Alpinestars Knee Guards
PRODUCT INFO
The Alpinestars RK-1 Plasma Knee Braces are built for off-road riders who demand stability, protection, and natural movement. Designed for motocross and enduro use, they help reduce the risk of common knee injuries while maintaining all-day comfort. As a result, riders can push harder with greater confidence.
Sold as a pair, these knee braces combine a lightweight hybrid frame with strong structural support. The integration of Nucleon Plasma impact protection ensures effective shock absorption without restricting movement. At the same time, the slim profile fits comfortably inside riding gear.
Protection remains a key focus. The RK-1 braces are engineered to support major knee ligaments, including the ACL, PCL, MCL, and LCL. In addition, triple-segmented knee cups and self-centering patella protection maintain consistent coverage through the full range of motion.
