HJC was founded in 1971 in South Korea by Wan Ki Hong, initially focusing exclusively on the development and production of motorcycle helmets. The company remains family-owned to this day, with several of Hong's relatives holding key positions. Over the years, HJC expanded gradually and recently added bicycle helmets to its portfolio, especially in the area of performance and racing models. The expertise gained from both worlds has been integrated into development, ventilation concepts, and aerodynamics.
Concentrating on a single product segment allowed for deep specialization, leading to early international success. HJC expanded into the USA in 1986, and by 1992, it had risen to become the market leader with the best-selling helmets, maintaining this position to the present day. In 2001, HJC Europe was established near Strasbourg, currently serving over 40 European markets. Additional branches in Germany and Italy provide further regional proximity.
