Arai CT-Z Helmet
Arai introduced the CT-Z to their open-face helmet line after digesting years of real world rider feedback from their XC-RAM helmet. The XC-RAM was an incredibly successful helmet that provided exceptional value and convenience to riders. The Arai CT-Z uses the XC-RAM as a foundation and adds another level of convenience. Arai’s main objective for the CT-Z helmet is to provide riders with an open-face helmet that improved their experience riding into the sun without limiting ventilation, aerodynamics, or face shield functionality. Arai doesn’t change for the sake of change. They change to improve. The CT-Z is a nice improvement to Arai's helmet line.

From a positioning standpoint the CT-Z, in our opinion, is the most technically advanced, best venting, and most protective open face helmet we've seen anybody do so far. Obviously, it stands on the shoulders of all the Arai technology that we know goes into their full face helmets and really produces a phenomenal, top quality product.
I mean you're looking at north of $500 for an open face helmet. Pause and digest that. That's exactly what I said.
Now, if we really think about it, though, there's a lot here. Before I walk into all of the guts, let's talk about fitment. Typically, we see Arai helmets to be intermediate oval in a lot of cases. Their open face helmets tend to be slightly rounder, so I'm going to call it a neutral oval. If you have that long, pronounced, signet-q or profile type head shape this helmet's not going to work for you.
Also, from a weight standpoint it is Snell 2010. It's D.O.T. It's using the C.L.C. construction which is the same super protective composite outer shell that we see in the Vector 2. It came in three pounds seven ounces for a medium, so relatively light as well - still under three and a half pounds. Nice touch there from Arai.
I have my silver graphic in front of me, or silver colorway. Let's walk into the nuances here. Remember, the CT-Z is going to be the replacement for the XC Ram which is the more beefed up technical open face helmet. A step backwards from the CT-Z would be really the Arai XC which is a little bit more basic in its construction.
The first thing you're going to see that we haven't seen on an open face from Arai yet is going to be the peak. It's a refined version of the peak that we see on the XD-4 helmet. So, it's going to be aerodynamic. It's not going to buffer.
I mean this helmet is really designed for more of a touring riding style. Anybody can wear it. A scooter rider could wear it. I hate to pigeonhole a helmet. Really, they think that most helmets, most riders are going to be riding it in that position.
You see the way everything flows, the way the vents are set up, the way the peak is set up. It's going to be aerodynamic. Also, even with this rear spoiler to create a little bit of downforce it's not necessarily a helmet you're going to be rocking in that position.
You have your peak. Your peak is fully removable. It also has some range of motion in it as well. This is really done to reduce glare, you know, in place of a pair of sunglasses or a sun visor. It's meant to break away.
These are plastic bolts that are meant to shear off. Remember, any time you hang something on a helmet it could be considered a sail and outside of wind. If you were to go down you want this to break away and shear off as soon as possible. You don't want it to catch and create any undue stress on your neck.
Also, there are side pods here that have been streamlined versus the last version of the XC Ram. So, everything's a little bit tighter. It's a little bit more aerodynamic. And, if you took the peak off these pods would just go right into the helmet and you'd have a nice clean line here on the side as well.
Also, I'm going to flip it upside down and you're going to see that we have a black tape on the inside of this visor. That's anti-glare. It's the same type of an idea that you'd get from eye black like when you're playing sports. You put that there and you're not going to get any reflectivity down.
Notice we're using a high quality Arai shield. It comes up. It seats really nicely underneath that peak. And, there's a slight locking mechanism here on the side. You also have a good solid seal around.
One of the things that I really like about this helmet... We might as well move on to ventilation. We've talked about shell. We've talked about some of the things that are glaring at you in the face. A lot of ventilation. Remember, you're open face. You always have the magic of being able to put your face shield up.
A lot of people love that. The face shield down you have these brow vents. Arai does brow vents versus doing chimney vents up here because this is an impact prone area, and when you have to drill those vents in it weakens the shell. What they do is they create these brow vents as part of the shield. Again, it's the R and D that goes into the cost.
The nice part is you have these big scoops that channel the air. They don't just shoot you in the forehead. They actually channel it, and it comes out back here right along your temple.
So, you have that temporal artery that runs down along the back side of your ear. Especially from some of you guys that are doing long rides in hotter climates, if you can cool the blood flow you can cool yourself. It's dramatic how much that makes a difference. You get that air flow onto the artery that's cooling an area that's typically a really hot spot on your head as opposed to just shooting yourself in the forehead. Keep that in mind.
When we move up to the main ventilation scheme you're going to see the same horseshoe venting that we see in the Corsair V. Again, one of the tech things that they said we're going to steal because it's just super effective, but you're going to see some nuance changes to it.
We have our big cowls. Each one has a 10 millimeter vent hole below it, a 10 millimeter hole in the front, in the middle, open and close, 10 millimeter hole in the back. But, then we also have an open and closeable venturi vent that lives under here. What you're going to get is that high speed air flow going over the helmet creates a vacuum back here. Two intakes, and then we have an exhaust in the back here. That exhaust is going to extract warm moist air from your head and pull it out of the back of the helmet at speed.
