Designed for road and sport riding, the Nucleon Plasma Full Back Protector Insert is a motorcycle back protector insert. CE Level 2 EN 1621‑2:2014 and UKCA certified, it uses Nucleon Plasma Technology—an eco‑friendly, lightweight compound with perforations and airflow channels for energy absorption and breathability. An ultra‑adaptive profile compresses and extends for low‑bulk coverage and soft‑touch comfort.
  • Ventilation system: Extensive perforations plus lateral and longitudinal airflow channels promote continuous cooling and breathability; soft-touch inner liner enhances on-skin comfort.
  • Lightweight construction: Low-mass back protector insert offered in three waist-to-shoulder dimensions for precise coverage across a wide range of body sizes.
  • Nucleon Plasma Technology: Race-developed material and design balance force dispersion, density, thickness, and pliability for confident, all-ride comfort.
  • Tailored geometry: Zoned lattice mapping allows high airflow and flexibility while maintaining coverage and stability inside the jacket pocket.
  • Adaptive flexibility: Innovative structure compresses and extends to move with the rider, delivering an ultra-adaptive, low-bulk fit.
  • According to European statutory law the CE mark is a conformity requirement for the marketing of this product. The following standards apply to this product: Back Protector: Category II EN 1621-2:2014 Level 2.
  • UKCA certified back protector performance.
  • Nucleon Plasma Technology impact-absorbing core designed for high energy attenuation and effective force dispersion.
  • Ultra-adaptive geometry compresses and extends to help maintain stable back coverage during rider movement.
  • Extensive perforations with lateral and longitudinal channels engineered to promote heat dissipation while maintaining impact protection performance.
  • Developed in three waist-to-shoulder dimensions to optimize protective coverage across a wide range of body sizes.
  • Impact performance far exceeds the requirements of the applicable CE standard.
  • Nucleon Plasma Technology impact core constructed from a bio‑based material blend with high‑performance polyurethane.
  • Engineered micro‑perforation pattern with lateral and longitudinal channel arrays formed throughout the core.
  • Skin‑side finished with a soft‑touch textile coating.

Protection

Innovative impact absorbing protection that is elastic, forgiving, and moves with the natural movement of the body

Image 47284479754575

Breathability

The innovative structural design allows the protector to be slim and to have a high level of breathability, as well as flexibility, due to the high percentage of perforation attributed to the "M" shaped design.

Comfort

The inner side of certain protectors are laminated with a smooth fabric which provides a soft and comfortable feeling. The fabric adds durability and prevents possible tearing of the viscoelastic material.

Adaptive

The compound, combined with the 3D engineered structure, provides a very flexible and adaptive platform. The "M-shaped" structural design maximizes the area of protection while at the same time provides superior adaptivity.

Impact Performance

The combination of this structure and material results in a protector that is equally protective at any given point of the structure, while at the same time, is also flexible in any direction.
