We will go over every aspect of the LS2 Stream II, such as its safety features, design, comfort, and performance. This article will help you figure out if the Stream II is the ideal helmet for you, whether you’re a beginner or an experienced rider. Let’s get started!
Safety Features and ECE 22.06 Certification
The LS2 FF320 Stream helmet is a wonderful pick because it is safe. It is certified under the ECE 22.06 standard, which is stricter than the ECE 22.05 standard. This standard tests helmets for rotating forces during collisions, which is a more realistic way to test them for real-life crashes. LS2 is all about keeping riders safe, and the Stream II can do that.
- Kinetic Polymer Alloy (KPA) Shell: Combines aramid fibers with a polymer for strong, flexible impact resistance.
- Two Shell Sizes: Covers XS-M and L-3XL, ensuring a proportional fit for better protection.
- Reflective Panels: Sewn into the neck skirt for improved visibility in low-light conditions.
- Glancing-Off Design: Reduces rotational forces to the brain during impacts.
The helmet’s exterior shell is made of a special material called Kinetic Polymer Alloy (KPA). It is made up of aramid fibers and a polymer. KPA is stronger than normal thermoplastics but not as expensive as fiberglass or carbon fiber. It keeps the helmet light while still protecting against collisions quite well. The Stream II comes in two shell sizes (XS-M and L-3XL), so it will suit a lot of different head sizes, which is very important for safety.
The helmet felt safe and solid , even at high speeds. Its design helps it bounce off blows, which makes the brain less likely to be harmed by rotational pressures. The fluorescent panels on the neck skirt also make it easier to see in the dark, which makes it safer to ride at night or in foggy conditions.
The LS2 Stream II offers a number of safety features, so it’s a fantastic choice for anyone who want to ride safely without spending a lot of money. This helmet will protect you no matter where you are driving, in the city or on the highway.
Outer Shell and Design
The LS2 Helmets Stream II Full Face Motorcycle Helmet’s outer shell is made from Kinetic Polymer Alloy (KPA), a material that balances durability, weight, and cost. Unlike basic thermoplastic shells, KPA includes tiny aramid fibers for added strength, making it a solid mid-range option. The helmet comes in two shell sizes, which keeps it proportional and sleek across the XS-3XL size range.
Here’s what makes the shell and design special:
- Material: KPA is stronger than thermoplastics but cheaper than fiberglass or carbon fiber.
- Two Shell Sizes: Keeps the helmet sleek and proportional from XS to 3XL.
- Finish Options:
- Solid colors like pearlescent white for a classic look.
- Graphics like ‘Racer Red/Blue’ for a bold, sporty vibe.
- Quality: Flawless graphics and high-quality plastics, with a minor chin vent imperfection noted.
The Stream II looks great. The “Racer Red/Blue” looks great, especially on sporty bikes. You can even choose solid hues like pearlescent white for a more classic, clean look. For a cheap helmet, the finish is great. The plastics are high quality, and the graphics are clear and bright. There was only one small fault , which was a slight imperfection at the chin vent. It didn’t effect how well it worked.
The aggressive look of the helmet is both useful and good-looking. It passes the ECE 22.06 “glancing-off” test, which implies it can take blows from a lot of various angles. The Stream II is a great deal for the money because it looks and feels like a high-end helmet, no matter what color or graphic you choose.
Weight and Aerodynamics
At 1,563g for a medium size, the LS2 Stream II is within LS2’s claimed weight of 1,500g ± 50g. This puts it in the same range as other ECE 22.06 helmets, like the HJC C10 and Arai Quantic (1,588g). While lighter helmets, such as the Shoei NXR2 (1,392g), exist, the Stream II’s weight is typical for its class and doesn’t feel heavy during use.
Key points:
- Weight Comparison:
- Shoei NXR2: 1,392g (lighter but pricier).
- Arai Quantic: 1,588g (slightly heavier).
- Aerodynamics: No drag on the BMW R1250GS or low-screened Honda VFR800.
- Comfort: Balanced weight distribution prevents neck strain.
Weight is only part of the equation—aerodynamics matter more for comfort. A helmet that catches the wind can strain your neck, even if it’s lightweight. The Stream II performs well here, with no noticeable drag on the BMW R1250GS or the low-screened Honda VFR800. Its streamlined shape makes it comfortable for long rides, even at highway speeds.
