Designed specifically for off-road racing enthusiasts, the Alpinestars SM7 Dasher helmet combines advanced safety features with superior ventilation and lightweight comfort. Its aerodynamic composite shell ensures optimal impact protection while maintaining a streamlined profile that reduces drag and minimizes load points during impacts. The shell's curvature promotes energy deflection, helping to transfer impact forces away from the rider's head and neck, thereby enhancing safety in high-impact situations. Featuring a smooth, external design free of channels or protrusions, the SM7 supports maximum durability and performance in demanding racing environments.
The helmet's ultra-ventilated construction incorporates 20 individual intake and exhaust ports—13 intakes and 7 exhausts—promoting excellent airflow to keep riders cool during intense off-road activity. The ventilation system can be further customized with interchangeable cheek pads available in various thicknesses, ensuring a tailored fit for optimal comfort and stability. The cutaway section on the left side of the EPS allows seamless integration of communication systems, with earphone recesses on both sides facilitating speaker installation for connectivity during races or training sessions.
Constructed with removable, washable linings treated with antimicrobial fabrics, the SM7 offers hygienic, long-lasting comfort. The crown and neck pads are elastically connected for better impact management, especially in oblique impacts, while the adjustable top pad can be customized in height via the A-head system. The cheek pads, made from 3D foam, feature an emergency extraction system (ERS) and channels for hydration tube installation, with all pads being interchangeable across sizes for a personalized fit. The chin strap utilizes a 25 mm nylon strap with stainless steel DD rings and removable covers, supporting easy cleaning and adjustment. Integrated channels on both sides accommodate hydration systems, ensuring riders stay hydrated during intense off-road sessions.
The visor system is engineered for safety, featuring a detaching mechanism that releases when subjected to impact energies exceeding 15 Joules, preventing potential injuries. The visor's design ensures automatic detachment in case of high-impact forces from any direction, adding an extra layer of protection. Alpinestars' proprietary PLASMA technology is integrated into the side pads for high-performance shock absorption, significantly reducing injury risks by dissipating energy effectively. Overall, the SM7 Dasher helmet offers a comprehensive package of safety, comfort, and performance, making it an ideal choice for serious off-road racers seeking advanced protection and ventilation in a lightweight design.
