Street Twin

2022 Triumph Street Twin Technical Analysis & Specification Breakdown

Engineered by Triumph for the classic motorcycle segment, the 2022 Triumph Street Twin utilizes a 900 cc (54.9 cu in) liquid-cooled twin, four-stroke layout. In factory specification, peak output is rated at 65 HP (47.4 kW) at 7,500 rpm while maximum torque reaches 80 Nm (59 lb-ft) at 3,800 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 72.2 HP per liter and a 3,700 rpm working window between peak torque (3,800 rpm) and peak power (7,500 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 Twin measures 215.9 kg (476 lbs) wet (curb), translating to a power-to-weight ratio of 0.3 HP/kg (3.32 kg per horsepower). Rider ergonomics and chassis geometry center around a 765 mm (30.1 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,450 mm (57.1 in) wheelbase engineered for balanced agility and highway composure. The 12.11-liter (3.2 US gal) fuel tank paired with a rated consumption of 3.87 L/100 km provides an estimated theoretical range of roughly 313 km (194 miles) between fill-ups.
