The Mag-9 is Bell's premiere open faced helmet debuted in 2012. 
The beauty of what Bell has done here in 2013 is they've
completely iterated on this helmet.  They made a few key updates, but the
big functionality and why we're calling it the Mag-9 Sena is that it now
has an OEM fitment, you can see right where my finger is, there's an OEM
fitment panel that allows you to integrate seamlessly with the SMH-10 Sena.

So, what Bell did was they went out to the marketplace, they did their
homework, they looked at Carta, they looked at Fit Sena, they looked at the
other Blue Tooth units that were A2DP, that were Blue Tooth 3.0, that were
functional, and usable, and they said, "Who is the best that we can
integrate with, that our Mag-9 open faced customer can really add that Blue
Tooth communicator, but seamlessly do it in a helmet in a very usable way?"
They ultimately selected Sena.

So, remember the Mag-9 is going to be the intermediate oval head shape.
It's a polycarbonate shell, multiple sizes; I think it's an extra small
through 2XL.  There's a lot going on here we're going to walk through some
of the nuances a little bit later in the video.  Let's start out with the
key changes, now remember as we go through this I would love to hear your
gut reaction on our YouTube channel, click right here, subscribe to us,
stay up to date with all of our latest gear reviews.

So, let's walk into the key changes.  The first major change, and again I'm
going to finish here with the install of our Sena unit.  First key change
is they change the lever on the drop down sun visor.  It's now a finger and
a thumb operation, very easy to use.  Remember drop down sun visor anti-
scratch, anti-fog, gives you the ability to not have to wear sunglasses if
you don't want to. Nice touch we've seen it a lot in different progressive
helmet manufacturers, and it was on the original version.  It's now much
easier to use.

Also, staying in that same vein of comfort and flexibility you know they
know, Bell knew that a lot of customers are wearing the open faced helmet
with sunglasses, and sometimes when you're cheek pads are a little bit more
dense near the top it becomes different depending on the type of sunglasses
you're wearing. So what Bell did is they took the top area of this cheek
pad and they tapered it and they made it a little bit less dense foam.  So,
whether you're wearing eyeglasses, or you're wearing sunglasses you're now
going to have an easier time of getting them into the Bell Mag 9 Sena and having
them work comfortably.

The other thing they did on the new Mag-9 is that they've given you an
increased range of motion on your external face shield.  So, this drops
down all the way. The previous Mag-9 used to come up to about there, and
depending on how you ride, and how it sits on your head sometimes you might
get it in the top end of your vision.  So, what Bell's done is they've
given you extra range of motion now to fully clear it from your field of
view, again a really nice touch.

Now moving past that, and remember the Bell Mag 9 comes with a peak, it's
fully removable, there are side pods, you can wear it without the peak, you
can wear it without the shield itself, it's completely configurable.

Let's get into the Sena functionality, and really I'll show you what the
unit looks like, and some of you out there I have a Sena myself, I wear a
Sena, it's very rugged.  In my opinion it's one of the most usable Blue
Tooth communicators on the market.  Really that's why I love that they've
chosen to work with Sena because it's extremely usable.  Remember, ten days
of standby, twelve hours of talk time, A2D which means you can forward and
reverse, play, pause, talk to Siri on an iPhone, multiple device
connectivity over Blue Tooth, so that means GPS, as well as iPhone, up to
four riders 900 meters.  Again, watch our full detailed breakdown on the

The Sena is a rock solid unit. But looking at the Sena and how it would
integrate with the Bell is that now what Bell has done is they've not only
changed the outer shell, but they've also changed the EPS to seamlessly
integrate.  What I'm going to do is show you how easy that is, and how
quickly it works.

So, what you have is this panel on the side, and remember five different
colors in the Mag-9, you also have a couple graphics available as well, and
it's right here on the left side underneath the lever, and you want it on
the left that's typically where Blue Tooth communicators go, because you
can keep your hand on the throttle.

So, as I use my thumbnail, that I've actually, that I bite my fingernails,
so let's see if I can get this off.  There we go.  I pull this door away,
and now I'm exposing a compartment that's perfectly suited for the Sena
unit, and you can even see the way it sits in there is slightly recessed.
The Sena's actually one of the bigger units, and for a lot of touring guys
they're okay with it, but if it sits fully off the Mag 9 Sena helmet you might get a
little bit of noise because it is a bigger unit, even though it is
aerodynamic, water resistant, you know it covers all of those bases.  By
slightly recessing it you're having a better chance to not create anything
external kind of extreme hanging of the helmet.  So again, you get a more
streamline air flow.

