Engineered by Triumph for the naked motorcycle segment, the 1997 Triumph Speed Triple T509 pairs a 885 cc (54 cu in) liquid-cooled in-line three, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 108 HP (78.8 kW) while maximum torque reaches 85 Nm (62.7 lb-ft) at 7,600 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 122 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.
On the scales, the Speed Triple T509 measures 196 kg (432 lbs) dry, translating to a power-to-weight ratio of 0.55 HP/kg (1.81 kg per horsepower). Rider ergonomics and chassis geometry center around a 800 mm (31.5 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance.