It never found that felt ‘too heavy’ when properly fitted. The Stream II’s balanced weight and aerodynamic design ensure it stays comfortable, whether you’re riding for an hour or a full day.
Ventilation System
The LS2 Stream II’s ventilation system is designed to keep you cool and comfortable. The chin vent has three settings: closed, part-open, and fully-open. It’s operated by a large button that’s easy to use with gloves, but the difference between part-open and fully-open is small. The vent also doesn’t close securely, which could let in a bit of water in heavy rain, depending on your bike’s windshield.
Here’s how it works:
- Chin Vent:
- Three settings: closed, part-open, fully-open.
- Large, glove-friendly button.
- Doesn’t close securely, risking minor water ingress in heavy rain.
- Top Vent:
- Three settings feeding two slots into EPS channels.
- Connects to two rear exhaust ports and one on each side (always open).
- Performance:
- Adequate for most conditions but struggles in extreme heat.
- Glasses-wearers may need to remove the nose guard and chin skirt to prevent fogging.
The top vent has the same three settings and feeds air through two slots into channels in the EPS inner shell. These channels connect to two large exhaust ports at the rear and one on each side, which are always open. The system works well but isn’t outstanding, especially for riders who wear glasses. We c an remove the nose guard and chin skirt to prevent visor fogging, which made the helmet draftier but improved airflow.
For most riding conditions, the ventilation is good enough, but it may not be ideal in very hot weather. Keeping the visor slightly open can help in summer, and the system performs better on bikes with minimal wind protection.
Visor and Sunshield
The LS2 Stream II’s visor mechanism is one of its best features. The central thumb tab makes it easy to open and close with either hand, and you can set it to any position, including a just-cracked setting for extra air. It locks securely when fully open and stays in place at high speeds. When closed, it seals tightly, preventing water leaks.
Here’s why it’s so impressive:
- Visor:
- Central thumb tab for easy one-handed operation.
- Adjustable to any position, including a just-cracked setting.
- Secure when fully open, no drop-down at speed.
- Watertight when closed.
- Easy to remove and reinstall for cleaning.
- Pinlock 70 MaxVision:
- Included fog-resistant insert.
- Early batches had fitting issues (resolved with replacements).
- Sunshield:
- Thumb-tab operated, removable.
- Useful in bright conditions but has a nose gap causing light leakage.
Removing the visor is simple—just pull and rotate—and reinstalling it is even easier. This makes cleaning quick and convenient. The helmet comes with a Pinlock 70 MaxVision insert, a fog-resistant lens that works well once installed. Some early batches had fitting issues, but LS2 quickly sent replacements, fixing the problem.

The drop-down sunshield is operated by a tab on the lower left side. It’s great for riding in bright sunlight, especially in spring or autumn when the sun is low. However, the gap between the sunshield’s cut-out and the nose lets in some light, which can be distracting. The sunshield is removable if you don’t need it.
Overall, the visor and sunshield are user-friendly and effective, making the Stream II a practical choice for all-day riding.
Comfort and Lining Inside
The Stream II’s hypoallergenic lining is soft, comfy, and can be taken out completely for easy washing. It feels lot nicer than you’d expect from a cheap helmet, which makes the experience even better. The reflective panels on the neck skirt make it easier to see, which is a wonderful safety feature.
The Stream II’s interior is designed for comfort and practicality:
- Hypoallergenic Lining:
- Soft and high-quality, feels premium.
- Fully removable and washable.
- Reflective Panels: In the neck skirt for visibility.
- Drawback: Forehead seam may cause discomfort after long rides (subjective).
There is a seam in the forehead area that can make uncomfortable after a few hours. This might not matter to everyone, since fit is different for everyone, but it’s worth checking when you try on the helmet. The liner is otherwise great, which adds to the helmet’s overall comfort.
Fastening Mechanism
The LS2 Stream II uses a micrometric ratchet fastener, which is standard for non-racing helmets. It’s easy to adjust and secure, even with gloves on, thanks to a flexible plastic pull-tab. This system is reliable and allows for a snug, customized fit every time you wear it.
Features:
- Easy to adjust and secure with gloves.
