2020 Triumph Speed Triple S Technical Analysis & Specification Breakdown
Built around Triumph's naked motorcycle platform, the 2020 Triumph Speed Triple S features a 1050 cc (64.1 cu in) liquid-cooled in-line three, four-stroke configuration. In factory specification, peak output is rated at 148 HP (108 kW) at 10,500 rpm while maximum torque reaches 116.6 Nm (86 lb-ft) at 7,150 rpm. With a specific output of 141 HP per liter and a 3,350 rpm working window between peak torque (7,150 rpm) and peak power (10,500 rpm), the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.
On the scales, the Speed Triple S measures 192 kg (423 lbs) dry, translating to a power-to-weight ratio of 0.77 HP/kg (1.3 kg per horsepower). Rider ergonomics and chassis geometry center around a 825 mm (32.5 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,445 mm (56.9 in) wheelbase engineered for balanced agility and highway composure. The 15.52-liter (4.1 US gal) fuel tank paired with a rated consumption of 5.2 L/100 km provides an estimated theoretical range of roughly 298 km (185 miles) between fill-ups.
