Description

Move naturally through motocross and off-road riding with the SX-1 Plasma Knee Protector, combining Nucleon PLASMA impact protection with a ventilated frame and Dual Gear System (DGS) that follows knee movement while keeping protection positioned.

Key Features

• Highly Comfortable: The Nucleon PLASMA knee protector is designed for multi-directional pliability, the protector molds to the knee for a close fit, effectively dissipating impact energy to deliver reliable protection.
• Dual Density Co-Injected Frame for Support and Unrivalled Comfort: Engineered with a scooped lower extension made from a soft polymeric blend to avoid any pressure points associated with a hard edge from occurring as a result of the boot pushing against the protector. The same scooped design is also applied to the upper extension, preventing the protector from digging into the skin and causing discomfort while riding.
• Controlled Natural Movement: Featuring the Dual Gear System (DGS) where both the upper and lower frames have integrated gear profiles that ensure a smooth hinge function to promote the natural articulation of the knee.
• Ergonomic Frames with Versatile Sizing: The ergonomically sculpted frames of the SX-1 PLASMA Knee Protector feature strategically positioned rigid and flexible over-injected shells, providing a secure yet adaptive fit for a wide range of leg sizes.
• Patella System Protection: The Patella System is engineered to offer full coverage of the knee cup regardless of the degree of extension while the rigid outer Patella System shell prevents injuries from handlebar strikes.

Protection

Nucleon PLASMA Knee Protector (EN 1621-1:2012) - CE Level 1

Construction

Nucleon PLASMA element
The Nucleon PLASMA element is constructed from a bio-based viscoelastic impact-absorbing compound with 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. The low-profile PLASMA geometry is developed to compress and extend with movement while supporting airflow through its channeled and highly-perforated design.

Lightweight knee protection
The knee protector features a lightweight construction with extensive protective coverage.

Ergonomic polymer frames
The upper and lower frames are constructed from a high-performance polymer for optimized flexibility and strength, with excellent weight-saving properties and a slim ergonomic design.

Integrated dual pivot hinge system
The upper and lower frames feature an integrated dual pivot hinge system that follows the natural movement of the knee and keeps the protector well positioned while riding.

Dual strap closure system
The dual strap closure system features a hook-and-loop closure with snap-fit buckles for easy on and off and a personalized, secure fit.

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.
