Bell RS7-K Ultra K2025 Carbon Karting Helmet

The Bell RS7-K Ultra K2025 is the premium carbon karting version of Bell's RS7 platform, purpose-built for drivers who want lightweight construction, advanced airflow, excellent visibility, and modern aerodynamic performance.

Derived from Bell's HP7 helmet design, the RS7-K Ultra uses an ultra-lightweight Premium Carbon Composite shell combined with an advanced multi-density, multi-piece energy-absorbing liner. The innovative shell and shield design are engineered to enhance aerodynamics, energy management, and driver comfort.

A powerful ventilation system uses 14 intake and extraction channels through the top and chin bar to provide excellent airflow during demanding karting sessions. The helmet also features Bell's center and side air intake system.

The RS7-K Ultra is equipped with an optical-grade injected SE07 3MM Double Screen Anti-Fog (DSAF) shield, Bell Racing's SmartLock mechanism, and a synthetic rubber eyeport gasket designed to help protect against water and dirt ingress in changing track conditions.
