The Alpinestars SM7 Helmet in Core Gloss Red offers premier protection and ventilation for off-road racing enthusiasts. Designed with a lightweight yet durable composite shell, this helmet provides exceptional impact resistance while maintaining aerodynamic efficiency. Its smooth, streamlined profile minimizes external load points, reducing the risk of impact-related injuries and ensuring optimal energy transfer during collisions. The curvature of the shell promotes reduced friction upon impact, helping to deflect energy away from the rider's head and neck, while the integrated PLASMA technology at the lower shell edge enhances energy dissipation in the collarbone area, further safeguarding vital regions.
This helmet is equipped with 20 individual intake and exhaust ports—13 for air intake and 7 for exhaust—to maximize airflow and keep riders cool during intense activity. The ventilation system is complemented by removable, washable interior linings with antimicrobial treatment, ensuring comfort and hygiene over extended use. The fit is highly customizable with exchangeable cheek pads available in various thicknesses and sizes, allowing for a tailored fit that enhances safety and comfort. For communication needs, the SM7 features a cutaway section designed to seamlessly accommodate intercom systems, along with recesses for ear speakers. The internal padding includes a crown pad and neck pad elastically connected to manage oblique impacts effectively, while the top pad can be adjusted or removed thanks to the A-Head system.
Safety features extend to the visor attachment system, which is engineered to detach automatically when subjected to impact energies exceeding 15 Joules, preventing secondary injuries. The visor itself is designed for easy detachment, contributing to rapid helmet removal if necessary. The chin strap uses a 25mm nylon strap with stainless steel DD rings and removable covers for cleaning. Additionally, integrated channels on both sides of the helmet allow for hydration system installation, ensuring hydration during demanding off-road sessions. The SM7's construction combines innovative materials and design features to deliver a helmet that balances ventilation, protection, and comfort, making it an ideal choice for high-performance off-road racing.
