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 value Great lightweight and stylish helmet. Shape of the cheekpads, enable you to install intercom/speakers without an issue. I love the graphics and the shape of AGV helmets. Highly recommended if their shell fits your head shape. September 15, 2014
Could be better Air flow is minimal - only a couple places you can adjust to add or reduce air flow and they dont regulate a large enough flow of air (two above the forehead and one at mouth level but they;re small). Helmet whistles a little once you get to about 35mph matte black helmet scratches very easily so be careful if that's your selection August 12, 2014
Perfect for what I wanted. Exellent Helmet for the price. It looks good, sleek, no real special features. I got this helmet for the noise and weight rating. I am very pleased on both accounts. It is very quiet even with all the vents open and the weight is very light. Great for long rides. The vent setup is pretty good as well. Great helmet for the price. Definitely will go AGV again.

I wish I hadn't bought it. This helmet was not designed for folks who wear eyeglasses. I had distorted vision wearing this helmet because the glasses were "scrunched". It is a round oval rather than an intermediate oval. July 21, 2014
So far, so good I typically use my helmets year round for about 5 years before retiring them. My last lid being a Nolan X-Lite 602 Stoner replica. I also had an AGV Stealth I used on occasion but was suppose to be a passenger helmet. And my favorite helmet of all time was my Arai Quantum F Raptor. So how does this new AGV K4 stack up? Very well! I feel like they've upped their game in terms of materials, features and finish. It's very lightweight and was comfortable for me right out of the box. I've been on a few half day rides and no issues, smells like a brand new car. I can feel the top vents working. The chin vents do a fine job of keeping the shield fog free. It comes with a fabric chin curtain which is nice for keeping the wind out. I decided to skip the graphics and I'm quite pleased with the matte black. Looks classy and the nice helmet shape speaks fo for itself, doesn't look cheap to me. The shield release mechanism is way improved. My only complaint is the dark tinted shield I ordered with the helmet doesn't seem optically sharp and I seem to notice a bit of distortion. But I can live with it. Noise level is acceptable. I currently ride a 2008 Triumph Tiger 1050 so I get some fairing/windscreen protection. But I always ride with ear plugs so it's not any louder than my previous helmets. I also added a Sena SMH-10 which matches great. Although I thought this helmet was going to have actual pockets for the speakers like some of the other AGV lids (Horizon, Skyline). But I managed to fit the speakers in there without hurting my ears. Overall very happy with my purchase. Looking forward to the next 4-5 years of riding adventures with it. July 7, 2014
First Helmet, nailed the perfect one with this choice! Beautiful Helmet! As a first helmet I feel its the best one to have, simply because I cant ask anymore from this thing. It has everything I could possibly want in a first helmet. Its light, fits great, great view, and I "FEEL SAFE." June 17, 2014
great aerodynamics The helmet feels great even at 150mph. The noise is a little loud but not unbearable. Should use hearing protection anyway. May 12, 2014
Great Helmet But ! This helmet is not great for speed over 150MPH Helmet vibrates violently at high speeds, Now that I sold my yamaha R1 And Own A KTM 950 SMR it works great for me now. March 24, 2014

RevZilla Store asked: Why did you choose this?
Tyler P: This helmet is highly underrated. I think a lot of people look at the price and think no good but I beg to differ. It's super light for the price, has great anti-fog, decent ventilation and doesn't have much wind buffeting which you may find are typical issues with helmets in this price range. Fits great, looks great and the graphics look 10x better in person under the sunlight. Highly recommended lid. Jun 27, 2014

Catunda: HB848,
My head is 56 cm and as per AGV charts I should buy a small.
I did buy a 2012 K4 Explorer (white), small. There are two snaps right on the forehead that bothers a little too much because the helmet fits small. I had give this one to my wife and she loved It, her head is 54,5 cm. Airflow is awesome!
Peace out.

RevZilla: The Icon and AGV size charts reference a 24-24 3/8" for the XL size, however, it is always best to take an accurate head measurement and contact customer service at 877.792.7955 or cs@revzilla.com with any fitment questions or concerns. May 1, 2012
