Alpinestars RK-1 Plasma Knee Braces

• Anatomically profiled for all forms of off-road riding, the RK-1 Plasma Knee Brace has been engineered to provide comfortable knee support while still being lightweight, breathable, and protective
• This knee brace features a Nucleon Plasma knee protector encased in an innovative hybrid frame construction, consisting of a flexible composite over-injected on a high-performance polymer blend to offer superb frame rigidity while still being flexible at the upper and lower strap areas

Key Features

• This brace provides optimal structural integrity and support while being ultra-lightweight and adaptive, and thus reduces the risk of sustaining injuries to the medial and lateral collateral ligament, the anterior and posterior cruciate ligament, and the lateral and medial meniscus
• The replaceable triple segmented knee cups are constructed with a polyurethane outer shell backed with a Nucleon Plasma protector for the optimum blend of impact protection, flexibility, and scratch resistance
• The self-centering knee cup and the strategically positioned upper and lower patella extensions ensure maximum coverage regardless of the flexion or extension angles
• The stable, slim-design four-point hinge system follows the articulation of the knee while the extension stops, which are available in a range from 0° to 30°, assist in setting the brace to the desired maximum opening angle
• The stainless-steel bushings in the four-point hinge system have an anti-oxidation treatment
• Nucleon Plasma is a viscoelastic material engineered from bio-based polymers and formed into a structure that is pliable in all directions while maintaining the ability to dissipate impact energies
• Lightweight and highly ventilated, the knee protector offers strong impact force dispersion and absorption while ensuring maximum coverage in all riding positions