- Flexible plastic pull-tab for quick operation.
- Precise fit customization.
Fit and Personalization
The LS2 Stream II helmet may not fit everyone the same way, so always try it on before you buy it. Overall, we thought it was comfortable, however someone can felt quite pressure on forehead, perhaps from the seam in the lining. It helped to gently press down on the forehead area with a round spoon, but you should never cut a helmet to change it, as this can make it less safe.
Key points:
- Fit Experience:
- Comfortable overall but some forehead pressure noted.
- Forehead seam may bother some riders.
- Customization:
- Two shell sizes and cheek pad options.
- Gentle compression (e.g., with a spoon) can ease pressure points (avoid cutting).
A competent dealer can help you make sure the fit is right, and the Stream II comes in two shell sizes and has different cheek pad options for customization. Getting the fit just right is the most important thing you can do to be as comfortable and safe as possible.
Intercom Compatibility
The Stream II is designed for intercom use, with recesses in the EPS liner for speakers. I tested it with a Sena 50S, and the speakers fit comfortably without pressing on my ears. There’s no lip for clipping an intercom, but the side of the helmet has plenty of space for an adhesive mount, making it compatible with most systems.
Levels of Noise
You need to use earplugs with all motorcycle helmets, and the LS2 Stream II is no different. It is a little louder than others helmets, and the noise from the wind is most evident around the sides. But the noise isn’t too bad, and good earplugs help a lot. No matter what kind of helmet you have, you need earplugs for extended rides.

Alternatives to the LS2 Stream II
The sub-£150 ECE 22.06 helmet market is growing, but here are three alternatives to the LS2 Stream II:
The LS2 Stream II does well in the sub-£150 market, especially when compared to comparable helmets that have been certified by ECE 22.06. The HJC C10 is a good choice for riders on a budget at £89.99, but it doesn’t have some of the Stream II’s features, such the sunshield. The Scorpion Exo-391, which costs £89.99, is another choice, although it’s hard to compare them directly without a comprehensive evaluation.
The AGV K1 S Dundee costs £120.08 and has high-end style, but it might not be as good of a deal as the Stream II when it’s not on sale.
- HJC C10 (£89.99): The cheapest ECE 22.06 helmet we’ve tested, offering great value for budget riders.

Tips for Getting the Most Out of Your LS2 Stream II
- Proper Fit is Key: Make sure the helmet fits well by trying it on for a while to make sure it doesn’t put any strain on your head. If your forehead hurts, contact your dealer about changing the padding.
- Put in Earplugs: Always wear earplugs to block off wind noise and safeguard your hearing, especially on prolonged rides.
- Take care of the visor: To keep it from fogging up, clean it often and make sure the Pinlock insert is lined up correctly.
- Change the airflow: Try out the chin and top vents to see which ones let in the most air for the way you ride. Taking off the chin skirt can assist when it’s hot.
- Install an Intercom: If you want to utilize an intercom, pick one with an adhesive mount so that it will be easy to put up.
Real-World Performance
Testing the LS2 Stream II gave us a clear picture of its performance. A touring bike with a tall windshield, the helmet’s aerodynamics shone, with no drag or buffeting at high speeds.
The ventilation was sufficient for spring and autumn rides but needed the visor cracked open in warmer weather. On the VFR800, with its lower screen, the helmet still felt stable, though wind noise was slightly more noticeable.
The visor could perform a lot of things, which was impressive. We could simply change the Stream II to fit my needs, whether we required a fast blast of air or full rain protection.
The sunshield protected us on rides in the early morning, even though the light leak was a little annoying. Even though the seam on the forehead had a problem, the lining was so comfy that lengthy rides were fun. To fix the problem, we can made small modifications.
Who Is the LS2 Stream II For?
The LS2 Stream II is ideal for:
- New Riders: This helmet is a wonderful first helmet because it is cheap and has safety features.
- Commuters: For daily rides in different weather, the visor, sunshield, and intercom compatibility are great.
- Touring Riders: Its aerodynamics and comfort make it great for extended trips.
- Riders on a budget: You get high-end features without the high-end price.
You might wish to look into higher-end options if you want lightweight helmets or need the best ventilation. But the Stream II has everything most riders need at a far lower price.
