Engineered by Triumph for the custom - cruiser motorcycle segment, the 2011 Triumph Thunderbird Storm pairs a 1699 cc (103.7 cu in) liquid-cooled twin, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 97 HP (70.8 kW) at 5,200 rpm while maximum torque reaches 155.9 Nm (115 lb-ft) at 2,950 rpm, transferring power to the rear wheel through a 6-speed gearbox and belt final drive. With a specific output of 57.1 HP per liter and a 2,250 rpm working window between peak torque (2,950 rpm) and peak power (5,200 rpm), the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.
On the scales, the Thunderbird Storm measures 338.4 kg (746 lbs) wet (curb), translating to a power-to-weight ratio of 0.29 HP/kg (3.49 kg per horsepower). Rider ergonomics and chassis geometry center around a 699 mm (27.5 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,613 mm (63.5 in) wheelbase engineered for planted straight-line stability. The 21.95-liter (5.8 US gal) fuel tank supports practical everyday commuting and weekend road stints.
