AGV K4 EVO Sliver Helmet 4.6 5 15 15
Everyday wear So I've had my Red Large K4 evo for about a year now and it's an amazing helmet. The style is just what I was looking for, aggressive looking yet comfortable enough for extended everyday wear! The air flow is just about what you'd expect from a Mid-High end helmet. My only quarrel with the helmet is that about 6 months after recieving it in the mail the little red button on my chin strap snapped right off after riding home from work, so now I have no way to secure my excess chin strap. I guess I've just been too busy to Jerry rig something up but other than 1 cheap little red button, I love my helmet! June 27, 2013
Accurate sizing and great value Helmet is way lighter than comparable helmets by other manufacturers. After just one ride I could tell the difference in weight, making this helmet more comfortable than similarly priced models. Used AGVs helmet sizing guide and helmet fits tight (but not too tight) out of the box, which is good. Helmet will become more comfortable with more hours of wear. Purchased AGV K3 / K4 EVO Anti-Scratch Face Shield in mirrored dark tint which looks awesome with this helmet and fits well. April 16, 2013
Good Helmet for Oval shaped head! Good Price! I tried on many helmets in store to find that many of the helmets do not fit very well with my oval shaped head. After a few stores and many different brands and models, I found this to be the best fitting one for me. I wear glasses as well and found this helmet to fit my glasses best out of the many I tried on. I have owned it now for a few months and have had no issues w/ this helmet. Great helmet, good visibility, good airflow, and good price. Not much else I can ask for. Revzilla also has great customer service. Got XL which fit great in store to find it too big when received. Easy exchange w/ revzilla. December 19, 2012
Great Inexpensive Helmet I was looking for a helmet that was inexpensive but still very good quality with features like removable inners, nice graphics and solid build quality. I think this helmet is a very good helmet for the price. the action of the visor and general feel of materials if excellent, all for $249. I choose the k4 over the k3 because the quality is slightly better, in the end your paying 40 dollars more and you will get the value in return. The only disappointing thing about this helmet is it is made in china. even tho AGV is italian comany, like so many companies they have sold out and moved to china. I avoided a lot of brands because they state they are made in china. its hard to find that out about AGV, I was disappointed when i discovered this fact. I guess this is why the price is so low. I'm using this helmet on a street bike in Kathmandu, Nepal. it gets subjected to a lot of dust and fumes in the air plus in summer it gets really hot. all the inner padded items pull out and can be washed. after washing they fit a little more snugly as well. The visor snaps off for easy cleaning. I really appreciate these features. Air flow is pretty good, you cant ride fast in kathmandu, but the air flow of this helmet is noticeable at low speeds, the lighter colours help keep the helmet cool as well. I leave the helemt on the mirrors sometimes when Im parked in the sun and the helmet stays cool. the fit is quite good. i couldn't choose it in store, so I cant get the absolute best fit, but i am very happy and satisfied with the fit as quoted on the website. I measured my head and was on the low end of Medium, and this medium helmet fits as I would expect it to. Overall I think this is a great helmet for the price, shame its made in china. I think companies should try and get low-medium range helmets into the market that are not made in china. I dont need a hi-end track helmet, and the prices of Japanese helmets are so high you dont realize the value. November 26, 2012
Fantastic helmet. Great helmet at a good price, typical AGV excellent fit and finish. Quiet, and good airflow, though to be fair it's just now getting into the high 60's, but is very adequate airflow in hot summer weather as well. November 6, 2012
Great looking helmet with good features for price. Ordered this helmet to replace both my Shoei TZ R-1000 (Model previous to the RF-1000) and Icon Domain 2. I have been very happy with the purchase so far. In comparison it is lighter, has a better field of vision, more comfortable and is surprisingly a little bit quieter. The airflow was fine and I didn't experience any fogging up of the lens even with vents closed during night riding in the cold. The lens replacement system is one of the easiest I have used to date and didn't even need instructions to do it. My only gripes and these are quite minor is that the Chin curtain is not temporarily removable (once removed it cannot be placed back in), and there is a slight whistling sound when traveling above 95 mph (150 km/h). All in all, I am definitely happy with the purchase and will buy my next AGV helmet from Revzilla. September 9, 2012
Great Helmet for the price! Very good helmet would choose this over any hjc or similar brand in the same price range. Great style very light and comfortable, wind noise is good, for the price you can't beat it I would recommend this helmet to anyone looking for a great helmet at a decent price. I have shoei helmets and aria Helenets I was impressed with this helmet for the $$ it has a similar shell shape as a shoei rf1100 and rf1000 August 13, 2012
it is a nice chose. It is a nice chose if you don't wanna spend a lot of money to buy a helmet. July 23, 2012

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
