The Alpinestars SM7 Core helmet in Gloss Red, size Small, is engineered for off-road racing and demanding riding conditions. Its advanced composite shell combines fiberglass, carbon, and aramid fibers to balance impact protection, force dissipation, sliding performance, energy absorption, stability, durability, ventilation, and comfort. The streamlined aerodynamic profile helps reduce friction during an impact while promoting efficient deflection and energy transfer away from the rider’s head, neck, and spinal column.
Feature: The helmet uses Alpinestars’ A-Head Fitment system, allowing the removable and adjustable top pad to be customized for a secure, comfortable fit. Replacement cheek pads are available in multiple thicknesses and can be exchanged across shell sizes for additional fit adjustment. The removable, hand-washable liners feature antimicrobial-treated fabrics, while the elastically connected crown and neck pads support oblique impact management.
Feature: Twenty ventilation ports, including 13 intake ports and 7 exhaust ports, provide substantial airflow through the helmet. Integrated channels accommodate a hydration system, and the cheek pads include a hydration tube passage. The helmet is also communication-system compatible, with a left-side EPS cutaway and speaker recesses on both sides for intercom installation.
Feature: The Visor Detaching System is designed to release the visor during impacts exceeding 15 joules, helping reduce weaknesses associated with fixed visor anchoring systems. Alpinestars PLASMA technology is integrated into the lower side pads to help absorb shock in the collar-bone area. The 25-millimeter nylon chin strap uses stainless steel double-D rings and removable covers for convenient cleaning. Emergency extraction system features are incorporated into the 3D foam cheek pads.
