The helmet in general is not good. It has two serious disadvantages.

The first is that when putting it on/taking it off, it scratches your nose even if you try to wear it gently.
The second and even more serious is that a lot of air gets in even when the vents are closed, to the point that I consider it defective.

I have worn it less than 20 times but I will sell it because I will probably get sick. Bad choice.

We're talking about a helmet that costs €200. The build quality is perfect for its price along with all the features it has.

The upper air vent does not close completely, resulting in noise during trips at higher speeds. (above 80km/h). The lower air vent does not secure and opens by itself due to the airflow. If you want to constantly hear the wind, this is the helmet for you! The quality of the other materials is good for the money.

Very good helmet. It fits well, reduces the very annoying noise with the 125cc that I've pushed up to 100km. Just a bit, the pinlock somewhat touches the visor of the helmet and leaves a small watermark at that point, which is why I gave it 4 stars. Of course, when you wear the helmet it doesn't bother you, it's just a bit ugly when you see it :D

It produces a lot of aerodynamic noise, so you have to have the visor down, otherwise it whistles. Without the anti-fog membrane, the visor constantly gets foggy. The sun visor is useless for protecting against the sun, it's almost like you haven't put it on. If you have the clear visor (the transparent one) open, the wind hits you in the eyes, so you have to lower it as well...

Unacceptable, it gives you a headache from the excessive noise!!!!
And the worst part of it all is that at the well-known store where I bought it, because they have LS2 as a sponsor, they were saying the worst things about AGV and praising LS2.
I gave the helmet to a friend who has a scooter and needed a helmet, and I bought the K5.
Simply stay away

Owner of the ff800 here for 9 months. Quite good build quality and relatively comfortable on the head despite not fitting perfectly. Its pinlock is flawless, it doesn't fog up even in heavy rain, and the closure it has is extremely comfortable, as it easily fastens and unfastens without any difficulty, and also provides satisfactory ventilation. The only negative thing about it that I believe stands out is the noise inside the helmet due to the air, which starts even at 80 km/h. Maybe it's because I wear it on a hunched supersport motorcycle. However, this specific helmet is quite value for money.

I bought it 6 months ago from a motorcycle store, I bought 2 for myself and my wife, personally I'm not thrilled with it, I definitely wouldn't recommend it because it doesn't fit well and the quality is supermarket-level.

This is a very good helmet with a very good fit on the head, although it tightens a little on the cheeks (the helmet is not to blame for this). Perhaps a downside is the aerodynamic noise, but the pinlock is EXCEPTIONAL, it does not fog up even for a moment, even with the vents closed.

Former owner of Shoei
Now AGV K5 with all problems for its price of 280€. The clips of the visor constantly break. The sun visor falls off on its own. The rubber seals have been cut. The visor has become foggy and costs 45€ to replace. At night, I can't see... I bought LS2 Storm, incredible quality for its price always. I'll wait for time... for the rest.

I have had the helmet for a month and in my opinion, there is no better one for this price. It is simply amazing!!!!!

Owner of the ff800 here for 3 months now, I have to say that it is a very high-quality helmet. The materials they used seem to be durable. In terms of visibility, I have no problem, nor with the weight. The only negative is that at a certain speed, the helmet makes noise due to the air

Perfect for its price!! I highly recommend it! The only downsides are its weight, I would prefer it to be a bit lighter, and the aerodynamic noise above 100. Overall, it reminds me of more expensive and branded helmets.

Very good helmet for the money it costs.
Amazing sun visor, it's like wearing high-quality sunglasses.
Moderate aerodynamic noise, you will need the classic solutions (earplugs, Bluetooth headphones) for long and fast rides.
