Technical Overview
2020 Triumph Street Triple S A2 Licence Technical Analysis & Specification Breakdown
At the heart of the 2020 Triumph Street Triple S A2 Licence naked motorcycle, Triumph utilizes a 660 cc (40.3 cu in) liquid-cooled in-line three, four-stroke layout. In factory specification, peak output is rated at 46.9 HP (34.3 kW) at 11,000 rpm while maximum torque reaches 60 Nm (44.3 lb-ft) at 5,100 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 71.1 HP per liter and a 5,900 rpm working window between peak torque (5,100 rpm) and peak power (11,000 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 A2 Licence measures 168 kg (370 lbs) dry, translating to a power-to-weight ratio of 0.28 HP/kg (3.58 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 4.5 L/100 km provides an estimated theoretical range of roughly 387 km (240 miles) between fill-ups.
