Description

In 1990, Arthur Liao invested 350 Euros and started building helmets in a house under 600 square feet with one employee. That vision grew into a 330,000 sq ft factory producing more than 2 million helmets a year — with a dedicated North American warehouse in Chicago, Illinois serving riders across the US and Canada. Built and refined in-house. Start Your Journey. Helmets, jackets, pants, and gloves — LS2 builds gear for every type of rider, from daily commutes to track days. As an authorized LS2 dealer, every order comes with genuine product and real support behind it. LS2's AREM technology has stood up to harsh and rigorous lab testing — proven to keep you and your head safe. A built-in, drop down sunshield on a DOT and ECE standard platform all built into an affordable full motorcycle helmet? The LS2 Stream crushes the competition with its factory-direct cost. Sizes range from X-Small to 2X-Large. The shell is constructed out of Thermoplastic Technology (HPTT). Meets or exceeds DOT FMVSS 218 and ECE 22.05 standard. "A Class" Polycarbonate shield is optically correct, scratch and UV resistant. Pinlock ready shield included in the box. Quick change shield system built into the helmet. This helmet also includes a built-in sun shield. The Stream uses a quick release chin strap for a secure fit. The fully adjustable, multiport, dynamic, flow through ventilation with channeled EPS to keep you cool.

    • Incredible helmet at twice the price Incredible helmet at twice the price
Size: Medium Color: White
Review Image by Ian
I've owned a few helmets in the 15 or so years I've been riding, none of them top-shelf, some cheap, but most around the $300 price point. Then I got this helmet... the styling, features, build quality, materials and fit are on par with anything I've had that costs 3x or more. First, the technicals. I'm a medium in most brands, intermediate oval (given the choice), and prefer the way SHOEI fits over Arai. This LS2 fits as good as any I've had in the past. Nice and snug, no slop when I shake my head, my ears don't bend in half when I put the helmet on, and no noticeable pain points after a decent ride. I bought it in white, the pictures show the decals as black and red, but there is no red on the helmet I received. That aside, the quality is impressive, you can find plenty of YouTube reviews for details but the gist is that nothing about this helmet feels "cheap". Now the style. Sure it's subjective, but this thing looks badass. Most helmets are either obnoxiously aggressive or look like something grandpa wears on his two-wheeled RV. This helmet strikes a balance between the two, confident without being annoying, aside from the four "LS2" logos begging for attention from every angle. The only gripe I have with this helmet is the lack of a detent on the clear visor between fully closed and fully open. I'm used to having an extra "click" that keeps the shield open just a crack to allow for extra ventilation on hot days. But the integrated sun visor makes this more of a nit-pick than anything. ... show more

    • Great choice
Size: Medium Color: Black Red
Great looking helmet. According to the chart I was a 54” but ordered up to a medium. Head fits great. Padding on the cheeks are tight and squish my face but was told move it around some and it will relax over time. Was going to send it back for a large but kept and worked with the cheek foam. Fits good and has indents to mount helmet speakers in. I went with the Lexington G2P. Sounds great and fit perfect. The drop down lenses work great in the sun. Not quite sure yet on the air flow as it was 91 outside and my head was a little sweaty after riding 3 hours. ... show more

    • Gorgeous helmet, but pretty round.
This helmet is stunning. It feels super well built. The speaker cut outs are in kind of a weird spot, but they fit my 45mm JBL Cardo speakers well enough. The drop down visor is fine, but doesn't really matter to me as I have prescription glasses with transitions. The main visor is either open or close, there is no in between. That's strange. Unfortunately, this helmet didn't fit my head. The chin guard is too far inward and while it was a beautiful quilt to it, it also rubbed against my chin. Most helmets rub my chin a little, especially while talking, but this one was rough. The chin guard also sat too high up and exposed my chin. The chin strap is a quick release and is fantastic. Every helmet should be this way. I didn't get to ride with this helmet to test wind noise or vent usefulness, but it looks made well so I'm sure it was fine. Beautiful helmet that unfortunately just didn't work with my more long-oval head. ... show more

    • Solid 4.5 Stars.
Size: Large Color: Matte Black
I really like this helmet. Is it perfect? No, but pretty darn close. It was time to replace the Shoei RF-200 from 1991. The padding was disintegrating and not replaceable. Enter some research for affordable full face helmets. I kept seeing LS2 pop up on the lists of decent helmets at affordable prices. While pursuing AZ, I came upon the Stream in the amazon warehouse for a really good price. I figured I would give it a go. All I Can say is wow. One of the things I have issues with the Shoei is with my glasses, it always seems to push in on the earpieces causing discomfort. This helmet is very comfortable and has cut outs for glasses. I love the flip down sun visor built into it. I do have to hunt around for the lever to put it up or down but it's not terrible. The fit is very snug and I have to remove my glasses first to put he helmet on, there just isn't enough room to leave them on. The face shield has in pinlock and is easily removable. Is it an $800 Shoei? No, but it's probably 90% there for 1/5 the cost. The true test of the helmet is how well it protects you in a crash, something I hope never to have to test. But based on what I have read and experienced with the LS2, I recommend it as an affordable helmet. ... show more

    • Comfortable helmet
Size: X-Large Color: White
Was looking for a new helmet and found this L2 Stream. I liked to look and that it has an internal second sun visor. The helmet is very comfortable and fits perfectly. The sun visor is great and ventilation works very well. This helmet is a great value for the price.

    • Tight Fit, Cheap Parts
Size: Large Color: Matte Black
These Helmets run small. I used their size chart and ordered a large, I also have three other large motorcycle helmets and they fit me perfectly, but when I tried this on it is very snug, which I guess is okay if you want your face looking al squished up. The way the Helmet is designed allows only your eyes cheeks and nose to be seen, again my other helmets at least allow others to recognize you. The front of the helmet is so close to your mouth and nose you can hear yourself breath even with the shields open and directs your breath right up your face causing you to sweat Workmanship wise there are loose threads hanging off the stitching, another part that was supposed to be sewn in pulled out on one side unattached. The drop down inside goggle does not match the rubber supporting piece that it is supposed to fit against, the rubber is is off center, alot.. The mouthpiece vent is made of the thinnest cheapest piece of plastic I've ever seen, if you literally push it a little too hard it will snap off and break. The Helmet looks and feels like if you accidentally drop it the thing will split apart, my other Helmets I own are built solidly and sold for about the same price. The quick release chin snap is also made of cheap plastic and will not last long.I would not buy this helmet again, and pray if I'm ever in an accident that it protects me and just doesn't fall apart. ... show more
