2009 Triumph Street Triple Technical Analysis & Specification Breakdown
Built around Triumph's naked motorcycle platform, the 2009 Triumph Street Triple pairs a 675 cc (41.2 cu in) liquid-cooled in-line three, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 105.9 HP (77.3 kW) at 11,700 rpm while maximum torque reaches 69 Nm (50.9 lb-ft) at 9,100 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 156.9 HP per liter and a 2,600 rpm working window between peak torque (9,100 rpm) and peak power (11,700 rpm), the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.
On the scales, the Street Triple measures 167 kg (368 lbs) dry, translating to a power-to-weight ratio of 0.63 HP/kg (1.58 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, combined with a 1,395 mm (54.9 in) wheelbase engineered for quick, flickable steering geometry. The 17.4-liter (4.6 US gal) fuel tank supports practical everyday commuting and weekend road stints.
