Alpinestars 2027 S-M7 Blaster MX Helmet Black Grey Yellow Fluo

Description

The S-M7 is an advanced MX helmet developed for off-road racing, balancing lightweight performance, high airflow and long-ride comfort for riders pushing hard on track or trail.
Its aerodynamic composite shell and race-focused protection architecture are paired with Alpinestars’ A-Head fit system and integrated PLASMA side protection for confident, precise impact management when it matters most.

Key Features

• Ventilation layout: 20 intake and exhaust ports help drive steady airflow through the helmet to support cooling comfort during hard off-road riding.
• Removable liner: The 3D foam comfort liner with antimicrobial treatment helps maintain a fresher feel and makes post-ride cleaning more practical.
• Cheek pad customization: Genuine replacement cheek pads in multiple thicknesses let riders fine-tune the interior fit for improved hold and comfort.
• Eject removal readiness: Designed to accommodate an Eject Removal System, the helmet supports added race-day practicality when quick removal matters.
• Weight balance: A lightweight race build helps reduce neck fatigue and keeps the helmet feeling agile over longer motos.
• Hydration routing: Integrated side channels make it easier to route a hydration system for endurance-focused riding and racing.
