Alpinestars SX-1 Plasma Knee Guards Black Red Gray

Experience superior impact protection and natural knee articulation with the Alpinestars SX-1 Plasma Knee Guards. Engineered for serious riders, these knee protectors combine advanced materials and innovative design to keep you safe and comfortable on every ride.

Description

The Alpinestars SX-1 Plasma Knee Guards are meticulously engineered to provide advanced motorcycle knee protection for riders demanding both safety and comfort. These innovative off-road knee guards integrate a Nucleon PLASMA protector within a highly ventilated, semi-rigid frame, ensuring exceptional impact absorption across a wide range of motion. The biobased viscoelastic material of the Nucleon PLASMA protector is designed for multi-directional pliability, molding to your knee for a close, secure fit that effectively dissipates impact energy.

The unique Dual Density Co-Injected Frame offers robust support without compromising comfort. Its scooped lower extension prevents pressure points from boots, while the upper extension avoids discomfort against the skin, allowing for extended wear. The integrated Dual Gear System (DGS) ensures the upper and lower frames move fluidly with your natural knee articulation, maintaining optimal protector positioning during dynamic riding.

Crafted from high-performance polymers, the frames balance flexibility and strength while remaining lightweight. With an EN 1621-1:2012 Level 1 protection rating, these MX knee protectors deliver reliable performance, making them an essential component of your riding gear. The slim, ergonomic design provides a low-profile fit, and the dual strap closure system allows for a personalized, secure fit, offering unparalleled impact protection knee guards for your adventures.
