Improvements in weight and comfort, the K4 EVO represents the ideal solution for those who want an attractive, safe, comfortable helmet with an excellent price/quality ratio.

Great Helmet! This is truely a great helmet! I would recommend this to everyone looking for a new helmet. Top of he line features for the price! September 10, 2012
So this is what a good helmet feels like! After I got my last helmet, I was never really satisfied with it. It fit... but it didn't fit very well. What was off was the Shape, not the size. After a brief chat with Revzilla's Gear Pro's, they turned me on to a couple different brands that gave a longer oval like what I needed for my Lycan shaped head. It fits perfectly. Thanks for the expert advice that made all the difference to me. I especially love the fact that it's quiet. Light and Quiet. I don't have to wear Ear Plugs when I'm riding. Even if I'm cooking along at 90+ on my ZX-11. Thats a plus! August 14, 2012
Excellent!! Purchased this to replace my Scorpion EXO-700. Fits much better and comfy, noticeably lighter and very eye catching shape and design. You could really feel the air flow and heat dissipate when you tuck in. For the price, this really is a great helmet!! July 16, 2012
Excellent helmet value Decided that I needed a new helmet as my Bell Star helmet was seemingly breaking down (though that is another review). Considered getting a Shoei, Shark or Arai, but I remember I have always had good results with AGV helmets so I checked out all the reviews. Listened to the Revzilla review and bought the K4 EVO with the black Explorer graphics.. I must say I am very pleased with my decision. The helmet is extremely light, quiet and very comfortable. The shield mechanism is as easy as my Bell or older Shoei, which is the gold standard. The helmet is beautifully finished, the graphics are excellent and the liner is soft and nice against the skin. Is it perfect? Of course not. The air flow could be better and I wish the chin vent would vent air through the chin bar, but that is a minor point and it is nice that there is some serious padding in that area, helping with safety. It is also a bit small and I needed to go up a size to an XL, when I usually take an L in other brands, such as Shoei or Bell. All in all I think the K4 EVO is an excellent value and a great helmet. Highly recommended! May 29, 2012
Airflow rocks, great for commuters! Listen to Anthony's review on this helmet. It is just about it, but the two snaps located right on your forehead bothers a little too much if you don't buy the right size. The helmet fits small, just to clarify, my head is 56 cm and I got a small according to the chart. I should have bought a M size, but no problem because I gave this one to my wife and she says the Helmet is "to die for", whatever the %#}¥ that means anyways. LOL. I strongly recomend It for commuters due to the airflow on this helmet. February 14, 2012

MadOgre: Yes, the helmet is that color. It looks much better in person. Also, the graphics give the compass a more distressed look than you see in the picture. It looks very cool and more legit. Aug 15, 2012
