Engineered by Harley-Davidson for the custom - cruiser motorcycle segment, the 1982 Harley-Davidson FXB 1340 Sturgis features a 1337 cc (81.6 cu in) air-cooled v2, four-stroke configuration. In factory specification, peak output is rated at 67 HP (48.9 kW) at 5,800 rpm while maximum torque reaches 69 Nm (50.9 lb-ft) at 3,000 rpm, transferring power to the rear wheel through a 4-speed gearbox and belt final drive. With a specific output of 50.1 HP per liter and a 2,800 rpm working window between peak torque (3,000 rpm) and peak power (5,800 rpm), the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.
On the scales, the FXB 1340 Sturgis measures 278 kg (613 lbs) wet (curb), translating to a power-to-weight ratio of 0.24 HP/kg (4.15 kg per horsepower). Rider ergonomics and chassis geometry center around a 740 mm (29.1 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops. The 15.5-liter (4.1 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 170 km/h (106 mph).
