GMax OF77 Helmet

The GMax OF77 Helmet is based off of the very successful GM67. It features the Spa Soft and CoolMax interior and multi-density cheek pads. The OF77 is like having two helmets in one. It offers the comfort of an open helmet, plus it quickly and easily converts to a full face helmet for those looking for increased protection and comfort with the installation of the optional jaw piece.

Features:

  • Lightweight DOT approved Thermo-Plastic Alloy shell
  • Anti-fog coated inner sun shield easily raised or lowered with a lever located on the exterior of the helmet
  • Cheek pads feature a multi-density foam construction creating a superior fit
  • Optional removable jaw piece (sold separately)
  • SPC top front vents/interior and styro designed for a controlled air flow
  • DEVS 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.
  • Large eye port for improved peripheral and range of vision
  • Spa Soft, CoolMax comfort liner and cheek pads move the moisture away from your body and the fabric dried quickly
  • Removable/washable interior and adjustable cheek pads allow for more comfortable sizing
  • Deluxe ear pockets with built in space for speakers for use of communication systems
  • Soft padded chin strap
  • Helmet bag included
  • Optional LED light kit (sold separately)

Not impressed by Assembly of product
It is still winter in Michigan so I have not ridden with the helmet yet. Cannot say if the wind noise is high or low for example. What I can say is that I was very disappointed when I found the interior sun visor was not connected on both sides I spent considerable time fussing with it to get it attached correctly and it remains to be seen if it will perform as expected. . . Also the clear visor does not seem to be formed properly. there are two slots, one on each side of the helmet that the visor isdesigned to seat into, which are intended to hold it in place in case of an accident. The visor misses those slots and therefore the feature imay not be operative when needed. This helmet is a replacement for the Gmax 67S which served me very well by protecting my face in an accident. It was the reason I purchased this new helmet. Time will tell how this new helmet preforms. Clearly the factory needs to improve their quality control and final inspection procedures.

Good fit, good price
The helmet fits pretty well and the overall air flow is good. The noise level is fine but I have a fairing so I don't get as much of the wind as some reviewers. The built in sun visor is a nice touch so i am not reaching for sunglasses or trying to find a place to store a clear shield for the night ride as well.

Nice Helmet, but LOUD
This is only my second helmet - first was an HJC 3/4 that I had for years. This helmet fits much better, more snug and secure. Love the drop down sun visor! I tried on other GMAX products in a local store, but purchased here because of color selection.

I have ridden with this helmet about a dozen times. What I don't like is the noise. There is a lot more wind noise than my old HJC helmet. Not so much that I wont keep the helmet.

Stylish, comfortable and useful sunscreen
I like the way it looks and feels. I like the sunscreen that goes up and down with an easy touch lever. I like that the windshield has 2 down positions.

I don't know if it is noisy on the highway because I only ride in the city, and noise has not been a problem. Although it has 2 adjustable air vents, I thought it was not as cool as others I have used when the windshield is completely down. Partially up, it's fine.

All in all, I like it and would recommend it.

Good overall
Nice and cheap helmet, does what it needs to do. The fit was a good true, i ordered online with my size without trying one on at a store and it worked great. The sun shield included is a little small but it helps if you dont want to cram your glasses in with the helmet or if you forget them. Air flow works fine, it is an open face helmet so you cant really be warm riding with it. I use it only for short faster trips or just to go for a smaller ride and enjoy some wind on my face.

Great for the $$$
Been riding with this helmet for a couple of weeks here are a few findings...

*Order 1 size up because I wear a bandana but the one size up ended up being a "True Fit"
*Average loudness, I have had much worse
*I also bought the interchangable peak sun visor, mainly for the look when riding without the face shield, works great and easy to swap out
*I purchased the chin guard with breath curtain, snug fit, works well, I only rode with it once because it hasn't been cold out. The one thing I noticed is it it extremely difficult to get the helmet on with the chin guard fully attached, but if you really pay attention when installing it, you will feel that it clicks twice on each side, by starting with one click per side, I was able to put the helmet on and then do the second click on each side.

Overall I really like this helmet and am going to order a second one for my wife

Better than expected
I highly recommend this helmet. Due to New England weather, I have only ridden with it a couple times. It fits very well, the noise level is acceptable and I hope to never be able to report on it's durability and functionality. I would purchase this helmet again.
