Great Helmet I've been wearing this helmet for a year and I love it. Fit is great and I love the red arrow graphics. Fit and finish has the look and feel of quality in materials and design. I bought mine in the philly store. The sales staff are all friendly and a pleasure to deal with. February 19, 2015
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. August 4, 2014
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
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

James O: I've had mine for I about 2 years, and unless they've changed it since then, it's a double D-ring. Best helmet I've ever owned, by the way. Apr 30, 2014

A S asked: I was wondering if the K4 evo comes with DOT sticker, and also my head size is 62 cm exactly and looking at the helmet size, should i get the XL or XXL, does it fit small or large? Nov 17, 2013
Answer this · Send to friends Good question? Yes (0) No (0)
James L: I believe the helmet is DOT approved. I found the helmet to run pretty true to size. I am typically between a XL and XXL. I had gone with the XL, as I feel it's important for it to be a bit on the tighter side. I hope this helps. Nov 18, 2013
Reply to James Good answer? Yes (1) No (0)
Ha N: It fits large for me, I usually get XL but I got the L and its a bit snug but fits better than XL Nov 18, 2013
Reply to Ha Good answer? Yes (1) No (0)
Jon M: I don't believe there was a DOT sticker on the back, just an AGV-K4EVO sticker. A DOT notice is sewn into the lining.
I have a 57 cm head and I'm wearing the medium. I believe you will get the right fit with the XL. It should be a little snug. Revzilla does a good job making sure you get the right helmet if the first doesn't fit.

Jorge B: Yes, it comes with the DOT sticker. XL i think, i have the L size, and fits pretty good, but a bit small i think. Nov 20, 2013

A shopper asked: Is there really enough difference between the k4 evo and the k3 to justify the extra $? I have been rocking a k3 for 2 years and I love it. Aug 7, 2014
Answer this · Send to friends Good question? Yes (0) No (0)
Carlos R: I myself own the K4 and my younger sister owns the K3 and both helmets are nearly the same IMO. Both are light, comfortable, have great ventilation and they're not the quietest but also don't find it to be loud or irritating when riding. I've been looking to get a newer helmet myself just to change up the look but I'm probably going for either the newer Shoei RF-1200 or the Bell Star. I say go with what you like but wouldn't really make the jump to a K4 from the K3 maybe get the AGV Corsa lol. Good luck with your new choice of helmet and always ride safe. Aug 7, 2014

Edward C: I own the k4 and my girlfriend has the k3 biggest differences I've noticed is the liner and the k4 front intake vents up into the visor to help with fogging Aug 8, 2014

Michael D: Can't give you the exact wt, I'm out of town, but it weighs less than the Suomy or HJC i have. I love my helmet! Have had it a couple years and it's held up well. Jul 11, 2014

jerry h: Not sure about exact weight, but feels very light compared to shoei rf 1000 it replaced. Be advised it seems to run small at least for me. Jul 10, 2014

A shopper asked: I have a fairly round head and find the S4 fits me perfectly. How does the K4 fit, compared to the S4. Are they similar in shape? Dec 1, 2011

mondrian8: Don't know about the S4 but the K4 is an intermediate oval - from above, egg shaped with the small area forward - my head shape. The K4 fits me with no pressure spots. Feb 15, 2013
