2020 Triumph Street Triple S Technical Analysis & Specification Breakdown
Engineered by Triumph for the naked motorcycle segment, the 2020 Triumph Street Triple S utilizes a 760 cc (46.4 cu in) liquid-cooled in-line three, four-stroke layout. In factory specification, peak output is rated at 53.2 HP (38.9 kW) at 11,250 rpm while maximum torque reaches 61 Nm (45 lb-ft) at 6,000 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 70 HP per liter and a 5,250 rpm working window between peak torque (6,000 rpm) and peak power (11,250 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the Street Triple S measures 168 kg (370 lbs) dry, translating to a power-to-weight ratio of 0.32 HP/kg (3.16 kg per horsepower). Rider ergonomics and chassis geometry center around a 810 mm (31.9 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 5.11 L/100 km provides an estimated theoretical range of roughly 341 km (212 miles) between fill-ups.
