2001 Triumph Thunderbird Technical Analysis & Specification Breakdown

Engineered by Triumph for the classic motorcycle segment, the 2001 Triumph Thunderbird features a 885 cc (54 cu in) in-line three, four-stroke configuration. In factory specification, peak output is rated at 69 HP (50.4 kW) at 8,000 rpm while maximum torque reaches 82 Nm (60.5 lb-ft) at 4,800 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 78 HP per liter and a 3,200 rpm working window between peak torque (4,800 rpm) and peak power (8,000 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 Thunderbird measures 220 kg (485 lbs) dry, translating to a power-to-weight ratio of 0.31 HP/kg (3.19 kg per horsepower). Rider ergonomics and chassis geometry center around a 776 mm (30.6 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,580 mm (62.2 in) wheelbase engineered for planted straight-line stability. The 15-liter (4 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 190 km/h (118 mph).
