At the heart of the 1966 Harley-Davidson FLH Electra Glide touring motorcycle, Harley-Davidson utilizes a 1212.7 cc (74 cu in) air-cooled v2, four-stroke layout. In factory specification, peak output is rated at 60 HP (43.8 kW) at 5,200 rpm while maximum torque reaches 94.9 Nm (70 lb-ft) at 4,000 rpm, transferring power to the rear wheel through a 4-speed gearbox and chain final drive. With a specific output of 49.5 HP per liter and a 1,200 rpm working window between peak torque (4,000 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 FLH Electra Glide measures 355.2 kg (783 lbs) dry, translating to a power-to-weight ratio of 0.17 HP/kg (5.92 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,500 mm (59.1 in) wheelbase engineered for balanced agility and highway composure. The 16-liter (4.2 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 160 km/h (99 mph).
