Company History
Triumph rose, fell, and rose again—reinvented as a modern manufacturer blending heritage with sharp engineering. The Bonneville family anchors the brand with air-/liquid-cooled twins that feel timeless yet include ABS, ride modes, and refined fueling. The Speed/Street Triple lines defined playful, usable performance with characterful triples; Tiger ADV models carried that feel into distance. Triumph’s attention to finishing, dealer support, and approachable ergonomics built a wide audience—from new riders to veterans returning for a bike that feels special daily. Historically, Triumph proves that heritage can power innovation when it informs proportions, sound, and feel rather than dictating technology.
