RST Moto S-1 CE Leather PantsThe S-1 CE Leather pants were designed for both practicality and style. These full grain leather pants feature a fixed mesh lining and 4 way stretch for comfort. CE Level 1 knee and CE Level 2 hip armor are included for impact protection in these CE certified Class AAA The highest level of certification a piece of motorcycle apparel can achieve for abrasion resistance is CE Level AAA, as defined by the EN 17092-2:2020 standard. This rating is typically associated with high-performance riding gear, such as race suits, designed for the extreme conditions of track and high-speed road riding. The testing protocol for AAA-rated garments is significantly more stringent, reflecting the higher risks associated with these activities.During the Darmstadt abrasion test, the materials in Zone 1 of a AAA-rated garment are subjected to a much higher rotational speed of approximately 707.4 rpm. This simulates a slide on a concrete surface at a road speed of approximately 75 mph (120 km/h). The material passes the test if it does not develop a hole larger than 5mm in any direction after the abrasion. This demanding requirement provides riders with the highest level of assurance that their gear is built to withstand the intense forces of a high-speed slide, offering critical protection when it is needed most. To earn the final rating, the garment must also pass rigorous standards for tear resistance, seam strength, the impact protection performance of the included armor and additional factors. pants.
