    Slab-sided gas tank and "Ray-Gun" mufflers look cool today, but were just plain weird in 1968, keeping sales slower than hoped. It didn't help that Honda announced the CB750 Four the same year.

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.

I had a 74 (Black/Gold) and I considered it anything but 'Butt-Ugly' (still do!) and was certainly better looking than the chunky Honda 750 which it would eat for lunch, day in and day out. Also much nimbler than the Honda, part of which I attribute to the excellent Dunlop tires which had tread going up the sidewalls whereas the Honda rubber did not have this feature.

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.
