CE Level 1 Back Protection
The Nucleon KR-CELL is CE certified to EN 1621-2:2014 Level 1, providing certified motorcycle back impact protection.
Its protective back plate uses a blend of high-performance polymer materials engineered to balance flexibility with low weight, allowing the protector to move naturally with the rider rather than creating an unnecessarily rigid feel.
Ergonomic & Flexible Construction
The protective plate is ergonomically shaped to follow the natural curvature of the back for a closer, more comfortable fit while riding.
Horizontal flex channels allow the protector to adapt as the rider changes position on the motorcycle, helping maintain coverage whether sitting upright or adopting a more forward riding position.
Ventilation & Rider Comfort
The injected grid structure is designed to combine impact absorption with substantial airflow. Highly perforated outer layers further increase ventilation, while the soft fluted bio-foam chassis provides a comfortable interface between the protector and the rider's body.
This combination keeps the KR-CELL relatively lightweight and breathable for use beneath motorcycle jackets and other compatible outer garments.
Adjustable Fit
Adjustable and removable elastic shoulder straps use a quick-fit system for straightforward positioning. A dual hook-and-loop waist closure helps hold the protector close to the body and maintain its position while riding.
