Alpinestars Honda S-M5 Motorcycle Helmets

The all-new Honda SM5 Helmet has been meticulously engineered to provide motocross riders with a premium balance of safety, protection, and comfort. Featuring a lightweight thermo-injected shell and a sophisticated 5-density EPS liner, this helmet is built to outperform the latest global safety standards.

Advanced Construction 

• Technologically Advanced Shell: Constructed from an impact-resistant thermoplastic blend with varying thickness for optimal weight-to-protection ratio.

• Anatomical Sizing: Available in three shell sizes and three individual EPS liner sizes.

• Precision Fit: Combined with specialized cheek padding, the system offers 6 unique sizes to ensure the best possible fitment for every rider.

• 5-Density EPS Liner: A 7-piece expanded polystyrene construction ensures the correct density is utilized in high-impact zones for superior energy absorption.

Key Features 

• Collarbone Protection: Features a specifically engineered raised area with soft padding to reduce force transmission to the collarbone.

• Patented Visor Release: The visor system is designed to release with a pre-determined force, regardless of the impact angle, preventing rotational snagging.

• Improved Ergonomics: The lower shell volume (Sizes M to 2XL) is 3% wider, making the helmet easier to put on and take off.

• Superior Impact Management: Outperforms ECE 22.06 standards with impact ratings up to 44% better than regular-speed thresholds.

• Redesigned Chin Bar: Sculpted base area with a flexible rubber compound and soft EPS extension to further mitigate collarbone injury risks.

• Maximized Ventilation: Multi-air inlets and exhaust ports work with the visor geometry to direct airflow and maximize heat exchange.

• Emergency Release System (ERS): Allows for safe and quick removal of cheek pads in the event of a crash.

• Hydration Ready: Integrated routing loops facilitate the easy mounting of hydration system hoses.

• Lightweight Performance: The ECE version weighs approximately 1,350 grams (Size M).

Protection & Safety Ratings 

• Rotational Force Mitigation: Engineered with a proprietary low-friction inner surface on the EPS liner to minimize the effects of oblique impacts.

• ECE 22.06 Compliance: Scores 70% under the new rotational oblique impact regulations—well below the maximum allowed limits.

• Global Certifications: Available in two versions: ECE R 22.06 and Dual ECE R 22.06/DOT.
