The Triumph Trident was released in 1968, giving the British industry a three-cylinder contender in the emerging superbike class. Developed alongside the BSA Rocket 3, the T150 combined a distinctive exhaust note with strong performance and responsive handling. Its upright, air-cooled overhead-valve triple was initially matched to a four-speed gearbox.
The red T160 pictured represents the later development of the design, released for 1975. Its 740cc engine has cylinders that incline forward by 15 degrees, and the engine features a 120-degree crankshaft, 9.5:1 compression and three 27mm Amal Concentric carburettors. Electric starting, a five-speed gearbox and left-foot gear change brought the specification up to date. Hydraulic disc brakes are fitted front and rear, with telescopic forks and twin Girling rear dampers.
The orange and yellow X-75 Hurricane began as a BSA Rocket 3 styling project commissioned from American designer Craig Vetter in 1969. Marketed as a Triumph for 1973, it features flowing glass-fibre bodywork and three upswept exhausts on the right. Its 67mm × 70mm bore and stroke give a capacity of approximately 740cc, with a claimed output of 58bhp. Around 1,200 were built, making the Hurricane one of the most distinctive and collectible British triples.
