2017 Triumph Street Triple R Technical Analysis & Specification Breakdown
Positioned in Triumph's naked motorcycle lineup, the 2017 Triumph Street Triple R pairs a 765 cc (46.7 cu in) liquid-cooled in-line three, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 118 HP (86.1 kW) at 12,000 rpm while maximum torque reaches 77 Nm (56.8 lb-ft) at 9,400 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 154.2 HP per liter and a 2,600 rpm working window between peak torque (9,400 rpm) and peak power (12,000 rpm), the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.
On the scales, the Street Triple R measures 166 kg (366 lbs) dry, translating to a power-to-weight ratio of 0.71 HP/kg (1.41 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 4.7 L/100 km provides an estimated theoretical range of roughly 370 km (230 miles) between fill-ups.
