Alpinestars – RK-7 Plasma Knee Brace

With a slim ergonomic design offering a high level of off-road performance and comfort during dynamic movement, the RK-7 PLASMA Knee Brace has been engineered to provide superior knee support, while still being lightweight, breathable, comfortable, and protective. This knee brace features a free-floating Nucleon PLASMA knee protector encased in an innovative asymmetric fiber reinforced frame construction for enhanced levels of rigidity.

• This brace provides optimal structural integrity, rigidity and comfort, 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 knee cups are constructed with a polyurethane outer shell backed with a Nucleon PLASMA Knee protector for the optimum blend of impact protection, flexibility and scratch resistance.

• The replaceable strategically positioned upper and lower patella extensions ensure maximum coverage regardless of the flexion or extension angles.

• The extremely stable, slim-design four-point hinge system perfectly follows the articulation of the knee while the extension stops, which are available in a range from 0 to 30 degrees, 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.

• The Nucleon PLASMA Knee protector is constructed from USDA certified bio-based eco-friendly and sustainable impact absorbing material.

• Soft-touch thermoformed padding ensures the highest levels of rider comfort while keeping the knee brace securely in position. Replaceable as a spare part.

• Soft-touch thermoformed condyle padding comes in different thicknesses for a customized fit. Replaceable as a spare part.

• Nucleon PLASMA embedded into the shin padding for additional protection.

• Equipped with padded X-straps backed with a non-slip material to ensure the knee brace remains securely in position while riding.

• X-straps are profiled to avoid pinching the back of the knee when fully flexed.

• High tensile strength buckles are robust while still being flexible for easy strapping and adaptivity.

• Upper and lower buckles are easily locked into the closed position by a keyhole snapping system.

• Easily exchangeable extension stops (0, 5, 10, 15, 20, 25 and 30 degrees). Replaceable (as spare parts).
