LS2 Valiant II Modular Motorcycle Helmet - Lightweight Modular Shell

In this review the LS2 Valiant II is judged as a practical choice for riders who want the convenience of a flip-up modular helmet without a heavy touring helmet's bulk. The single biggest reason to consider the Valiant II is its combination of a lightweight, aerodynamic Kinetic Polymer Alloy shell and a slimmer chin bar mechanism that improves airflow and reduces weight. For riders who value a modern energy management shell and easy daytime convenience, this helmet delivers focused engineering rather than flashy extras.

Key Features

• KPA shell: The proprietary Kinetic Polymer Alloy shell blends microscopic aramid fibers into a polymer to offer penetration resistance with a bit of flexibility for energy dispersion.
• Lightweight construction: A lightweight shell helps reduce neck fatigue on longer rides and improves overall comfort for everyday use.
• Smaller chin bar mechanism: The newly designed flip mechanism is slimmer than the original, improving aerodynamics and reducing wind buffeting at speed.
• Modular 180-degree flip: The full-face chin bar flips up to a convenient modular position for quick stops, communication, and ventilation without removing the helmet.
• Two shell sizes: Multiple shell sizes allow a closer fit and smaller overall shell for typical head shapes, improving balance and comfort.

Who It's For

The LS2 Valiant II suits commuters and sport-touring riders who want modular convenience without sacrificing a modern energy-management shell. Its lighter KPA construction makes it a good match for riders who switch between city and highway speeds and who appreciate a smaller, more aerodynamic profile.

Riders who prioritize ultra-quiet operation, integrated electronics, or the absolute lightest race-oriented shells may want to compare other models. Those seeking full-face isolation for long high-speed tours should evaluate wind noise and visor sealing in person.

Pros & Cons

Pros

• Lightweight KPA shell offers a balance of penetration resistance and controlled flexibility for energy management.
• Slimmer chin bar mechanism improves aerodynamics compared with the original Valiant.
• Modular 180-degree flip provides quick convenience for stops and communication without helmet removal.
• Two shell sizes encourage a closer fit and smaller overall shell for better balance.

Cons

• Not marketed with integrated electronics or premium touring noise reduction, so buyers seeking those features should check fit and accessories.
