When Triumph launched its new-for-1968 Triumph Trident T150 triple, the magazine motorheads took notice: “For you performance buffs, let us state that the Triumph Trident is the fastest street machine we have tested, bar none,” Cycle Guide enthused.

Brit mag Motorcycle Mechanics boasted: “What a fantastic machine! From a standing start to 100mph and back again in approximately 600 yards, plus a top speed of 130mph through the electronic timing gear!”

Back stateside again, Cycle World opined: “The Triumph Trident is a prestige motorcycle. An awesome number of people will find that third cylinder irresistible. It will mark its owner as surely as if he were to drive a 427ci hot pink Corvette Sting Ray among the swarming minicars of Triumph’s homeland. Single and twin cylinder bikes are commonplace; even Fours are offered by more than one manufacturer. But there is only one Three.”

The year was 1968, and it looked like Triumph had hit the bull’s-eye with its 58hp Trident T150.

Years in the making
As early as 1963, Triumph engineering bosses Bert Hopwood and Doug Hele discussed the then-radical idea of a 3-cylinder road bike, but it wasn’t until the threat of a 750cc Honda loomed on the horizon that they got the go-ahead to develop the concept. Housed in a Bonneville frame, the first prototype Trident was completed in 1965, and Hopwood claimed that it was so good from the start that it could have gone into production immediately. But it wasn’t until the end of 1968 that the Triumph Trident T150 and BSA A75 Rocket 3 motorcycles were finally in U.S. dealer showrooms, while European riders had to wait until 1969.

But why BSA and Triumph versions of the triples? American importers needed something to replace the aged BSA twins and, as the BSA group owned Triumph, it was time for a little “badge engineering.” So there were two triples: one with the engine mounted vertically and the name Triumph on the tank, and the other with the cylinder block leaning slightly forward and the tank adorned with BSA badges.

The Trident was THE first SUPERBIKE of the 60s, not the CB750, as most people are told. The Triumph could SCREAM past the Honda's top speed. I had one of the last Tridents, a '75, and man it was just too fast for comfort!

I had a '74 model for years, great bike once an electronic ignition is installed. I wouldn't own an early T150, that engine needs the five-speed gearbox, and after 40 years they're still butt ugly.

I emailed your 1969 Trident review to a buddy. He and another buddy both purchased brand new Tridents in 1969 from Triumph Detroit which was owned by Bob Leppan. I had to be different and bought a 1970 XLCH from Detroit H-D. That bike was stolen and I then bought a Honda CB750 which is probably the best bike I ever owned! Love your magazine.
