Alpinestars SM7 Helmet - Solid Gloss White - XL (Part #8301426-2180-XL)

The Alpinestars SM7 helmet is designed specifically for off-road racing enthusiasts seeking optimal protection, ventilation, and comfort. Its lightweight construction combined with a supremely aerodynamic composite shell ensures excellent impact resistance while maintaining agility on the trail. The shell's curved design promotes reduced friction upon impact, facilitating energy deflection to protect the rider’s head, neck, and spine. The aerodynamic profile features a smooth, streamlined shape free of external channels or protrusions that could compromise structural integrity or act as load points during a crash.
Ventilation is a key feature of the SM7, equipped with 20 individual intake and exhaust ports—13 intakes and 7 exhausts—maximizing airflow to keep riders cool during intense off-road sessions. The helmet’s fit can be further tailored with interchangeable cheek pads available in various thicknesses, allowing for a customized feel that accommodates different head shapes and preferences. The helmet also includes a cutaway section on the left side of the EPS to seamlessly fit communication systems, with recesses on both sides for speakers, making it ideal for riders who rely on intercoms or other communication devices.
Constructed with removable, washable linings treated with antimicrobial fabrics, the SM7 offers hygiene and comfort for extended use. The crown and neck pads 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. Cheek pads feature 3D foam with an emergency extraction system (ERS) and a channel for hydration tube installation, with interchangeability across all sizes. The chin strap is fitted 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 the addition of a hydration system to keep riders hydrated during long rides.
The visor system is engineered for safety, featuring a detaching mechanism designed to release under impact energies over 15 Joules, preventing additional injury. Additionally, the helmet incorporates Alpinestars PLASMA technology in the side pads for high-performance shock absorption, significantly reducing injury risk in critical impact zones. Overall, the SM7 helmet offers a comprehensive package of protection, ventilation, and customization, making it an ideal choice for off-road racing professionals and enthusiasts alike.
