Built around Enfield's custom - cruiser motorcycle platform, the 2005 Enfield Thunderbird A350E features a 346 cc (21.1 cu in) air-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 18 HP (13.1 kW) at 5,500 rpm while maximum torque reaches 27.1 Nm (20 lb-ft) at 3,500 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 52 HP per liter and a 2,000 rpm working window between peak torque (3,500 rpm) and peak power (5,500 rpm), the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.
On the scales, the Thunderbird A350E measures 180 kg (397 lbs) wet (curb), translating to a power-to-weight ratio of 0.1 HP/kg (10 kg per horsepower). Rider ergonomics and chassis geometry center around a 740 mm (29.1 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,370 mm (53.9 in) wheelbase engineered for quick, flickable steering geometry. The 14.5-liter (3.8 US gal) fuel tank paired with a rated consumption of 2.5 L/100 km provides an estimated theoretical range of roughly 580 km (360 miles) between fill-ups, while factory top speed is listed at 120 km/h (75 mph).

Power
Compare engine output with similar motorcycles if acceleration, highway use or two-up riding matters.
Torque
Torque is useful for judging real-world pull, especially for touring, commuting and loaded riding.
Seat Height
Check the seat height against your inseam and riding posture before choosing a motorcycle.
Weight
Compare weight carefully because it affects low-speed handling, parking and confidence.
Fuel Capacity
Fuel capacity helps estimate touring range and how often you may need to stop.
Brakes
Brake setup is worth comparing if you ride in traffic, mountains or with a passenger.
Suspension
Suspension details can matter for comfort, road feel and long-distance riding.
Transmission
Transmission and final drive affect maintenance, smoothness and everyday usability.
