Alpinestars SM7 Core Red

✅ Design & Purpose

• The SM7 Core is built specifically for off-road / motocross racing. Alpinestars+1

• It features an aerodynamic composite shell that’s streamlined and free of protruding features that could create weak points on impact. MX Rider+2SpazCycle+2

• The shell uses a composite construction (fiberglass, carbon, and Aramid fiber) to balance protection, energy dissipation, and light weight. Alpinestars SpA+2Alpinestars+2

🛡️ Safety & Protection Features

• The helmet is engineered to deflect and dissipate impact forces, reducing the risk of head, neck, or spinal injury. The curved shell helps direct forces away from the head. Alpinestars SpA+1

• It incorporates proprietary PLASMA-technology in the side pads around the shell edge to absorb shock — especially useful for impacts near the collarbone area. Alpinestars+1

• A patented visor-detachment system automatically detaches the visor from the shell if an impact exceeds ~15 Joules — lowering the chance of rotational injuries or helmet damage from the visor anchor. Alpinestars+1

• Internal padding and liner: includes a multi-density EPS liner and a 3D-foam comfort liner (with antimicrobial treatment) that is removable and washable, contributing to comfort and hygiene. bobscycle.com+2MX Rider+2

🌬️ Comfort & Practical Features

• Ventilation: The helmet has 20 individual air ports (13 intake + 7 exhaust, excluding eye port) for excellent airflow — useful during intense off-road riding or hot conditions. Alpinestars+2MotoRacingShop.com+2

• Fit customization: There are 6 consumer sizes (XS–XXL), and the helmet comes in multiple shell sizes so each size uses an optimally shaped shell. This improves both comfort and safety. Alpinestars SpA+1

• Adjustable fit system: The helmet uses Alpinestars’ A-Head Fitment System, which lets you adjust the angle and height of how the helmet sits for a more functional, stable fit. Alpinestars+1

• Hydration & communication ready: Integrated channels on both sides allow for hydration systems, and there are recesses in the EPS liner to accommodate speaker installation for intercom or communication systems. bobscycle.com+1

• Removable / replaceable cheek pads: Cheek pads are interchangeable (and available in different thicknesses) to fine-tune comfort and fit. Alpinestars+1

📐 Size & Weight / Certification

• The helmet meets ECE 22.06 and DOT homologation standards. MX Rider+1

• For a medium-sized helmet: weight is about 1280 g (ECE) / 1340 g (DOT) — relatively light for a composite-shell off-road helmet. MX Rider+1

🎯 Who It’s Good For

This helmet is ideal if you:

• Ride off-road, motocross, supermoto or perform any high-intensity dirt / trail / enduro riding.

• Value top-level protection (impact dissipation, rotational-impact mitigation, built-in safety systems).

• Want a helmet that balances comfort, ventilation and practicality (ventilation, hydration / comm-system ready, adjustable fit).

• Prefer a lightweight and aerodynamic helmet for high-speed or technical terrain.
