At the heart of the 1992 Harley-Davidson XLH Sportster 1200 custom - cruiser motorcycle, Harley-Davidson pairs a 1198 cc (73.1 cu in) air-cooled v2, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 49 HP (35.8 kW) at 5,200 rpm while maximum torque reaches 84 Nm (62 lb-ft) at 3,500 rpm, transferring power to the rear wheel through a 5-speed gearbox and belt final drive. With a specific output of 40.9 HP per liter and a 1,700 rpm working window between peak torque (3,500 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 XLH Sportster 1200 measures 226 kg (498 lbs) wet (curb), translating to a power-to-weight ratio of 0.22 HP/kg (4.61 kg per horsepower). The 8.5-liter (2.2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
