Alpinestars RK-7 Plasma Knee Braces — XL, Black

RK-7 Plasma knee braces combine a slim, ergonomic profile with high off-road performance and comfort for dynamic movement.

The free-floating Nucleon Plasma knee protector is encased in an asymmetric, fiber-reinforced frame to increase rigidity while remaining lightweight and breathable.

• Replaceable polyurethane outer knee cups backed with Nucleon Plasma for impact dispersion, flexibility and scratch resistance.
• Strategically positioned upper and lower patella extensions ensure coverage through full flexion and extension.
• Extremely stable four-point hinge system follows natural knee articulation; exchangeable extension stops from 0° to 30° allow precise opening-angle limits.
• Stainless-steel hinge bushings feature anti-oxidation treatment for long-term durability.

Comfort features include soft-touch thermoformed padding, varying-thickness condyle padding for a customized fit, and Nucleon Plasma embedded into shin padding for added protection. Padded X-straps backed with non-slip material keep the brace secure without pinching behind the knee, and high-tensile buckles lock with a keyhole snapping system for easy fastening.
