Alpinestars Yamaha S-M3 Motocross Helmet
The Alpinestars Yamaha S-M3 is a high-performance motocross helmet designed to offer superior protection while remaining lightweight. Its modern shell construction, combined with ECE 22.06 certification, ensures reliable safety during off-road use. The lightweight outer shell made of impact-resistant thermoplastic and the multi-density EPS inner shell support effective distribution of impact forces and improved energy absorption. An integrated ventilation system with multiple inlets and outlets ensures a continuous airflow, while the aerodynamically optimized design further enhances cooling. The helmet is complemented by a patented peak release system and an emergency release system with removable cheek pads for safe helmet removal in the event of an impact. The Yamaha S-M3 is ideal for ambitious motocross and off-road riders who value safety, comfort, and performance.
