1998 Enfield 550 Lightning Technical Analysis & Specification Breakdown

At the heart of the 1998 Enfield 550 Lightning custom - cruiser motorcycle, Enfield relies on a 535 cc (32.7 cu in) single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 26 HP (19 kW) at 5,500 rpm while maximum torque reaches 42 Nm (31 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 48.6 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.
