Engineered for MX, Enduro, and off-road riding, the SM3 Helmet integrates advanced technologies and innovations designed to enhance ease of use, comfort, and impact protection.
  • Advanced Shell Construction: Features a thermo-injected shell with a specialized polymer blend and engineered thickness to provide the optimal balance of lightweight performance and high-impact protection (Weight: 1430g ECE / 1460g DOT).
  • Maximized Ventilation System: Engineered with 10 intake ports and seven exhaust ports to ensure high levels of heat transfer and constant airflow during intense riding.

  • Optimized shell thickness and structure in the chin area for superior impact performance, exceeding standard homologation requirements.
  • Engineered inner and outer surfaces designed to minimize the effects of oblique impacts.
