Alpinestars SM7 Dasher Motorcycle Helmet - Matte Black/White, Medium

The Alpinestars SM7 Dasher helmet is engineered specifically for off-road racing enthusiasts seeking superior impact protection combined with optimal ventilation and comfort. Its lightweight construction features a composite shell with an aerodynamic profile designed to minimize drag and enhance stability at high speeds. The smooth, streamlined shell is free of external channels and load points, promoting efficient energy transfer and reducing the risk of injury during impacts. The curved design further reduces friction on impact, helping to deflect forces away from the rider's head and neck, providing reliable protection in demanding off-road environments.

Equipped with 20 individual intake and exhaust ports—13 intakes and 7 exhausts—the helmet ensures maximum airflow, keeping riders cool and comfortable during intense activity. The ventilation system can be customized with interchangeable cheek pads of varying thicknesses, available in all shell sizes, allowing for a tailored fit. The helmet’s interior linings are removable and washable, treated with antimicrobial fabrics to maintain hygiene and freshness over time. The crown pad and neck pad are elastically connected to better manage oblique impacts, while the top pad is adjustable in height via the A-head system for a personalized fit.

Designed for communication needs, the SM7 features a cutaway section on the left side of the EPS to seamlessly accommodate intercom systems, with earphone recesses on both sides for speakers. The cheek pads incorporate an emergency extraction system (ERS) and channels for hydration tubes, enhancing safety and convenience. The chin strap is equipped with a 25 mm nylon strap, stainless steel DD rings, and removable covers for easy cleaning. Integrated channels on both sides of the helmet allow for hydration system installation, helping riders stay hydrated during long rides. The visor system employs a detaching mechanism that releases upon impact exceeding 15 Joules, providing enhanced impact protection regardless of impact direction. Additionally, PLASMA technology integrated into the side pads offers high-performance shock absorption, significantly reducing injury risk in critical contact areas, making the SM7 a versatile choice for serious off-road racers.
