LS2 Stream II Full-Face Helmet with SunShield – Gloss Fury Black/Red (X-Small) | ECE 22.06

Overview

The LS2 Stream II is built for riders who prioritize style, comfort, and performance without paying a premium. Its sleek, aerodynamic silhouette sits on LS2’s Kinetic Polymer Alloy (KPA) shell, a high-tech blend that combines nanotechnology with aramid fibers and premium polymer. The result is a shell that manages energy efficiently while maintaining flexibility, contributing to a responsive, confidence-inspiring ride.

Designed to address rotational forces in real-world riding, the Stream II uses Advanced Rotational Energy Management Technology (AREM) to align with current safety standards. A rear spoiler helps create dynamic airflow through the helmet, supporting cooling at highway speeds and during spirited rides. Inside, a plush, well-engineered interior includes 3D laser-cut cheek pads and a removable liner with a flex-crown comfort system, delivering a comfortable fit that’s easy to refresh after long days on the road.

Core construction and protection

• Kinetic Polymer Alloy (KPA) shell blends strength with flexible energy management for everyday riding and sport riding alike.
• AREM rotational energy management meets contemporary safety standards for reduced rotational impact risk.
• Three shell sizes and five energy-absorbing EPS liners enable a precise, customizable fit.
• Optically correct Class A polycarbonate shield; Pinlock-ready fog control paired with a ships-with-clear-shield setup.
• DOT approved and FMVSS 218 compliant for broad road-use confidence.

Comfort, fit, and daily use

Inside the Stream II, comfort is a priority. The combination of 3D laser-cut foam in the cheek pads and a removable liner with flex-crown system makes it easy to keep the interior fresh. The intermediate oval shape aims to balance consistency with a snug feel across a range of head sizes.

• Removable, washable liner and flexible crown provide a refined fit and easy maintenance.
• Cheek pads use laser-cut precision for a supportive, comfortable profile during long rides.

Visibility and shield options

The shield is designed to be optically precise and compatible with fog-control solutions. This model ships with a clear shield and is Pinlock-ready, with an optional tinted shield available to suit sunny conditions.

• Pinlock-ready shield systems help reduce fog and improve visibility in variable conditions.
• Optional tinted shield (sold separately) for bright light riding.

Ventilation and ride experience

A rear spoiler supports flow-through ventilation, promoting steady air movement through the helmet. Combine that with a snug interior and you may experience a cooler, more composed ride at highway speeds or in winding roads.

Fit, standards, and use cases

With an intermediate oval fit, the Stream II aims to deliver reliable comfort across a variety of head shapes.
