Advanced Thermoplastics with High Impact Resistance

LS2 modular helmets utilize advanced thermoplastic resins—specifically engineered polymers that offer an optimal balance of flexibility, rigidity, and shock absorption. These materials are injection-molded to precise tolerances, creating a shell that resists cracking and deformation during impact.

One of the key advantages of these thermoplastics is their ability to absorb and disperse energy across the helmet's surface, reducing the force transmitted to the rider’s head. Additionally, their lightweight composition significantly reduces neck strain, especially during extended rides. This makes them ideal for modular helmets, which are frequently used in both open-face and full-coverage configurations.

EPS Multi-Density Liner

The Expanded Polystyrene (EPS) multi-density liner is a cornerstone of modern helmet safety. This internal layer consists of strategically arranged foam zones with varying densities—softer on the inside for comfort and firmer on the outer edge for impact absorption.

During a collision, the EPS liner compresses progressively, absorbing kinetic energy and minimizing the peak force that reaches the skull. This multi-layered approach ensures effective protection across different types of impacts, whether glancing or direct. The precision engineering of the EPS liner in LS2 helmets meets or exceeds international safety standards, including ECE 22.06 and DOT certifications.

N9 and N10 Visors
