Technical Overview
2004 Enfield US Classic 500 Technical Analysis & Specification Breakdown
Built around Enfield's naked motorcycle platform, the 2004 Enfield US Classic 500 features a 499 cc (30.5 cu in) air-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 22 HP (16.1 kW) at 5,500 rpm while maximum torque reaches 35 Nm (25.8 lb-ft) at 3,000 rpm, transferring power to the rear wheel through a 4-speed gearbox and chain final drive. With a specific output of 44.1 HP per liter and a 2,500 rpm working window between peak torque (3,000 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.
Rider ergonomics and chassis geometry center around a 760 mm (29.9 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 2.52 L/100 km provides an estimated theoretical range of roughly 575 km (357 miles) between fill-ups, while factory top speed is listed at 120 km/h (75 mph).
