The ALPINESTARS Nucleon KR-3 Back Protector is designed in three waist-to-shoulder dimensions to cover a range of body sizes. This small protector features a single-injected lattice structure shell made from a high-performance polymeric material blend, combining flexibility and weight-saving properties with soft viscoelastic PU foam construction. Its ergonomic design helps absorb impacts while promoting airflow and breathability.
Nucleon PU foam in the central spine area provides additional impact absorption, while the convex central hard-shell design provides protection for the spinal area. Horizontal flex grooves support an adaptive fit across riding positions. The adjustable rib protector adds side protection, and shoulder blade protective padding extensions help guard the acromion bones.
A waist adjustment, slim vented kidney belt and adjustable detachable elastic shoulder straps with a snap-fit system support a customized, stable fit. The protector is compatible with Nucleon KR-C and Nucleon KR-TB protectors. Manufacturer part number: 6504718-13-S. Vendor part number: 6504718-13-S.
