LS2 Stream II Full-Face Motorcycle Helmet — Matte America Gray/Black Large, Integrated Sunshield & ECE/DOT Safety

The LS2 Stream II is a full-face motorcycle helmet with an internal drop-down sun visor, aerodynamic Kinetic Polymer Alloy shell, and certified impact performance for road use.

Designed for riders who want sport-inspired styling, practical sun protection, and modern safety features, the Stream II balances ventilation, comfort, and certified crash-management technology. It pairs a lightweight, shaped shell with managed rotational-energy design and multiple vents so you can ride longer with less fatigue and better vision in changing light.

How does the Stream II protect me on the road?

This helmet uses a high-tech Kinetic Polymer Alloy outer shell engineered for aerodynamic stability and impact resistance. Inside, a rotational energy management system designed to meet ECE 22.06 standards helps reduce transmitted rotational forces during an impact, while the EPS liner manages linear impact energy.

• Kinetic Polymer Alloy shell for sturdy, lightweight protection
• AREM rotational energy management aligned with ECE 22.06
• Multi-density EPS liner to absorb collision forces
• DOT/FMVS 218 compliance for U.S. road legality

Does it keep sunlight and glare under control?

The Stream II includes an integrated drop-down sunshield that you operate from the helmet’s exterior, giving you immediate glare reduction without swapping shields. Note that helmets are shipped with a clear outer shield; the images that show tinted shields are for illustration only.

• Built-in internal sun visor for quick protection from glare
• Clear outer shield included in the box; tinted shield shown optional
• Easy-access slider lets you change visor position while stopped
• Compatible with replacement or aftermarket face shields

How does ventilation and comfort perform on longer rides?

Airflow is routed through a series of intake and exhaust openings for continuous fresh-air circulation across the head and face. Combined with breathable interior liners and removable cheek pads, the ventilation system helps reduce heat buildup and keeps the liner fresh between cleanings.

• Dynamic flow-through ventilation to move air efficiently
• Removable, washable interior liners for hygiene and comfort
• Channeled EPS paths direct air across the head for cooling
• Sporty shell shape tuned for reduced wind noise at speed
