Alpinestars Nucleon Kr-Y Black Red 13

The Alpinestars Nucleon KR-Y is fully designed and developed for young riders who require high-level back protection combined with comfort and freedom of movement. Its lightweight and ergonomic design ensures an optimal fit for smaller and youth body profiles.

The ergonomically shaped protective plate closely follows the natural curvature of the spine, keeping the protector securely positioned while riding. This results in a stable and comfortable fit across a wide range of riding conditions.

The Nucleon KR-Y is constructed from a soft visco-elastic PU foam compound that effectively absorbs impact energy while remaining flexible. This allows the protector to move naturally with the rider, which is essential for younger users.

An integrated airflow channeling system enhances ventilation, helping to regulate temperature and improve comfort during active riding sessions.

Adjustable and removable elastic shoulder straps make it easy to tailor the fit, while the integrated kidney belt provides additional support and keeps the protector firmly in place.

With CE Level 2 certification, the Alpinestars Nucleon KR-Y delivers reliable, high-performance back protection for young riders who prioritize safety and comfort.
