Thunderbird 350

2014 Enfield Thunderbird 350 Technical Analysis & Specification Breakdown

Engineered by Enfield for the classic motorcycle segment, the 2014 Enfield Thunderbird 350 relies on a 346 cc (21.1 cu in) air-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 19.8 HP (14.5 kW) at 5,600 rpm while maximum torque reaches 28 Nm (20.7 lb-ft) at 4,000 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 57.2 HP per liter and a 1,600 rpm working window between peak torque (4,000 rpm) and peak power (5,600 rpm), the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.

On the scales, the Thunderbird 350 measures 192 kg (423 lbs) wet (curb), translating to a power-to-weight ratio of 0.1 HP/kg (9.7 kg per horsepower). Rider ergonomics and chassis geometry center around a 775 mm (30.5 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,350 mm (53.1 in) wheelbase engineered for quick, flickable steering geometry. The 20-liter (5.3 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 120 km/h (75 mph).
