Cutting-edge technology for performance with the SX-1 Plasma knee protection from Alpinestars

Benefit from an advanced technical design thought for modern motocross.

Their semi-rigid, reinforced and ventilated frame not only offers excellent shock dissipation, but also promotes air circulation to limit heat build-up.

Their DGS (Dual Gear System) mechanism allows the knee to bend and extend fluidly, perfectly accompanying the rider's natural movements.

A strategic choice for those looking for reliable protection without compromising on agility.

FEATURES :

• Incorporates a Plasma knee protector inserted into a highly ventilated semi-rigid structure, providing superior impact protection, while the integrated Dual Gear System (DGS) promotes natural knee articulation.
• Made from a USDA certified bio-based viscoelastic material, molded into a flexible structure in all directions, while maintaining excellent ability to dissipate impact energy.
• Dual-density co-injected frame : A supportive structure that combines unmatched comfort and great adaptability. Its curved lower extension made of a soft polymer blend prevents pressure points caused by the boot pushing against the knee guard.
• The same curved design is used on the upper extension, which prevents the protector from digging into the skin and causing discomfort while riding.
• Controlled natural movement — DGS system : The upper and lower frames incorporate gear profiles providing smooth articulation that respects the natural movement of the knee.
• Incorporates over-injected rigid and flexible shells, strategically positioned to allow effective adaptation to a wide variety of body shapes.
• The patella system is designed to provide complete coverage of the kneecap, regardless of the degree of knee flexion, while the rigid external shell effectively protects against impacts, including handlebar strikes.
