Reviews & Tips
1. Specifically engineered for use with all Alpinestars racing suits, ensuring the dimensions, fitment, and snap compatibility are correct for the full suit range without any guesswork on compatibility
2. CE Level 2 certified performance exceeding the minimum requirements — matching the certification of the Hook and Loop version but with the snap-button suit integration of a dedicated racing insert
3. Extended side wings provide rib coverage alongside the full chest protection, and customisable central zone graphics allow personalisation of the insert visible through mesh ventilation on select suits
1. Suit-specific fitment means this insert is optimised for Alpinestars racing suits — riders with jackets should use the Hook and Loop version or Divided Chest Protector for jacket compatibility
2. Inner silicone ribbing provides anti-migration properties but adds a slight texture layer against the body for riders sensitive to surface texture differences
3. At £54.99, this is the same price as the Hook and Loop jacket version — suit riders should confirm they need the suit-specific version rather than defaulting to the more universally compatible jacket insert
Racing suits have specific chest insert requirements that differ from motorcycle jackets: the chest pocket dimensions are typically smaller and more precise, the fitment system uses snap buttons rather than hook-and-loop, and the overall construction of the suit means the insert needs to be profiled specifically for the more aggressive riding position. The Alpinestars Nucleon Plasma Full Chest Protector Insert is engineered specifically for this application, designed for all Alpinestars racing suits rather than adapted from a jacket insert format.
The protection technology is shared with the Hook and Loop jacket version: a composite construction combining Nucleon PLASMA viscoelastic compound with a semi-rigid thermoplastic central zone on the outer surface. The USDA certified bio-based Plasma material provides the soft, flexible, and adaptive comfort against the chest in normal use, while the thermoplastic central zone delivers enhanced structural performance at the critical central chest impact area.
CE Level 2 certification (EN 1621-3:2018 Level 2) confirms the insert meets the highest formally specified standard for chest insert protection, with impact performance data that exceeds the minimum certification requirements. Extended side wings provide rib protection beyond the central chest zone, addressing the lateral chest and rib impact exposure that front-only chest inserts leave unprotected.
The Plasma M design applies maximum ventilation through the insert across both the Plasma compound and the semi-rigid central zone, maintaining airflow against the chest during sustained track or race use. Silicone ribbing on the inner face prevents migration within the suit’s chest pocket, and a fully adaptive construction accommodates the natural chest curvature for maximum comfort.
The customisable central zone graphics option is a racing-specific feature visible through the mesh ventilation of select Alpinestars suits, allowing personalisation of the protection insert that is unique to the suit format.
The Nucleon Plasma Full Chest Protector Insert is for circuit and track riders who use Alpinestars racing suits and want CE Level 2 chest protection using Nucleon Plasma technology. The suit-specific engineering, snap fitment, and customisable graphics make this specifically appropriate for the racing suit environment rather than general jacket use.
