The Triumph Trident T150 emerged in 1968 as Britain's answer to the impending wave of Japanese superbikes. Developed alongside the nearly identical BSA Rocket 3, its 740cc inline-3 engine offered a unique character and impressive performance. Despite its capabilities, its launch was delayed, and it was quickly overshadowed by the Honda CB750. Still, it established the triple-cylinder layout that became a Triumph signature.
Collectors value the Trident as the original British superbike. The T150 and later T160 models offer a raw, engaging riding experience that contrasts with their more refined Japanese rivals. Race-winning "Slippery Sam" replicas are the most coveted, representing the Trident's competition pedigree. The market is diverse, with project bikes available for a few thousand dollars while pristine originals and factory racers command top prices. The 2021 revival of the Trident name on a new 660cc model has also brought renewed attention to the classics.
Buying Tips
- Check for oil leaks, particularly around the pushrod tubes and cylinder base, which are common weak points.
- Verify matching frame and engine numbers, as non-original engines significantly impact value.
- Test the electrical system thoroughly; many owners upgrade the original Lucas components with modern electronic ignition for reliability.
- On T160 models, ensure the electric starter functions correctly both cold and hot, as they are known to be weak.
Prices range from $2,100 for projects to over $37,000 for exceptional or race-proven examples.
