Founded in 1986 by Graeme Leatt, a former motocross rider and engineer, the brand began as a small operation in New Zealand focused on developing superior neck braces for off-road motorcycle racing. Recognizing the lack of effective protection against hyperextension injuries, Graeme designed the first commercial neck brace, which quickly gained traction within the motocross community for its ability to significantly reduce the risk of spinal trauma during crashes.

Over the decades, Leatt expanded its portfolio beyond neck protection to include comprehensive head and body armor systems. The brand became a staple in off-road motorsports, particularly in motocross, enduro, and trials, where their helmets and protective suits are renowned for their ventilation, impact absorption, and durability. While rooted in New Zealand's rugged terrain, Leatt established a global presence by collaborating with professional athletes and adapting its technology for various disciplines, including street motorcycle riding and mountain biking.

In the modern era, Leatt has positioned itself as a premium safety brand that bridges the gap between extreme sports performance and everyday rider protection. Their product lines now feature advanced materials like carbon fiber composites and multi-density foam liners, catering to both professional racers and recreational enthusiasts. Today, Leatt remains a dominant force in the protective gear market, celebrated for its commitment to innovation driven by real-world crash data and rider feedback.
