Engineered by Honda for the scooter motorcycle segment, the 2002 Honda Sky relies on a 49 cc (3 cu in) single cylinder, two-stroke powerplant. In factory specification, peak output is rated at 1.9 HP (1.4 kW) at 6,000 rpm while maximum torque reaches 2.8 Nm (2.1 lb-ft) at 3,500 rpm, transferring power to the rear wheel through a automatic gearbox. Internal engine geometry specifies a bore and stroke of 39.0 x 41.4 mm (1.5 x 1.6 inches) with a 7.0:1 compression ratio.
On the scales, the Sky measures 71 kg (157 lbs) dry. Rider ergonomics and chassis geometry center around a 775 mm (30.5 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,230 mm (48.4 in) wheelbase engineered for quick, flickable steering geometry. The 4.5-liter (1.2 US gal) fuel tank supports practical everyday commuting and weekend road stints.

Power
Compare engine output with similar motorcycles if acceleration, highway use or two-up riding matters.
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.
