ALPINESTARS SM5 RASH HELMET
The Alpinestars SM5 Rash Helmet is meticulously designed to provide motocross riders with a high level of safety, comfort, and performance. Every element of the helmet has been purposefully developed to meet the intense demands of off-road riding, making it a trusted companion on the track or trail.
The lightweight construction of the SM5 Helmet begins with a thermo-injected outer shell made from a specialized polymer blend. This shell is engineered with varying thicknesses strategically placed across key areas to optimize both impact resistance and weight distribution. The result is a helmet that offers robust protection without the added weight, reducing rider fatigue and improving overall control during extended or aggressive riding sessions.
Enhancing its protective capabilities, the SM5 incorporates a five-density EPS (Expanded Polystyrene) liner. This innovative liner uses different foam densities in specific zones to absorb and dissipate impact energy more efficiently. By ensuring the right density in the right area, the SM5 delivers improved shock absorption and reduces the risk of head injuries in the event of a crash.
In addition to its advanced safety features, the SM5 is designed for rider comfort. It features a soft, removable, and washable interior liner with moisture-wicking properties, helping to keep the helmet dry and fresh throughout the ride. Strategically placed ventilation ports provide consistent airflow, enhancing breathability and keeping the rider cool in hot or physically demanding conditions.
The SM5 Helmet represents a thoughtful balance of protection, weight, and comfort—qualities that are essential for serious motocross riders. From its smart shell design to its multi-density impact liner, every detail is engineered for performance and safety. Whether you’re racing competitively or enjoying off-road trails, the SM5 delivers the confidence and comfort needed for every ride.
