Alpinestars S-M5 Action 2 Bright Red Blue Glossy 3017

The Alpinestars S-M5 motocross helmet is designed to deliver top-level protection and comfort for MX riders. Featuring an innovative construction and advanced technologies, this helmet is the perfect choice for riders seeking safety and performance in one lightweight package.

The outer shell of the S-M5 is crafted from impact-resistant thermoplastic material and is available in three anatomical shell sizes. Combined with three unique EPS liner sizes, this results in six available sizes for optimal fit and maximum protection. The multi-density EPS liner ensures superior impact absorption by strategically placing the right density where needed most.

Equipped with a patented visor release system, the S-M5 ensures that the visor detaches with a predetermined amount of force, regardless of the impact angle. This enhances safety, while the specially designed chin bar profile minimizes the risk of collarbone injuries.

Ventilation is a key feature of the S-M5. Multiple air intake and exhaust ports provide maximum airflow and heat transfer, even during intense rides. The visor is designed to channel air directly into the ventilation ports, significantly enhancing rider comfort.

For oblique impacts, the S-M5 features a specially designed inner surface with a low-friction coating to minimize rotational forces.

Weighing just 1,350 grams, the Alpinestars S-M5 is lightweight, comfortable, and ready for any challenge. This helmet offers everything a motocross rider needs.
