Engineered by Kawasaki for the enduro - offroad motorcycle segment, the 1977 Kawasaki KE-250 relies on a 250 cc (15.3 cu in) single cylinder, two-stroke powerplant. In factory specification, peak output is rated at 27 HP (19.7 kW) at 6,600 rpm while maximum torque reaches 25 Nm (18.4 lb-ft) at 4,600 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 108 HP per liter and a 2,000 rpm working window between peak torque (4,600 rpm) and peak power (6,600 rpm), the engine character is reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.
On the scales, the KE-250 measures 120.2 kg (265 lbs) dry, translating to a power-to-weight ratio of 0.22 HP/kg (4.45 kg per horsepower). Rider ergonomics and chassis geometry center around a 836 mm (32.9 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams. The 8.71-liter (2.3 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 128 km/h (80 mph).

Torque
Torque is useful for judging real-world pull, especially for touring, commuting and loaded riding.
Seat Height
Check the seat height against your inseam and riding posture before choosing a motorcycle.
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.
Transmission
Transmission and final drive affect maintenance, smoothness and everyday usability.