Now, thinking along the lines of venturi, when you get this vacuum back here it creates what we call the Z coefficient which wants to pull your helmet up and off of your head. By creating downforce with this it's a fixed spoiler. It's not the fully movable spoiler that we see on the Corsair V, but you don't need it because your riding position isn't as aggressive with this helmet. Again, a nice feature here that's going to give you better stability at speed.
One of the cool things, and you're probably already wondering when I'm going to talk about it, is Anthony I've seen this vent before. I know this Arai vent. Why is it backwards on your sample?
Wrong. It's not backwards as an accident. It's a backwards on purpose. It is the same vent that we see on something like a Corsair V.
It's turned backwards because Arai knows that when you wear a helmet like this in most cases an upright position, in a lot of cases on a touring bike you're going to have a windscreen. A windscreen creates air flow. It comes up. It's going to swirl. It's going to create some turbulence around the head.
If this was faced forward in the open position it would create just a little bit too much noise. It's actually optimized to work with the type of air flow that's going to come over a helmet knowing that you're not in the tuck behind a tiny windscreen bubble. You're actually probably sitting upright working within the confines of a larger windscreen on your bike.
So, again, that's all wind tunnel testing. That's the juice that you get by investing in the Arai R and D.
A couple of other winglets down here, these are functional. These winglets are functional. They are also going to be for stability. They're extractors. You're getting additional airflow that comes out of the helmet, but they're also positioned and machined and shaped in a way that's not going to add to any turbulence. It's actually going to help the helmet be stable at speed.
Notice we have our nice ridge here, our energy absorbing ridge that Arai does. You know, it creates that circle on top of your head and it gives that ripple that's going to almost bounce some of the energy back. You want all of the energy in a crash situation to be contained within the shell of the helmet and the E.P.S. It's an energy management system at the end of the day.
Moving into the guts of the CT-Z, and again getting into some of the creature comforts and protective schemes, we are playing off the D.N.A. of the XC Ram. But, again, there's a lot going on here. We still have our vented neck roll that's going to have air comes down and now vents through the bottom. We're going to have a solidly all encompassing area that's going to interface with your head and neck.
Non-removable neck roll here in the back, but we do have a changed cheek pad style. When I pull one of these cheek pads out you're going to notice it's using the new facial contour system, or F.C.S., from Arai which is the second generation. The top layer of this cheek pad has a 5 millimeter removable panel. So, without having to buy a new set of cheek pads you can actually make them fit a little bit bigger which is a nice touch.
We saw that, I think, for the first time on the RX-Q. But, the new F.C.S. uses different densities of foam. It has a more aggressive contour to it. And, it actually creates a better seal and better comfort along the jawline and down creating kind of that seamless effect against the side of your face.
I'm going to actually stick it on my head up here. You can see right in here the way that this would touch my face, the way that it would come out, it's actually a much more ergonomic feel, and it's going to be a bit quieter as well. Remember, everything's removable.
The interior of the Arai, you know it's super premium. It's called Dry-Cool. It's washable. You can run it under water. It's anti-microbial. It's wicking. It's meant to keep you cool. I might as well gut this bad boy while I'm standing here.
Here's my other cheek pad system. Notice there's no snaps. The way it goes in is with tension, and it locks in from the front. Again, Arai prefers to do it that way. I like the fact less snaps. Snaps break over time, and they can wear out.
As I pull it open you're going to see I have my... Avoiding my neck roll here, and I'm moving up to my comfort liner. It's a 3D comfort liner with cutouts for all of the areas that are going to have a vent near them. Comfort liner's 3D, and notice that there are these pockets here, pockets along the outside.
You might ask yourself why there's a pocket covering that pad. It's another area that allows you to tune the helmet. It's going to be intermediate to neutral oval. If you have a really round head you also on either side can remove up to 5 millimeters of padding on the side.
The reason why they cover it is so that just for normal wear and tear it's not going to automatically start removing that pad. They want to kind of protect the seam, and if you want to remove it you can.
Just notice the way that that's done - high quality, Dry-Cool, big openings along the top, and you have four connection points with snaps. These two you'll never feel, and these two are spread out far enough that they're going to be away from these areas in the front of your head.
Let's take a shot of the interior of the helmet really quickly as well. You're going to see seven holes, seven 10 millimeter holes in a reverse horseshoe fashion that are really going to... That's the interior and exterior extraction points for the air flow coming through the Arai CT-Z, which actually does come in a bunch of other colorways as well.
Remember, if you're an XC Ram user, this is a nice step forward in both function, venting, styling. There's a lot you can do here.
A lot of different colors available as well. This is silver. There's the matte black. It's meant to be muted. It's a bit more of a toned down rider that we typically see go for the CT-Z or an XC Ram.
