Street Triple

2012 Triumph Street Triple Technical Analysis & Specification Breakdown

Positioned in Triumph's naked motorcycle lineup, the 2012 Triumph Street Triple utilizes a 675 cc (41.2 cu in) liquid-cooled in-line three, four-stroke layout. In factory specification, peak output is rated at 106 HP (77.4 kW) at 11,700 rpm while maximum torque reaches 68 Nm (50.2 lb-ft) at 9,200 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 157 HP per liter and a 2,500 rpm working window between peak torque (9,200 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 189 kg (417 lbs) wet (curb), translating to a power-to-weight ratio of 0.56 HP/kg (1.78 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 1,410 mm (55.5 in) wheelbase engineered for quick, flickable steering geometry. The 17.4-liter (4.6 US gal) fuel tank paired with a rated consumption of 7.13 L/100 km provides an estimated theoretical range of roughly 244 km (152 miles) between fill-ups.
