AGV K4 EVO Helmet - Solid 4.5 5 74 74
can't go wrong with matte black This helmet is the sexiest helmet for the price point November 9, 2015
I would buy it again! You can't beat this helmet for the price. It is very light, and has great airflow. The liner gets a little out of whack sometimes, but other than that I have had no issues with it. October 19, 2015
Perfect for my head shape - more round than oval First off, the Red Arrow graphic looks fab! As Anthony says--it'll be phenomenal even after 5 years. Secondly, but more importantly, this helmet perfectly fits my more round than oval head. I got this after trying many other helmets that gave me really bad pressure points on the sides of my head. Anyone having concerns about fit should talk to the supreme all-knowing Gear Geeks; they saved me at least a week of hassle! Thirdly, it's a good quality lightweight helmet for the price. But, the liner and comfort is just OokAy; perhaps in accordance with its price. Overall I am just glad that I didn't have to order a helmet from the asian market (where I previously lived) for my more round than oval head shape. October 7, 2015
My Last AGV I really wanted to love this helmet: great visibility, good airflow, BT ready and it does look nice but construction was a letdown. I found the following: 1. The padded liner is very cheaply made. The pad at the forehead will not stay in place allowing the sharp ridge of EPS to contact my forehead. (see picture) 2. Airflow is not as good as the Horizon. 3. Not related to quality but this helmet is more round then the Horizon. Ultimately I had to swallow my investment because I will not wear a helmet with liner defects. Even though I love AGV for its visibility and weight, this is my second and last AGV. Both suffered from liner issues and that is where my head lives. August 3, 2015
Decent helmet for the price Been wearing one of these for almost a year now - it's a good helmet but IMO it's quite loud, even with all vents closed, and there's some quality/durability issues that could be addressed. The good: - fits well - I typically wear a large helmet, I bought a large, no complaints. - Vents move enough air to keep from fogging if you're going more than 30 mph, even in actual fog. I commute 25 miles in the Portland area, 20 or so of which are on the highway through the valleys west of town, where it gets VERY foggy sometimes. Never had a problem with the visor fogging, just water condensing on the outside - Visor is easy to swap out - pads and liner are easy to remove for cleaning The bad: - Noisy. I don't have much experience with other motorcycle helmets but I always wear ear plugs in this thing regardless of what speed I'm going to go, and I'm not on a loud bike at all - it's the wind that bothers me. - Visor mounting system is fairly low quality. The visor mounting/ratcheting system is essentially two pieces - one piece that it actually rotates on, and one piece that clips in to a small channel that has grooves in it for the ratcheting action. This smaller piece that does the ratcheting has gotten worn from flipping the visor up and down enough that it doesn't stay in its groove anymore unless I move the visor very deliberately - no more whipping it up and down willy nilly or that piece won't stay in its channel and the visor won't seal until I push that part back into its channel. Easy to do while riding but it is annoying. - The plastic doohickey on the back that forms the point and houses the rear vents is VERY EASY to break. The helmet fell off my foot pegs once and landed directly on that - it cracked in two places. The little tabs that hold it onto the helmet also have worn down a lot (for no apparent reason, I never remove it) and at some point I'm assuming the whole thing will fall off, leaving me with an awkward looking helmet. I'd say it's a quality helmet but the visor ratcheting system and the rear vent cover leave a bit to be desired. For the money, however, it'll last you if you take care of it, and the visor can easily be fixed by replacing it. Not so sure about the rear vent cover. May 7, 2015
Dude. Sweet Light weight, decent airflow, very low profile helmet. Very quiet when your face is level. Agv's site says this is a sport touring helmet and the aerodynamics agrees. When you tuck the rear spoiler/vents work well. Errs slightly round in shape, but fits me very well now that it is broken in. May 4, 2015
Awesome I love this helmet. It's light wight, stylish and comfortable. For the it's not a bad deal at all. Thinking about getting another one my self. May 3, 2015
Saved my life I wrecked in this helmet face first going 60 mph. (was hit by a car) This helmet saved my life. The ECE certification is very similar to the snell cert and is the most common internationally. This standard is used in MotoGP. Not only did this helmet save my life, but it's comfortable, quiet, and light. For the price, I think this helmet is the best in its' class. Highly recommended. Just bought another. March 18, 2015

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.

Reply to Jon Good answer? Yes (0) No (0)
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
Reply to Carlos Good answer? Yes (0) No (0)
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
Reply to Edward Good answer? Yes (0) No (0)
brian s: You answered your own question when you stated you love your k3. Unless your in the market for a new helmet I would love the one your with. Aug 7, 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

Steve Y: I installed the Sena SMH-10 (universal) communicator and it works perfectly. Might take some trial and error to get the speakers in a comfortable position. There are no cut outs for the speakers. But the cheek pads are thick enough that you won't feel the speakers. Hope this helps. May 6, 2015
