At the heart of the 1952 Hercules 315 sport motorcycle, Hercules pairs a 247 cc (15.1 cu in) air-cooled single cylinder, two-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 11.4 HP (8.3 kW) at 4,600 rpm, transferring power to the rear wheel through a 4-speed gearbox and chain final drive. With a specific output of 46.2 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 315 measures 140 kg (309 lbs) dry, translating to a power-to-weight ratio of 0.08 HP/kg (12.28 kg per horsepower). The 13-liter (3.4 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 105 km/h (65 mph).
