1972 Triumph Trident T150
1972 TRIUMPH TRIDENT BACKGROUND
The Trident benefitted majorly from the 1971-and-later redux of the Oil-in-Frame 650 twins. While the Trident didn’t get the oil-bearing frame, it got just about everything else. Most notably, these included the new front forks sans rubber ‘gators’, the new headlight, turn signals and gauge package, the megaphone mufflers, and those great-looking conical hubs. Overall, it made for a very handsome package. Not much changed mechanically, other than typical yearly refinements. The 1972 Triumph Trident T150 was turning in to a fine machine. Unfortunately, events would soon catch up with Triumph and the whole British motorcycle industry, or at least what was left of it. But that’s another story, and one you can read by ordering the book Save the Triumph Bonneville: The Inside Story of the Meriden Workers’ Co-op
. It’s written by John Rosamond, who started out as a welder on the Triumph assembly line and ended up running the whole show. It’s an important story to all British bike nuts, real history, and a great read.
