HJC i11 Acid Skull Helmet

The HJC i11 Helmet delivers a race-inspired fit paired with the aerodynamic shaping and ventilation that sport riders rely on. Its streamlined shell is engineered to reduce lift and drag at speed, while the lightweight construction and efficient airflow system keep you comfortable whether you’re pushing through long highway stretches or carving through quick weekend sprints. With every twist of the throttle, you get dependable protection supported by features like a photochromic-ready visor system and emergency quick-release cheek pads. Sport-focused, tech-ready, and built for all-out riding—the i11 is made to perform when the pace picks up.

The HJC i11 is engineered with an Advanced Polycarbonate Compound shell that blends high-grade polycarbonate, high-impact ABS, and optimized reinforcement to deliver exceptional strength without excess weight. This construction provides reliable impact resistance and a solid, protective feel on the road while keeping the helmet light for all-day comfort. Certified to SNELL M2025D and DOT standards, the i11 meets some of the most trusted safety benchmarks in motorcycling, giving riders confidence in every mile.

The HJC i11 features the Pinlock-ready HJ-38 visor, designed to deliver clear, reliable visibility in all conditions. It provides 99% UV protection, includes an anti-scratch coating for long-lasting clarity, and uses a distortion-free optical profile so your view stays sharp edge to edge. An initial “cracked-open” position adds a burst of airflow when you need it, enhancing comfort and refreshment during rides in warmer conditions or stop-and-go traffic.

The Advanced Channeling Ventilation System (ACS) is engineered with the same cutting-edge expertise HJC applies to its MotoGP race helmets. This state-of-the-art design delivers full front-to-back airflow, directing air through the helmet to flush out heat and humidity for continuous cooling. Strategically placed intake and exhaust vents maximize circulation and maintain a balanced interior temperature, setting a new standard for aerodynamics and breathability in modern helmet design.
