1972 Triumph Trident T150 Valuation Report

Date: August 2025

Historical Overview

The Triumph Trident T150 was a three-cylinder 741cc British motorcycle introduced to challenge the rising tide of Japanese competition in the early 1970s. With a 5-speed gearbox and front disc brake from 1972 onward, the T150 was fast, smooth, and distinctive. Though overshadowed commercially by the Honda CB750, it remains one of Britain’s most significant performance bikes from the era.

Conclusion

The 1972 Triumph Trident remains a key part of British superbike history. Despite being overshadowed by Japanese competition in its day, the triple-cylinder engine and handsome styling make it a strong collectible today.
