The Alpinestars Nucleon KR-3 Back Protector is designed in three waist-to-shoulder dimensions to accommodate different body sizes. This large model features a single-injected lattice structure shell made from a high-performance polymeric material blend, providing flexibility and weight-saving properties while supporting impact absorption and airflow. Its ergonomic design promotes breathability for comfortable use in riding positions.
The central spine area incorporates Nucleon polyurethane foam for additional impact absorption, while the convex central hard-shell design is intended to provide protection for the spinal area. Horizontal flex grooves support an adaptive fit across riding positions. An adjustable rib protector adds side protection, and shoulder blade protective padding extensions help guard the acromion bones.
Fit adjustment features include a waist adjustment system, a slim vented kidney belt for position stability, and adjustable, detachable elastic shoulder straps with a snap-fit system. The Alpinestars Nucleon KR-3 Back Protector is compatible with Nucleon KR-C and Nucleon KR-TB protectors. Manufacturer part number: 6504718-13-L. Vendor part number: 6504718-13-L.
