under $200.

Meets Expectations

by - verified purchaser
I'm not one "to gild the lily" and will only echo the comments of other reviewers by saying that for under $200 and free shipping, I don't believe there is a better modular helmet available. We used information from our old helmets, as well as measurement guidelines on the site, for sizing and the GM64S's fit Goldilocks. All the features and benefits described on the Jafrum site are accurate and I recommend this helmet to anyone in the market for a reasonably price, modular.

Gmax GM64S Helmet Review

by - verified purchaser
I have always had trouble fitting a helmet.. The helmet is light, comfortable and well ventilated (96 degrees on a recent ride). Oh, and the Jafrum service? Superior! Shipping is quick and returns are processed promptly.

Gmax GM64S Helmet Review

by - verified purchaser
Jaw bar doesn't just lift up so it feels like its on top of the forehead, its up and back so its not pulling down, my wife likes that feature and it is lighter than the GM54. very quick delivery. Still trying it out to see if it fogs, but so far it fits good. Thank you.
