Bell GT6 RD ULTRA-4C/EC Carbon Helmet
Pre-Order Only. ETA is Q1 of 2026.
The Bell GT6 RD ULTRA-4C/EC delivers pro-grade safety and communication in a lightweight, closed-cockpit package. Drawing design inspiration from the aggressive HP6 platform, it features a wide eyeport for integrated visibility, a premium carbon composite shell, and all-in communications and hydration solutions built in.
4C: Carbon Composite 4 Layer Construction
On Bell helmets, “4C” stands for “Carbon Composite 4 Layer Construction.” It refers to the shell technology Bell uses: a 4-layer carbon composite laminate. This blend typically combines carbon fiber with other advanced fibers (like Kevlar® or fiberglass) in multiple layers. The purpose is to deliver a shell that is lighter than fiberglass alone, but more affordable and versatile than Bell’s top-end full carbon HP series shells (like HP7 or HP77 which use pure carbon/advanced aerospace layups).
EC: Electronic Communications Integration
The "EC” in model name means the helmet incorporates an electronic comms and hydration kit integration. The closed-face GT6 RD ULTRA-4C/EC integrates the latest technology from ZeroNoise® including advanced electronics, high power speakers, and noise canceling microphone to assure outstanding performance, sound insulation, and communication efficiency.
Ultra-Light Carbon Construction Meets Pro Racing Preparedness
Built with superior carbon-glass composite materials, the helmet keeps fatigue low and track awareness high. Integrated ZeroNoise® electronics, high-power speakers, and a noise-canceling mic ensure outstanding comms and sound insulation. The face piece is also optimized for ventilation and hydration—perfect for endurance and closed-cockpit racers.
