Engineered by Cushman for the scooter motorcycle segment, the 1959 Cushman Eagle utilizes a 318 cc (19.4 cu in) air-cooled single cylinder, two-stroke layout. In factory specification, peak output is rated at 8 HP (5.8 kW) at 5,500 rpm, 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.
On the scales, the Eagle measures 122.9 kg (271 lbs) dry, translating to a power-to-weight ratio of 0.07 HP/kg (15.36 kg per horsepower). The 7.57-liter (2 US gal) fuel tank paired with a rated consumption of 3.14 L/100 km provides an estimated theoretical range of roughly 241 km (150 miles) between fill-ups, while factory top speed is listed at 84 km/h (52 mph).
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.

Weight
Compare weight carefully because it affects low-speed handling, parking and confidence.
Fuel Capacity
Fuel capacity helps estimate touring range and how often you may need to stop.
Brakes
Brake setup is worth comparing if you ride in traffic, mountains or with a passenger.
Suspension
Suspension details can matter for comfort, road feel and long-distance riding.
Transmission
Transmission and final drive affect maintenance, smoothness and everyday usability.
