Technical Overview
1952 Harley-Davidson K Technical Analysis & Specification Breakdown
Positioned in Harley-Davidson's allround motorcycle lineup, the 1952 Harley-Davidson K utilizes a 743 cc (45.3 cu in) air-cooled flathead 45 degree engine layout. In factory specification, peak output is rated at 30 HP (21.9 kW), transferring power to the rear wheel through a 4-speed gearbox and chain final drive. With a specific output of 40.4 HP per liter, the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.
On the scales, the K measures 181 kg (399 lbs) dry, translating to a power-to-weight ratio of 0.17 HP/kg (6.03 kg per horsepower). Rider ergonomics and chassis geometry center around a 1 mm (0 in) wheelbase engineered for quick, flickable steering geometry. The 17-liter (4.5 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 129 km/h (80 mph).
