FXSTB Night Train

1999 Harley-Davidson FXSTB Night Train Technical Analysis & Specification Breakdown

Built around Harley-Davidson's custom - cruiser motorcycle platform, the 1999 Harley-Davidson FXSTB Night Train pairs a 1338 cc (81.6 cu in) air-cooled v2, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 56 HP (40.9 kW) at 5,000 rpm while maximum torque reaches 97 Nm (71.5 lb-ft) at 2,300 rpm, transferring power to the rear wheel through a 5-speed gearbox and belt final drive. With a specific output of 41.9 HP per liter and a 2,700 rpm working window between peak torque (2,300 rpm) and peak power (5,000 rpm), the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.

On the scales, the FXSTB Night Train measures 293 kg (646 lbs) wet (curb), translating to a power-to-weight ratio of 0.19 HP/kg (5.23 kg per horsepower). Rider ergonomics and chassis geometry center around a 640 mm (25.2 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,696 mm (66.8 in) wheelbase engineered for planted straight-line stability. The 19.7-liter (5.2 US gal) fuel tank paired with a rated consumption of 5.9 L/100 km provides an estimated theoretical range of roughly 334 km (208 miles) between fill-ups, while factory top speed is listed at 155 km/h (96 mph).
