The Alpinestars RK-1 Plasma Knee Braces are specifically designed for all forms of off-road riding, providing a perfect combination of protection, comfort, and lightweight performance. These knee braces feature a Nucleon Plasma protector encased in an innovative hybrid frame construction that combines a flexible composite over-injected on a high-performance polymer blend, delivering excellent frame rigidity while maintaining flexibility at the upper and lower strap areas. This design ensures optimal structural integrity and support, significantly reducing the risk of injuries to the medial and lateral collateral ligaments, anterior and posterior cruciate ligaments, and the menisci. The braces incorporate replaceable triple segmented knee cups with a polyurethane outer shell backed by a Nucleon Plasma protector, offering a superior blend of impact absorption, flexibility, and scratch resistance. The self-centering knee cup and strategically placed upper and lower patella extensions provide maximum coverage regardless of the knee's flexion or extension, ensuring consistent protection during riding. Featuring a slim, four-point hinge system with anti-oxidation stainless-steel bushings, the braces follow the knee's articulation with extension stops adjustable from 0° to 30°, enabling customization of the maximum opening angle. Constructed from bio-based, eco-friendly materials, these braces emphasize sustainability without compromising strength or performance. The soft-touch thermoformed padding ensures rider comfort and secure fit, while four individual straps with non-slip backing keep the brace firmly in place. The central buckles utilize a convenient keyhole snapping system for easy locking, and soft-touch condyle padding in various thicknesses allows for a tailored fit. Lightweight and highly ventilated, the Alpinestars RK-1 Plasma Knee Braces excel at dispersing impact forces and maintaining maximum coverage in all riding positions, making them an essential safety gear for serious off-road enthusiasts.
