Description

All-Terrain Explorer From the roughest singletrack to urban blacktop, the MX-9 Adventure Mips gets you there safely in style. We've taken our MX-9 and added even more capability with an integrated no-fog, no-scratch clear shield. The shield flips up and leaves enough room for goggles in extreme conditions, or it can be removed completely. Conversely, the adjustable visor can be removed for a stealth street look. Mips protection, Velocity Flow ventilation, and a removable, washable, no-microbial liner round out a highly adaptable package. *The Marauder Blackout colorway ships with a second dark smoke shield. Availability, certification, and color may vary per region. If outside of the USA, please check with your authorized local dealer for more information.

I'm quite surprised how cheap this helmet is for what it is. Yes in your hands it feels a little heavier than some premium helmets. However, when you're wearing it, it's totally fine. I don't feel it heavy one bit. Using it with the goggles on my off-road dirtbike.

Able to use goggles with the face shield is dank. Also go pick up a GoPro mount from ā€œchin mountsā€ they work perfect.

Tight fit but decent quality
Size: Medium Color: Matte Black
A bit heavy, and didn't come with a 2nd tinted visor like Shoei does. They only had the flat black when I wanted a different style. But I guess it will have to work. The sun shield is a bit thin. Will have to see how it holds up.

Very Used Product Shipped
Size: Medium Color: Matte Black
Item came in used! packaging damaged, padding worn, item was most likely returned and not inspected. There is a reason something like this is usually purchased as NEW. I would expect the product to be new, or else I could get it for 100$ especially since its a safety product. Very disappointed, wasted my time. ... show more

Helmet is LOUD!
Size: Medium Color: White
So, let me start with some positives; helmet fits well and is comfortable right off the bat. Good vision and good air flow. The down side this helmet is the loudest full face I have ever owned. I don't even ride without ear plugs, its just too noisy. In fact I think my 3/4 helmet might be quieter. The other downside is there is no way to shut off the air flow so, if its cold then cold air flows around your head. This helmet might be best described as a summer helmet. I like the idea of the MIPS technology, but I wanted a quieter helmet for full face. ... show more

Potentially good helmet ruined by wind noise.
Size: Medium Color: Matte Black
I recently purchased this helmet as a replacement for my older Fox V1 that I use when riding my 300cc dual sport. For clarification, the Fox V1 is an open faced helmet used primarily for MX. The main reasons I wanted a replacement for that helmet are that it is fairly loud above about 40 / 45 mph. I do not mind that when riding solo, but when riding with others my communicator is of little use above those speeds. Secondary reasons for wanting a new helmet are that the peak (on the V1) has very little ventilation on the rear, so it blows around a bit above about 60 or 65 mph, and it would be nice to have a face shield when cruising at higher speeds. All the reviews I read / watched for the Bell MX-9 Adventure MIPS (say that three times fast) spoke very highly of this helmet, and a few mentioned that it has considerable wind noise. My assumption was that those statements meant it was loud for a closed-face helmet. For those considering purchasing this helmet, let me clarify that it is loud even compared to other open-faced helmets. According to the sizing chart I should have been a large, but People on the Internetā„¢ said to order it a size large so I did. This proved to be sage advice, and when it arrived the helmet fit well. I took this helmet for a test-ride, and was somewhat shocked to find that I could not even hear my bike above about 60 mph with the visor up. I put the visor down and still could not hear my bike above about 60 mph. I switched back to my V1, and went down the same roads at the same speeds. With the visor up on the MX-9, the V1 is noticeably more quiet. This is not great, but was not necessarily a deal breaker. After riding around with the V1 for a bit, I switched back to the MX-9. I confirmed that even with the visor down it was louder than the V1. This was a deal breaker. I was not too happy about that, because this helmet has some great things going for it: - Excellent field of vision - Relatively lightweight - Comfortable - Good ventilation - Looks good It's also quite affordable, and overall seems like great value for money. The problem is that all of the other features combined do not make up for the wind noise. There is simply no scenario in which a closed-face helmet should be louder than an open faced helmet. Should anybody from Bell somehow read this review: My guess as to the cause of the noise is that it is not so much an airflow issue as it is an aerodynamics issue. I noticed that I had substantial air flow across the backs of my ears (unusual, but pleasant when it is hot out). I also noticed that the location of the noise moved forward with the visor closed. I believe what is happening is that air is moving across the bottom of the chin bar, which is level or slightly higher than the bottom of my jaw, and being drawn up into the helmet at the jaw line. I suspect that this is causing one or more of the following effects: - an eddy at the top of the ear (so the air would move forward and swirl right in front of the ear opening) - a resonance / amplification of the noise due to the open area around the ears - I am somewhat doubtful of this as I did not notice any buffeting or beating (Helmholtz resonance) - air to move across the ears in an upward fashion that the ear is more sensitive to (the ear definitely seems to have a degree of directional sensitivity when it comes to wind noise) With the visor closed: - Opening and closing the mouth vent made almost no difference. - If I covered one of the forward vents (not the mouth vent) with my hand the noise was somewhat reduced. - If I put my hand flat against the bottom of the helmet below my ear it almost completely eliminated the noise. I suspect that lowering the bottom line of the helmet (and possibly lowering the reach of some of the internal padding), and probably a few other tweaks to the overall geometry, could greatly reduce the wind noise of this helmet. ... show more
