About KTM

Country of Origin: Austria
Founder: Hans Trunkenpolz (later joined by Ernst Kronreif)
Best Known For: Off-road/enduro supremacy, Dakar wins, Duke/RC streetbikes, and READY TO RACE ethos

Company History

KTM evolved from a postwar repair shop into a racing juggernaut by treating competition as R&D. Lightweight two-strokes made the brand a force in motocross and enduro; later four-strokes and advanced electronics cemented dominance. Dakar Rally victories showcased reliability under extreme conditions and fed the Adventure lineup—bikes that balance long-travel composure with startling pace. On the street, the Duke and RC families brought razor geometry and punchy singles/twins to license tiers worldwide, while the 1290 Super Duke and Adventure pushed the IMU-aided edge of performance. Corporate agility—acquisitions, platform sharing with Husqvarna/GASGAS—expanded reach without blurring identity. Historically, KTM changed expectations for chassis feedback and electronics integration in dirt and on road, proving that orange-painted ferocity could also be precise. The brand’s throughline is simple: build light, communicate grip, and let riders go fast safely. Few companies have turned a color and a slogan into such a reliable proxy for results.
