LS2 Helmets Valiant II Modular Helmet - 180 Flip Modular Protection

In this review the LS2 Valiant II modular helmet is evaluated as a versatile option for riders who want the protection of a full-face with the convenience of a flip-front. The single biggest reason to consider the Valiant II is its 180-degree flip modular design combined with a lightweight, aerospace-grade shell that balances impact protection and ease of use, making it a strong choice for commuters and touring riders who switch between closed and open-face riding without carrying two helmets.

Key Features

• Aerospace-grade KPA shell: The Kinetic Polymer Alloy shell offers a lightweight construction with advanced impact energy management for better protection without excess weight.
• 180-degree flip modular design: The chin bar transforms smoothly from full-face to open-face, making it practical for stops, communication, and short urban runs.
• Twin Shield System: The cable-operated drop-down sun visor provides on-the-fly glare control so riders can quickly adapt to changing light conditions.
• Advanced ventilation: Adjustable intake and exhaust ports let the rider manage airflow and cabin climate for comfort on longer rides and warm days.
• DOT / FMVSS 218 compliant: Meets the regulatory safety standard expected in this market, offering reassurance about baseline crash protection.

Who It's For

The Valiant II is aimed at riders who need a single helmet that covers multiple situations: commuters who want a ventilated, comfortable helmet for daily use, touring riders who value a light shell and easy sun visor, and those who like the convenience of a modular flip for quick stops or talking with a passenger. The combination of an aerodynamic, small-profile chin bar and two shell sizes helps keep bulk down for extended wear.

Riders who need an ultra-quiet, custom-fit race helmet or those who prefer a dedicated full-face for track use should look elsewhere; some customers report the fit runs small or the cheek pads feel tight, so anyone between sizes should try it on or size up where possible.

Pros & Cons

Pros

• High-quality, lightweight KPA shell that balances impact resistance and low weight for comfort on long rides.
• Very versatile 180-degree flip modular front that converts between full-face and open-face quickly.
• Useful Twin Shield System sun visor and adjustable vents improve daily usability and comfort in varied light and weather.
• DOT / FMVSS 218 compliance gives a baseline safety assurance for road use.

Cons

• Fit can run small for some riders, with a few reporting tighter cheek pads that may require trying different sizes.
• Modular designs typically have more moving parts than a fixed full-face, which can mean additional maintenance over time.

Specifications