But what you have is you have the unit that would sit in there and recess
in but still leave enough room for the buttons, the connection port, you
know the jog dial here that again is one of the big selling features you
can also press, but behind that you're going to see that we have EPS cut
out. And what Bell's actually done, I'm going to go get my doughnut here,
is they've changed the EPS.  So, as I flip over from the top I'm going to
start to remove things, and again it's a good time to talk about the liner.
So, as I remove the liner out, remember anti-microbial microfiber, it's
wicking, the pockets around the ear are plenty cut out to handle the
seating unit, which has stereo speakers.

You can pull this bad boy out; you can pull out the entire liner.  It
actually has channels in it for the EPS.  I might as well just remove the
entire liner here, and remember intermediate oval head shape, and if you're
concerned about fit, remember we ship for free, exchange for free, no
restock fee if you need to send it back to us.  So, don't fret if you're
really curious about the sizing. But I'm going to remove my neck roll.
Here's my comfort liner, notice the cutouts they give you good air flow
through the EPS channel.

If you didn't notice there are two vents on top of the Mag-9, but as we get
into the guts here, I'm going to rotate this way, and you're going to see
around here on the side that where Sena would go we have this piece.  Can
you see that piece, if you can come in here really tight?  And what I can
do is I can put my finger in here and just quickly pop this piece right
out, and it has a pull tab at the top.  You can pull it from the top or the
bottom, but this is my pocket that's going to allow me to pull it out so I
can use the OEM fitment for the Sena SMH-10 Bell version.

So, once I pull the EPS piece out I can now and install my Sena, and again
I've removed the entire guts of the Mag 9 helmet, but really all you need to do
is remove that left side cheek pad.  What I want to do is pull everything
out and get it out of the way, but for you guys at home installing this you
don't have to go that far.

Now if I look at it, remember I have my cutout on the side, I know have my
cut out on the inside, OEM fitment, and what I'm going to do here is I'm
going to take my, really the female bracket here that has the connector,
that has the boom mic, that sits in this channel, and there's really only
one place it can go, and as I turn it this way I'm going to slide it up
from the outside, and you need to make sure to get it all the way in that
way you have room to install the Sena, and you can see it just flush mounts
right in there.  It completely closes that off, it completes the seal, and
now I have my connectors. And there's also that little screw hole you can
see it right to the left of the connection port, and you want to leave it
permanently installed, you want to make sure it's on their securely it
comes with a single screw and an Allen you just pop that bad boy right in.

Now what I can do is I can reach across, take my actual Sena unit, this is
the actual unit that you charge, this is what has all of the guts and
technology in it, slide it from the bottom down to the top it pops right
in, and it's that simple.  Recess mounted, completely installed inside, and
you'll notice I have my two speakers.  They're stereo speakers, they're
thick enough, and both sides of the helmet have plenty of room to where you
just snake these up, put the cheek pads back in, and you sit them in the
little pockets of the ears, and they kind of, they don't Velcro on, but
they have teeth to them so they kind of hold themselves in place.

Again, from front on you can see the low profile of the unit on the Bell Mag 9. And if I
turned to the side, you can also see again Bell being very thorough as they
typically are, you can see that I have my boom mic sits in a nice recessed
cut away from this EPS liner.  So, they've really thought through the
complete recipe for getting an OEM fitment on a Blue Tooth unit within
their helmet without having anything bulky, and remember there's voice
activation.  It's an adjustable boom, you put it where it needs to be. And
it's also going to be noise cancelling, so whether you're riding at speed
with it up, or with the face shield up or down you're going to have the
ability to have you're fully functional until.

Now, while I do have it in there I might as well leave it in.  I'm going to
let those speakers free float, because honestly placing them is the least
exciting part of the process, and it takes two seconds.  You can see the
interior liner, cut-aways, four vented channels, we have four exhausts in
the helmet, two intakes across the top you can see them with nice big pulls
so you can find them with a glove.

I mentioned the peak is removable, it's reconfigurable, it does have side
pods that go on there, remember it's a polycarb shell, multiple EPS sizes
that go up with the different sizes of the actual helmet itself, so
starting with extra small and going all the way up. And it's going to be
that intermediate oval head shape, which I did touch on, and remember that
means it should fit most people, but if you're curious you can always give
our gear geeks a shout out and talk through the sizing, and we're not going
to hurt you if you need to send it back.

You know other key things of note with the Mag-9, we saw it in 2012 be a
nice step forward from Bell. Now moving into 2013 you're getting the added
benefit of the seamless OEM interface with the Sena SMH-10, and remember
you can buy the Bell version, which is kind of comes with the housing
that's pre-integrated, or you can always buy that $40.00 piece if you
already own a Sena, and just buy that housing that sits on the back of it
and allows you to flush mount it right on.
