Built around Cushman's scooter motorcycle platform, the 1958 Cushman Eagle pairs a 318 cc (19.4 cu in) single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 8 HP (5.8 kW), transferring power to the rear wheel through a 2-speed gearbox and belt final drive. With a specific output of 25.2 HP per liter, the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.
Within MotoLibrary's Cushman archive, this model family spans 16 indexed model years from 1950 to 1965, allowing buyers to track year-over-year changes in emissions tuning, weight and equipment.
