Designed in a Black, Red, and Cool Gray color combination, these L\/XL knee guards feature an embedded Nucleon PLASMA knee protector within a highly ventilated, semi-rigid frame. The SX-1 Plasma is engineered to protect the knee during on-road, off-road, and recreational riding while maintaining a slim, ergonomic profile that fits comfortably beneath or over riding apparel. The manufacturer part number and vendor part number are both 6500326-1498-LXL.\u003cbr\u003eThe integrated Dual Gear System promotes smooth hinge operation and follows the natural articulation of the knee as the rider moves. Dual-density co-injected frames use scooped upper and lower extensions to help eliminate pressure points and reduce the risk of the protector digging into the skin. Sculpted rigid and flexible over-injected shells provide an adaptive fit for a broad range of leg shapes, while the dual pivot hinge system helps keep the guards correctly positioned during active riding. The patella protection system provides complete knee cup coverage through the full range of extension, with a rigid outer shell designed to help protect against handlebar strikes and other direct impacts.\u003cbr\u003eUSDA Certified Biobased Nucleon PLASMA material provides multidirectional flexibility and a close, custom-feeling fit while helping dissipate impact energy. The upper and lower frames combine high-performance polymer strength with optimized flexibility for dependable protection without unnecessary bulk. A dual strap closure system with hook-and-loop adjustment and snap-fit buckles allows riders to personalize the fit and maintain a secure hold throughout the ride. The Alpinestars SX-1 Plasma Knee Guards meet EN 1621-1:2012 Level 2 requirements for knee protection, making them a practical protective upgrade for compatible motorcycle, motocross, enduro, and powersports riding gear. Select the L\/XL size for the intended fit range and wear the guards as part of a complete protective riding system.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eNucleon PLASMA Protection: USDA Certified Biobased viscoelastic material provides multidirectional pliability, a close fit, and effective impact-energy dissipation.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eDual-Density Co-Injected Frame: Scooped upper and lower frame extensions help reduce pressure points and prevent the protector from digging into the skin.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eDual Gear System: Integrated gear profiles support smooth hinge function and natural knee articulation while riding.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eErgonomic Adaptive Fit: Rigid and flexible over-injected shells accommodate a broad range of leg sizes and help maintain secure positioning.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003ePatella System Protection: Provides full knee cup coverage through all degrees of extension with a rigid outer shell to help resist handlebar impacts.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eLightweight Protective Coverage: High-performance polymer frames provide a balance of flexibility, strength, and extensive knee protection.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eLow-Profile Design: Slim ergonomic construction fits comfortably with compatible motorcycle and powersports riding apparel.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSecure Closure System: Dual hook-and-loop straps with snap-fit buckles allow personalized adjustment and reliable retention.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSafety Certification: Knee protector meets EN 1621-1:2012 Level 2 requirements.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eFit and Identification: L\/XL size, Alpinestars SX-1 Plasma model, manufacturer and vendor part number 6500326-1498-LXL.\u003c\/li\u003e\u003c\/ul\u003e","brand":"ALPINESTARS","offers":[{"title":"Default Title","offer_id":49389046857963,"sku":"27040812","price":129.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0611\/3882\/9547\/files\/5572903.png?v=1789043156","url":"https:\/\/ctracingservices.com\/products\/alpinestars-sx-1-plasma-knee-guards-black-red-cool-gray-l-xl-6500326-1498-lxl","provider":"Cascade Tire \u0026 Racing Services","version":"1.0","type":"link"}
