Your cart is empty.It’s hard to imagine just how good the LS2 Stream II full-face motorcycle helmet is. Style, features and performance that surpass helmets costing literally twice the price, this helmet is an out-of-the-park home run. It starts with an aerodynamic, sport styled shell made from LS2’s proprietary Kinetic Polymer Alloy (KPA). This high-tech material uses nanotechnology to blend microscopic aramid fibers with a high-end polymer. This blend allows for amazing energy managing performance with managed flexibility that absorbs energy without the ricochet effect of inferior materials. The Stream II meets the ECE 22.06 rotational energy management specifications using Advanced Rotational Energy Management Technology (AREM), another LS2 proprietary process. The rear spoiler allows for dynamic flow-through ventilation. The 3D laser cut foam in the cheek pads, removeable liner with special flex-crown comfort system is super comfortable and easy to keep fresh. 3 shells and 5 energy absorbing EPS liners make for a fit that is nothing short of amazing. The optically correct, Class A polycarbonate shield is Pinlock ready, for the ultimate in fog management (Pinlock sold separately). The overall finish and performance sets the Stream II at the forefront of full-face motorcycle helmets. Even those costing twice the price. Meets or exceeds ECE 22.06 and DOT FMVSS standards. Intermediate oval fit. DOT approved. Meets the FMVSS 218 Standard.

It’s a bit snug on my head but looks great. Hard to gauge how well it blocks out noise as I use headphones when I go on longer rides. It does fog up pretty bad in cooler weather. Waiting to see how the fogging does on warmer days.

My first helmet and I love it. Great color and features and comfort. A little heavy but you get used to it. With a colored visor it looks great. Only thing is the logos are quite big but the quality of materials used is great for the price. 6 months later and it still feels and smells new

I love the helmet. Looks great and fit well, however, it arrived broken. MxMegastore ships this helmet in its own packaging. It’s a thin box that does not provide protection for the helmet. The rear vent cover was broken off and was unable to be reattached properly due to broken plastic pegs. I would think since dropping your helmet is bad, letting it get thrown around in shipping while in a lightweight flimsy box is not the best way to ship it. I got a refund with no issues and am currently waiting to receive the new one from a different seller. Hopefully it is shipped in a more protective box. 2 stars for Mx MegastoreUpdate: I received the 2nd order from Powersports monkey. They shipped it in another box and included extra padding as shown in the pic. The helmet arrived in pristine condition. Thank you Powersports monkey! 5 stars for you.

This was not a good fit for me even though it's said to be the same size as my other helmets. My chin was sticking out of the helmet and it was extremely noise.

Fits perfectly, I always loved LS2 helmets. Can be a bit loud on the highway, but it’s comfortable. The piece of fabric under the chin and plastic above the nose make it feel a lot more secure and is better for the wind.Good visibility, looks awesome, and the drop down sun visor is great too 10/10.

Bought this because of the safety ratings. Got an RF-1400 not long after. This helmet is fine. Good for the price. To me its just as good if not as much or more comfortable and noise level as the RF-1400. However it does fog up real easy and the placement of the shield is very limited in comparison to the RF-1400, but it's a good helmet. When I bought the RF-1400 I laced the chin strap of the LS2 on the rear grab bar and it held at 70-80mph, I was expecting it to fly off and then have retrieve it but it stayed. Kudos.
