Sistema Modular Helmet Review
Bought this helmet for long distance riding (I have worn a half helmet for the past 40 years, so this was a departure). Was impressed with the weight and features, coupled with the price. Unfortunately, my first test ride detected a flaw in that the helmet's modular piece did not lock into place. Took it back to Cycle Gear, compared it to another helmet and we both determined this particular helmet indeed was defective. Cycle Gear manager exchanged it w/o issue. Performance-wise this helmet will meet my needs...it is comfortable, relatively quiet...yet, I can still hear my radio w/o cranking the volume, lightweight, and even looks pretty good.

Perfect After 1 Year & Still Like New
I love my Sedici Sistema High Visibility Helmet from Cycle Gear! Some reviewers claim there is wind noise. I'm older and half deaf so I can't hear the wind they speak of. And again other reviewers claim the chin lock and visor are hard to maneuver. I think most of the solid build quality is due to the fact that everything is sure and secure. Worth the extra effort in learning if nothing breaks. I aggressively pull the modular chin guard down with one hand and it's easy peasy. Locks right in... every time!

The visor hinge screw/bolts are great, once you learn how they work also. These bolts allow you to remove the visor for cleaning, or to easily replace a scratched visor. The visor itself takes the most learning. It is hard to lift but what I do is use the tab on the side to begin to lift... then I shift my efforts to the middle and raise it up. I do this with one hand and it's easy now that I know what to do. Going down is a snap so once again you must develop your own style to make it all work. Once you do, it's perfect! I'd buy this again... in a heartbeat. So should you! Be sure when you first try it on... get a tight... almost uncomfortable fit. It will expand in a short time and as it stretches out, it will perfectly fit your head.

I very strongly recommend the high visibility color. I say this for two reasons. One is they say cars cant see bikes and thats certainly true, as many experienced riders and even the teachers will tell you. The second reason is I notice cars do see me when wearing this color... and I never have a problem being seen. My last helmet was black and comparing the difference is extremely noticeable! When I wore my old black helmet, no one could see me. I thought it was personal. Now... wearing the high visibility color for over a year, cars give way even when they shouldn't. I now see it was never personal. Cars simply can't see bikers & I can't stress this enough. So don't hesitate to buy this helmet and the high visibility color... is an absolute must!

Good Value
I wasn't looking to buy a helmet at the time of purchase, and certainly not one as inexspensive as this one. The fit was just right on money, so I took a chance. This is my third modular helmet, and it is the quietest. Some say the noise level is high, but compared to other in this price point, it's much quieter. Still noisy enough to need earplugs on long rides though.
My only complaint is that the visor latch is very stiff. I'm afraid it might break, however, it seems to be getting easier with time

Great fit, poor construction quality
I purchased this helmet because I was looking to retire my existing modular helmet. It we as beginning to show it's age and I wanted to replace it with a high vis helmet due to my 50 mile round trip commute.

The only positive feedback I can give is that this helmet fits great and has a very conventient to access sunshade.

The helmet's build quality is pretty cheap and has started to show after only riding ~500 miles. A wire of some sort has poked out from between the shell and the interior padding and the cloth fabric that is between the padding and my melon has started to stretch and cause the helmet to slide when pulling down the chin bar.
Also important to know is that the visor is pretty difficult to open when riding and the protrusion to open it is offset to the left causing the visor to twist. The last complaint I can add is that the wind noise is much higher than any other modular helmet I've used.

PROS: Fit

CONS: Loud, Cheap build quality

BEST USES: Getting Shot Out Of, A Circus Cannon

the lite one
the helmet is very lite It seems to be all that it is advertised to be. the size seems to be on the small side of the scale. I ride every day so it should break in quickly.

Pretty good
Only after trying this one on, did I realize how heavy and restricting my previous helmet was. This one's padding is very snug, but far enough back on the jaw to not interfere with speaking, or causing discomfort when wearing for hours on end. And will say again: SOOOO light. Spent 4 hours on the highway without a sore neck or any wind buffeting.
Also appreciated how much space there was on the sides for adding in a bluetooth/speakers unit. Padding is easy to remove and put back together.
I've found the sun visor and flip-up easy to operate with one hand, and haven't had any malfunctions after 2 months of daily use.
Con: VERY LOUD. You can see the sizable gaps around the hinge that lets air through. I wear earplugs most of the time anyway, but they're practically a requirement if you're above 35mph.
If they were able to make it quieter, this would be a great helmet. I'm still overall happy with it.

PROS: Comfortable, Light

CONS: Noisy

BEST USES: Commuting, Keeping Skull Intact

Pretty Good Modular Helmet...
I bought this as an upgrade from my original Bilt Raptor Helmet, which was beginning to show it's daily ride wear and tear. This helmet fits very snugly, and is very comfortable, though when you lock the chinbar in place, it does compress your jaw a little bit (which is to be expected). The wind noise is high, but with earplugs or headphones it's not terrible. 8/10, would recommend.

PROS: good fit, Lightweight, Comfortable, Huge Sunshade

CONS: Wind Noise

BEST USES: Commuting, Street riding

Very good helmet
This is a great helmet at a great price. It was less than half the price of a Shoei. I don't understand the negative comments about this helmet being noisy. It is much quieter than my old Shoei modular helmet and quieter than an $800 Schuberth C3 modular helmet that I bought last year that was ranked as one of the quietest helmets made. The Shuberth vents created a bad whistling sound. This Sedici is not loud. I wear ear plugs but still I can tell that there is no annoying wind noise. I'm very happy with the fit as well. One of the best looking modular designs, too.

PROS: Comfortable And Quiet

CONS: Visor Operation

Good value comfortable fit
I bought the helmet on a whim not expecting to use it as my primary lid. I wore it on a 2,800 mile ride and found it to be comfortable, convenient and has better vision than my Shoei. The visor stays put at speed in 3 open positions. The pin lock feels secure.
It is a bit noisy, so I used ear plugs. It's actually quieter with the visor open than closed. With my windshield to nose level and visor open the helmet was the quietest. I did have to do a little modification on the Styrofoam liner to accommodate warring sun glasses. The flip down sun shades are a bit flimsy and flutter in the wind at speed.
I would recommend it as long as expectation are modest.

Great fitting helmet
Let me begin by saying that I have a narrow head, and this helmets fits me very well. I must have tried on 7 - 8 helmets, the Cycle Gear staff was awesome. I did purchase the high-viz version of this helmet. I love the additional drop down sun visor, which I use routinely. I would definitely buy this helmet again.

is it still dot cirtafide if you have the chin guard up?
A shopper on Mar 8, 2017
BEST ANSWER: i am sure it is still DOT approved with chin guard up because there are so many other helmets with no chin guard that are certified. more importantly, it would be very uncomfortable with guard up while riding because the guard will act like a sail.
I am looking at installing a Sena 20s on this helmet, are there speaker cutouts and how will the Sena unit effect the dropdown mechanism?
