1991 Triumph Trident 750 Technical Analysis & Specification Breakdown

At the heart of the 1991 Triumph Trident 750 naked motorcycle, Triumph pairs a 748 cc (45.6 cu in) liquid-cooled in-line three, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 90 HP (65.7 kW) at 10,500 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 120.3 HP per liter, the engine character is reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.
