The 1975 Triumph Trident motorcycle remained true to the brand's three-cylinder heritage. However, it struggled to compete due to its higher price compared to the Triumph Bonneville and its inability to match the speed of emerging Japanese superbikes.

The Triumph T150 Trident and BSA Rocket 3 were launched in the U.S. in the summer of 1968, aiming to counter the growing dominance of Japanese motorcycles in the lucrative American market.
Although the two companies merged in 1951 and their motorcycles shared similar specifications, the Trident and Rocket 3 had numerous distinct differences.
Each model featured unique styling, and even the engines varied slightly: the Trident's cylinders were positioned vertically, whereas the Rocket 3's cylinders leaned forward slightly.
While both motorcycles were regarded as solid performers capable of competing with the top models of their time, their appeal diminished significantly after Honda's 750 Four was introduced shortly afterward.
Both British motorcycles underwent minor updates in the following years. However, the Rocket 3 was discontinued in 1973 (along with the BSA brand), while the Trident received a comprehensive redesign.
The updated Trident, known as the T160, introduced several new features. The most noticeable change was the slanted cylinders, which reduced the bike's overall height. Additionally, the engine was upgraded with more robust internal components and an electric starter.
To better align with American preferences and regulations, the gear shift was relocated to the left side of the motorcycle. Additionally, a modern 10-inch disc brake replaced the outdated drum brake at the front.
Despite improvements, the Trident struggled to compete with the new standards set by Kawasaki's Z-1 and other high-performance superbikes.
Moreover, the Bonneville twin-cylinder model had its engine capacity increased to 750 ccs in 1973, making it harder for buyers to justify the Trident's premium price.
Consequently, Triumph's three-cylinder model was discontinued after 1976. However, the Trident name was reintroduced in 1990 for a contemporary, water-cooled, three-cylinder motorcycle produced by a revived Triumph company.
