Product Description

Alpinestars brings you the RK-7 Plasma Knee Braces. 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.

Designed to provide optimal structural integrity, rigidity and comfort, these braces help reduce the risk of injuries to key knee components, including the medial and lateral collateral ligaments, the anterior and posterior cruciate ligaments, and the lateral and medial meniscus. At the core of the design is a slim, highly stable four-point hinge system that closely follows the natural articulation of the knee, ensuring smooth and controlled movement. Adjustable extension stops, ranging from 0 to 30 degrees, allow riders to fine-tune the brace’s range of motion to suit their riding style and protection needs, while stainless-steel bushings with anti-oxidation treatment enhance long-term durability.

A standout feature of the RK-7 is its advanced impact protection system. Constructed with a durable polyurethane outer shell, the replaceable knee cups are backed with a Nucleon PLASMA knee protector for the optimum blend of impact protection, flexibility and scratch resistance.

Nucleon PLASMA is a viscoelastic material, derived from bio-based polymers, and is engineered to remain pliable in all directions while effectively dissipating impact forces. Strategically positioned, replaceable upper and lower patella extensions ensure maximum coverage across different riding positions, maintaining protection whether the knee is flexed or extended.

Comfort and customization are integral to the brace’s construction. Soft-touch thermoformed padding (replaceable as a spare part) ensures the highest levels of rider comfort while keeping the knee brace securely in position. Soft-touch thermoformed condyle padding (replaceable as a spare part) in varying thicknesses allows for personalized adjustment. Nucleon PLASMA is embedded into the shin padding for additional protection. The brace is secured with padded X-straps featuring a non-slip backing, designed to keep the brace firmly in place without causing discomfort. These straps are carefully profiled to prevent pinching behind the knee during full flexion, while high-strength upper and lower buckles and a keyhole snapping system ensure easy, reliable fastening. Features easily exchangeable extension stops (0, 5, 10, 15, 20, 25, and 30 degrees), allowing precise adjustment of knee movement limits, with all components fully replaceable as spare parts for long-term usability.

Certified to CE Level 1 under EN 1621-1:2012 standards, the RK-7 Plasma Knee Braces meet stringent safety requirements while maintaining a lightweight and ventilated design. Combining advanced materials, ergonomic engineering, and rider-focused adjustability, these braces provide dependable protection and all-day comfort for serious riders seeking confidence and control on every ride.
