The Alpinestars SM7 Blaster helmet is engineered for off-road racing and demanding powersports use, combining advanced impact protection, efficient ventilation, comfort, and aerodynamic performance. This White/Blue/Red helmet is offered in size XS and features a multi-layer composite shell made from fiberglass, carbon, and aramid fiber. The material blend is designed to help dissipate impact forces while supporting sliding performance, energy absorption, stability, and long-term durability. Its streamlined shell profile reduces external load points and promotes controlled deflection during an impact, helping limit the transfer of force to the rider’s head, neck, and spinal column.
The SM7 uses 20 individual ventilation ports, including 13 intake ports and 7 exhaust ports, to promote consistent airflow through the helmet. Removable, washable interior fabrics feature antimicrobial treatment, while the adjustable A-Head system allows the top pad to be customized for rider preference. Interchangeable 3D foam cheek pads are available across shell sizes and include an emergency extraction system, a hydration tube channel, and compatibility with optional replacement cheek pads. Integrated channels and ear recesses support hydration systems and communication equipment, making the helmet suitable for extended off-road riding and racing applications.
Protection features include Alpinestars PLASMA technology integrated into the lower side pads to improve shock absorption near the collarbone area. The Visor Detaching System is designed to release the visor when impact energy exceeds 15 Joules, helping reduce potential weaknesses associated with fixed visor anchoring. The removable chin strap cover, 25 mm nylon strap, and stainless steel double-D rings provide a secure and serviceable retention system. The crown and neck pads are elastically connected to assist with oblique impact management. This manufacturer product is supplied by Alpinestars under model SM7 and manufacturer/vendor part number 8301627-2217-XS.
