2025 Triumph Street Triple 765 R Technical Analysis & Specification Breakdown
Engineered by Triumph for the naked motorcycle segment, the 2025 Triumph Street Triple 765 R utilizes a 765 cc (46.7 cu in) liquid-cooled in-line three, four-stroke layout. In factory specification, peak output is rated at 120 HP (87.6 kW) at 11,500 rpm while maximum torque reaches 80 Nm (59 lb-ft) at 9,500 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 156.9 HP per liter and a 2,000 rpm working window between peak torque (9,500 rpm) and peak power (11,500 rpm), the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.
On the scales, the Street Triple 765 R measures 189.2 kg (417 lbs) wet (curb), translating to a power-to-weight ratio of 0.63 HP/kg (1.58 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 1,402 mm (55.2 in) wheelbase engineered for quick, flickable steering geometry. The 15-liter (4 US gal) fuel tank paired with a rated consumption of 4.45 L/100 km provides an estimated theoretical range of roughly 337 km (209 miles) between fill-ups.
