AGV K4 EVO Arrow Helmet 4.4 5 63 63
Great helmet Great helmet for the price. It looks good and works well. It has a good fit. August 2, 2016
Good Value Helmet I recently purchased the stylish AGV K4 Arrow in Blue/White and the graphics on this helmet did not disappoint. It's got a very stylish shape and bold graphics which compliment one another well. Coming off of an older generation, Shoei RF 1000 (which I've had for the 5 year limit) I was excited for an upgrade. The Shoei was a comfortable helmet, but lacked even the basic features of the AGV, such as a removable liner. Being that the AGV is a lower price point than the current Shoei offerings, I decided to give it a try. When the AGV arrived I quickly suited up, and took off to evaluate my purchase. The internal padding material is comfortable and seems to do a good job of keeping your face dry in warm conditions. I'll enjoy the easy removal of the internal lining over as it'll allow me to wash as necessary. Keep in mind that the neck roll does not remove, which still means that at least one piece of the padding will need to be washed with the helmet. Removal and re-installation of the liner is simple enough with 3 snaps for each cheek pad and 4 for the head lining. The fit of the helmet is definitely more round than oval. I would recommend checking into the sizing chart for more information and try the helmet on before taking it on a ride. Revzilla worked with me through the process to get a helmet that fit correctly, but you could surely save some time by checking the chart from the start. Airflow on the helmet is okay. I wasn't overly satisfied or disappointed with the flow. I'd say it is comparable to my Shoei, which I'll consider good for a helmet at this price point. The air vents, however, I can attest to being very easy to control with gloves on, opening and closing without interruption. The nose-piece does a great job working with the visor in it's "nearly closed" position to deflect air from your eyes and not dry them out. Similarly, the chin gator is a nice feature to maybe keep noise down and unwanted airflow to a minimum, I'm not sure because I haven't taken it off yet. I purchased a visor to go along with the helmet which added a bit more style over the clear version. The quick release visor is great and makes swapping out at night a breeze. As far as the styling bits on the exterior, time will tell on how well they hold up. The rear spoiler on the helmet appears to be a little brittle, and I'd suspect one day it will break. However, at this price point it would be easy enough to purchase a replacement piece and carry on. Overall, I would recommend this helmet for purchase to anyone looking for an entry-level, everyday helmet that is reasonably quiet, comfortable, provides good airflow, and stylish. May 31, 2016
Great Value for a good helmet I just barely got into riding so my review is just my opinion for this helmet. I bought it on the closeout deal and it was an amazing deal. I love the look and it is comfortable just a little pressure on the forehead or just needs to be broken in a little. It seems like it has good airflow, my head hasn't really sweated too much in it. Some of the cons to this in my opinion though is it is not as long as I needed my chin kind of pokes out the bottom. Also I don't really have anything to base it off of but the noise level seems loud in the helmet. Not excessively so but enough that I wear ear plugs. April 26, 2016
Best attribute is light weight but other than that nothing special First off I ordered a medium and it fit pretty tight so it runs small. I don't know if it was the smaller size that was the problem but the the helmet area under the face shield inside is really close to your mouth, I don't even know if you could fit a bluetooth mic there, and it being so close to your mouth it fogs the face shield easier and is just very annoying. I found this helmet to be very loud at speeds over 40mph as well. But if your looking for a super lightweight sleek looking helmet its very nice, it doesn't even feel like your wearing a helmet. I would definitely order one size larger. February 8, 2016
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
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
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
