The Trident model was introduced by Triumph Motorcycles in 1968. The first version was known as the T150 and featured a 741cc inline three engine that became a benchmark of performance and stability for its time. The Trident returned with the Hinckley era in 1991, offering 750cc and 900cc inline three engines versions. Finally in 2021, the Trident 660 was introduced with a 660cc inline three engine with electronic fuel injection. Notable for its distinctive triple cylinder design and its role in keeping alive the tradition of British high performance motorcycles, the Trident remains an iconic and versatile model within Triumph's history.
