Description

Built for dynamic motocross and off-road riding, the Rk-7 Plasma Knee Braces combine knee support with natural movement through a four-point hinge system, helping you stay supported and comfortable as you move on the bike.

Key Features

• 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.

Protection

RK-7 PLASMA Knee Brace with Nucleon PLASMA Knee Protector (EN 1621-1:2012) - CE Level 1
Nucleon PLASMA Shin Padding

Construction

Nucleon PLASMA compound and geometry
The Nucleon PLASMA element is constructed from a bio-based viscoelastic impact-absorbing compound containing no less than 25% bio-based content, molded into a precision-engineered geometry. The PLASMA material dissipates impact energy and significantly reduces transmitted forces through controlled material response, while the low-profile PLASMA geometry is developed to compress and extend with movement and support airflow through its channeled, highly perforated design.

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

Thermoformed condyle padding
Soft-touch thermoformed condyle padding is available in different thicknesses for a customized fit and is replaceable as a spare part.

Nucleon PLASMA shin padding
Nucleon PLASMA is embedded in the shin padding for additional protection.

Padded non-slip X-straps
Padded X-straps are backed with non-slip material to keep the knee brace securely in position while riding and are profiled to avoid pinching the back of the knee when fully flexed.

Keyhole snapping buckle system
High tensile strength buckles are robust yet flexible for easy strapping and adaptability, with a keyhole snapping system that allows the upper and lower buckles to be easily locked in the closed position.

Exchangeable extension stops
The extension stops are easily exchangeable, available in 0, 5, 10, 15, 20, 25 and 30 degrees, and replaceable as spare parts.

Innovative impact absorbing protection that is elastic, forgiving, and moves with the natural movement of the body

Alpinestars Nucleon Plasma Protector, Red Perforated Flexible Armor for MTB Impact Protection and Breathability.

Breathability

The innovative structural design allows the protector to be slim and to have a high level of breathability, as well as flexibility, due to the high percentage of perforation attributed to the "M" shaped design.

Comfort

The inner side of certain protectors are laminated with a smooth fabric which provides a soft and comfortable feeling. The fabric adds durability and prevents possible tearing of the viscoelastic material.

Adaptive

The compound, combined with the 3D engineered structure, provides a very flexible and adaptive platform. The "M-shaped" structural design maximizes the area of protection while at the same time provides superior adaptivity.
