In the AGV K3 SV helmet review article below, in addition to physical review, user reviews from different countries are added to noise and visor sections to provide general information. Blue coloured texts contain redirection links and new tab will be opened when you click on these links.
Italian helmet producer AGV, produced K3 SV helmet from Polycarbonate which is 1. shell size weight is 1.49 kg (3.28 lbs).
AGV K3 SV, tested in Sharp laboratories and got a 4 star. But something more important than star is impact zones diagrams. While frontal bone, coronal suture, parietel bone, lambdoidal suture are passing the test with green color squamasol suture and temporal bone location passed the test with orange color. AGV K3 SV, has ECE REG 22.05 safety certificates. Every helmet that passes Sharp test has this certificate.
Unfortunately, AGV K3 SV doesn’t have double-d ring chin strap system and visor lock system.
If we generalize AGV K3 SV users feedbacks we can rate isolation of 5.3 over points. You should not be surprised with different reviews. The reason for this is all of us have different levels of hearing, riding styles, motorcycle types and motorcycles that offers different levels of wind protection and riding at different speeds. The wind tunnel test at 100 kmph (60 mph) which has been done by COAU the sound level in helmet is 94.1 dBA and got a 15.9 over 20. If noise level is an important criteria for helmet selection, we recommend taking dB levels of COAU as reference and see also: quietest motorcycle helmets
For ventilation there are two air ducts on the chin, three air ducts on the top and two air exits on the back. The pin that closes the air ducts on the chin is located inside of the helmet close to the chin side. All air ducts to the backside can be opened and closed totally. But you can’t intervene the air duct at the back. There is no chance to leave air ducts open at a certain level like some other helmets. COAU rated this helmet 6.8 over 10 for aerodynamics, and 13.1 out of 17.5 for ventilation.
AGV K3 SV has pinlock. Therefore, visor fog will not be a problem. There is micro opening system at visor. Working logic of this system is when the visor is closed it can bring visor to one level up and making it get more air from the tiny gap it creates.
There are three different plastic visor pin inside of the box. You can put the green one and get 1.2 cm more gap on top of the micro opening mode and you can position the visor at 5 different levels. If you put the red one the gap almost becomes 5 cm, it starts from the middle and you can position the visor at 4 different levels. The blue one is only for opening and closing so there is no visor positioning. Most of the helmets have positioning visors but AGV is really thoughtful with this helmet.
If we generalise user reviews for AGV K3 SV, we can rate wide field of view of this helmet as 13.7 over 15. Wide field of view may be similar in most of the helmets but vertical field of view is rarely similar. Therefore, vertical field of view should be considered as this is an important element. When you take position especially on sport motorcycle, you need as much as vertical field of view to see in front of you clearly. We can say vertical field of view of AGV K3 SV is at avarage. Vertical field of view of this helmet is rated 2.41 over 5 by COAU and visor wind proof level is rated as 10 over 10 by COAU.
Built-in sun visor can be opened and closed with latch on the left-hand side of the helmet. As in some helmets, you cannot keep this built-in sun visor at certain level.
AGV K3 SV, has been designed for Round Oval head shape and produced with two different outer shell size. If you don’t know about shell sizes we suggest you to read this article about shell sizes at helmets.

AGV K3 SV has breath deflector, glasses groove, speaker pockets, chin wind curtain, removable and washable cheek pads. Cheek pads and top pads are made from a comfy material. Speaker pockets of AGV K3 SV are designed for its own intercom system Side Share Easy Communication System that is sold separately. Therefore, we couldn’t fit some intercom models to this slot since these slots are smaller.
This is all the information we will provide under overview. You can find the summary in summary tab, check user reviews tab for user opinions, add this helmet comparison list and find the right helmet for you with filtering system.
|Helmet Type It specifies the type of the helmet, such as full face helmets and modular helmets… However, full face helmets are the safest type of helmet in the world.||Full Face|
|Origin Specifies the country that the product belongs.||Italy|
|Material Specifies the material type of the helmet.||Polycarbonate|
|Weight Specifies the weight of the helmet. Even though a weight of 100 grams seems light, it creates a serious load coefficient, when factors like wind coefficient are added to this weight.||1 49 kg|
|Sharp Rating Sharp is a company that was founded in 2007, which is controlled by the British Government and puts helmets through durability tests. They have always raised question marks as some models of upper class brands were given low ratings. Nonetheless, they are an independent institution that rates helmets by testing them all in the same way.||4 Star|
|Snell Certification Snell is a non-profit organization that was built in USA in the year of 1957. Snell tests are truly vigorous and challenging. Some models of the brands like Arai, Bell, Shoei, Hjc have passed this test. The number of helmets that could pass this test is limited. Snell standards are renewed in every 5 years.|
|Retention System It is the chin strap of the helmet. They are categorized as Micrometric or Double D Ring. Double D Ring fastening system is the one that is being used in MOTOGP. It is present in professional helmets and it is the safest fastening system.||Quick Release|
|Visor Lock If you are planning on using your helmet while driving with a speed of 240km/s or more, we definitely recommend you to get a helmet with visor lock. Otherwise, the force applied by the wind may open the visor of the helmet.|
|Pinlock Pinlock is perhaps one of the greatest technologies. It completely prevents the fog on your visor that is caused by moisture, your breath or the cold weather. Your vision is never restricted. It is not provided with all helmets.||Not Included|
|Emergency Kit Emergency Quick Release System. It is the system for quickly removing the pad in case of emergency. By holding the hook below the pad, you can rapidly remove the pad.|
|Breath Deflector It is a fog preventing factor for the helmets that don’t have pinlock. Another benefit of it is that if you lift the visor while moving, the wind won’t make breathing more difficult.|
|Glasses Groove This means you can use glasses with this helmet.|
|Internal Sun Visor It is the black visor on the helmets that looks like sunglasses and they are provided with UV filters. They can be opened or closed. You can think of it as wearing sunglasses.|
|Speaker Pockets Intercom is a device that connects via Bluetooth. Intercom dock is where the earphones of this device are placed. By connecting your intercom device with your phone, you can make a phone call, listen to music or connect with other intercom devices while driving. You don’t need to wear an additional earphone or another device.|
|Chin Wind Curtain It is one of the features that affect both isolation and comfort, since the helmets usually get wind from below.|
|Inflatable Cheek Pad Cheek pads of all helmets are flexible. You can see plenty of complaints about the helmets that were purchased a size bigger without considering the possibility of getting loose. This feature allows adjusting the pads according to your head without needing any other material, thanks to its air pumps that are located inside the helmet as a button.|
|Removable Cheek Pad It means that the cheek pads of the helmet are removable.|
|Washable Cheek Pad It means that the cheek pads are washable. It is important for hygiene.|
|Noise Inside The helmet's ability to reduce noise, to minimise the wind resistance and to encourage ventilation inside the helmet was assessed in a wind tunnel at a simulated riding speed of 100 km/h. The helmet was fitted on a mannequin designed for acoustic measurement. The mannequin was equipped with a specially designed microphone placed inside one of the mannequin's pinnas (ears). The wind resistance was measured using the force plate which is part of the wind tunnel and the ventilation was measured by measuring the pressure drop on the face and crown areas of the mannequin.||94.1 dBA / 100km/h|
|Ventilation||13.1 over 17.5|
|Aerodynamics||6.8 over 10|
|Vertical Field of View||6.1 over 7.5|
|Visor Wind Proof||10 over 10|
