ALPINESTARS SM5 SOLID HELMET
The Alpinestars SM5 Solid Helmet is expertly crafted to meet the needs of motocross riders, offering a premium blend of safety, performance, and comfort. Designed with a strong focus on protection, this helmet integrates advanced materials and intelligent engineering to ensure reliable performance in demanding off-road environments.
At the core of the SM5 is a lightweight thermo-injected shell, built using a specially developed polymer blend. This shell is strategically engineered with varying thicknesses across key impact zones to provide the best balance between strength and weight. By reinforcing the helmet where it’s most needed while maintaining a lightweight design, the SM5 helps reduce rider fatigue and supports improved control, especially during extended or high-intensity rides.
To further enhance protection, the SM5 is equipped with a five-density EPS (Expanded Polystyrene) liner. This innovative liner is designed with different foam densities placed in critical areas of the helmet’s interior, ensuring optimal energy absorption in the event of an impact. Each layer of foam is positioned to respond effectively to different types of forces, maximizing safety without compromising comfort or fit.
The helmet’s interior also prioritizes rider comfort. It features a soft, removable, and washable liner made from moisture-wicking fabric that keeps the interior dry and fresh. Additionally, the SM5 incorporates a highly effective ventilation system, with multiple intake and exhaust ports that promote continuous airflow and help regulate temperature during intense activity.
Whether you’re competing on the motocross track or pushing your limits off-road, the SM5 Helmet delivers the protection and comfort you need to ride with confidence. With its lightweight design, advanced impact-absorbing structure, and rider-friendly features, it stands out as a dependable and high-performing helmet for serious motocross enthusiasts.
