1200 Sportster Custom

1998 Harley-Davidson 1200 Sportster Custom Technical Analysis & Specification Breakdown

Engineered by Harley-Davidson for the custom - cruiser motorcycle segment, the 1998 Harley-Davidson 1200 Sportster Custom relies on a 1199 cc (73.2 cu in) air-cooled v2, four-stroke powerplant. In factory specification, peak output is rated at 59 HP (43.1 kW) at 5,200 rpm while maximum torque reaches 89 Nm (65.6 lb-ft) at 3,900 rpm, transferring power to the rear wheel through a 5-speed gearbox and belt final drive. With a specific output of 49.2 HP per liter and a 1,300 rpm working window between peak torque (3,900 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 1200 Sportster Custom measures 223 kg (492 lbs) dry, translating to a power-to-weight ratio of 0.26 HP/kg (3.78 kg per horsepower). Rider ergonomics and chassis geometry center around a 688 mm (27.1 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops.
