AGV K3 SV Marco Simoncelli Replica Helmet

The AGV K3 SV Helmet builds on AGV's extensive experience in designing the Pista GP and Corsa helmets as well as the legacy of the original K3 helmet. An aerodynamic shell shape is optimized for stability and aggressive aesthetics and features an integrated, compact rear spoiler to reduce turbulence. The narrow chin bar is streamlined to help the helmet cut through the wind at high speeds, further increasing stability.

The AGV K3 SV helmet incorporates a drop-down sun visor, making the helmet a tour de force, aggressive street or touring helmet. The K3 is also communication-ready and features speaker pocket cut outs to minimize discomfort caused by Bluetooth speakers pressing into your ears. The AGV K-3 SV Helmet is an excellent choice for any rider who values sophisticated, modern design in a safe and feature-rich package.

AGV K3 SV Simoncelli Helmet 4.7 5 45 45
Limited visibility, ok airflow. Looks fresh though! Right off the bat, I'm here to tell you to save your pennies for the RF-1200 (check reviews on the Shoei RF-1200 and the X-14). From a purely aesthetic standpoint, the shape of the K3 SV, is pretty raw and aggressive, and the Simoncelli graphic kicks all kinds of a55. The helmet is quite comfortable, and the drop down visor is a nice addition, meaning you don't have to swap shields all the time. That said, the mechanism does add some weight to the helmet (see pic* but please note that the weight displayed is for a size ML with a Sena SMH-10 attached, seen in the pic). The helmet cuts through the wind nicely though, and I've experienced no lift, zero buffeting,even at triple digits, on track of course :D. There are some drawbacks, some minor, others kind of major. First, the v-shaped forehead vents. Pretty useless, and impossible to operate with a gloved hand. Overall, airflow is not great except for the one big vent that kicks air on the top of your head (thanks, I guess AGV? My bald spot needed cooling). The helmet also has a kind of a long, beak shape to it at the chin, that makes it hard to lane check without smacking your shoulder. My biggest gripe though is the visibility(or lack of) from the viewport. visibility is quite limited out the sides, but most annoyingly from the top, especially when riding a sportbike. I'm finding myself having to push up on the chin of the helmet frequently, to make it so that I can so the road ahead. Eeeek. The problem is compounded when I wear this helmet with my one piece leathers, that have an aerodynamic hump on the back. The hump limits how much I can push up on the helmet (bumps against the helmet) to be able to see while in a crouch. It seems all AGV needed to do was to raise the view port a few millimeters. But hey, at least this helmet doesn't blind me on sunny days (I'm looking at you, Shoei X-14). Overall, an ok helmet, that looks pretty cool, but I find it hard to recommend this over a great helmet like the Shoei RF-1200, for not a whole bunch more coin. April 19, 2016
EXCELLENT!!!! Great Helmet for the price. Great product. Awesome shipping. May 12, 2016
Great helmet, especially for the price. First off, let me start by saying how surprisingly quiet this helmet is. I ride an FZ-07 so wind is always a big issue, but even with all the vents open, I can comfortably ride at highway speeds with no earplugs. On one occasion I got up in the 100mph range (no comment on whether or not this was on the street...) and even then, the wind noise was manageable, but certainly loud. Others have mentioned that the diagonal vents aren't usable with gloves, but I beg to differ. As long as you pull them at the right angle, you can get them to open/close while riding, though it can be a bit tricky. The only complaint I have with this helmet is the weight. But that doesn't really surprise me, considering how much cheaper it is than, say, a Corsa or a Pista. I've certainly worn heavier. All in all, this is a great mid-range helmet. If you're looking for something better than the really cheap stuff, but you don't want to fork over the cash for a premium helmet, I would wholeheartedly recommend the K3 SV. May 9, 2016
This product has great features Its a good helmet for both track days and street riding April 26, 2016
The flip sun visor inside helmet for extra sun protection, I also purchased a smoke shield to replace the clear one that comes with helmet. Plenty of air flow , front lower vents always opened , no way to shut them closed, during a 45 degree morning ride felt a little cool, but did not bother me ,just fyi. Sizing true I have a 59cm dome, large fits me well , although the opening is a little narrow. Noise level does not bother me, I used to ride with no helmet for years. The main reason I purchased this helmet is the additional sun visor inside, makes my work commute into the sun both ways bearable. March 30, 2016
Great >$200 Helmet! Bought this helmet after trying it on at my local dealer, the sales guy claimed it was the breathing helmet he'dever used, and he was right. I live in San Antonio where the summers are absolutely brutal, and I wanted to feel the breeze as much as possible. The front vents are absolutely amazing, and provide plenty of air flow to keep me from being a sweaty mess. I bought a Size Large, and it's the larger of the two shells. It's kind of huge, but its still very light and comfy for longer rides. Drop down visor is the best feature helmets have seen in a long time, and this one worksgreat with the flip of a switch. I'm ventually going to install a bluetooth system so I'm glad the cutouts are very spacious. Again, the sales guy claims his fit with no problem, so I'm optimistic that he'll be 2 for 2. Great helmet all around, can't recommend highly enough! March 15, 2016
Awesome Day and Freeway Helmet This is my 1rst AGV helmet and I love it. I have been commuting with it all day and it felt really nice. I have a fairly small head so I got an XS but its still wasn't as tight fit as my Scorpion x710, but manageable. The greatest part was on the freeway, the helmet stayed on, no movement and the hawks-chin really made a difference at high speed compared to a regular helmet. Even at high speeds, the helmet stayed quite. The air vent placement is really good, especially on the chin, the air gets in but its not blowing on my lips getting them chapped as my other helmet does. The only thing I don't like is the visor. Every time I close it, it makes a very loud noise that hurts my ears. During night time there are too many reflections light bouncing of my eyes through it that it makes it harder to ride and stay focused on the road. Overall its a great helmet to be used during day time and high speed riding but its gonna take either a replacement visor or simply getting used to it to be able to ride at night. March 4, 2016
Premium helmet without the premium price tag--A great mid-level helmet My last helmet was a bargain bin Fulmer (which I actually loved), but I took a lil spill and needed a new one. Since I recently upgraded from a CBR250 to a 600RR, I felt I needed to upgrade to a more premium lid and this helmet fits the bill perfectly. When I measured my head, I was 22 inches, which according to the size chart was a medium-large, but when I tried it on, it felt too loose, so I swapped it for a medium small and it fits me super snug (in fact, I'm actually embarrassed at how loose my old helmet must have been!#. It takes me a little finagling to get my glasses in, but they don't press into my head or bow like they do in some helmets. Plus, I think that's mostly because I have very thin frames with a lot of bend to them. The helmet is very light, feels very solid, and I really like the "hawks bill" style. Coming from a sub $100 helmet to this one, I really like the extra features that make it feel more premium, such as the chin curtain #which really helps keep the air in/out), the "city"/cracked visor position, the quick change mech for swapping lenses, and the removable liner. Every helmet I saw all these features on was $300+! I also like that it is pre-cut for adding a com system, as that's something I plan to do eventually. The lens is very clear and good with not fogging; however, THE INTERNAL VISOR FOGS UP A LOT AND IF YOU HAVE GLASSES THEY WILL FOG UP EASILY IF THE MAIN SHIELD IS ALL THE WAY DOWN! The saving grace is the city position for the front visor, which allowed me to manage the condensation on the sun visor and my glasses, although this was not really possible at low speeds.
