Historical Context

The Triumph Trident T150T was introduced in 1968 as one of the earliest production motorcycles to feature a three-cylinder engine. It was designed to bridge the gap between traditional British parallel twins and the more powerful multi-cylinder motorcycles that were beginning to dominate the market. The Trident was developed alongside its sibling, the BSA Rocket 3, and the two models shared many components but featured distinct styling. With its 750cc three-cylinder engine, the T150T aimed to offer smoother performance, more power, and a refined riding experience. The 1969 model represents the early years of this groundbreaking design, combining British craftsmanship with innovative engineering.
