Built around Keeway's allround motorcycle platform, the 2006 Keeway Supershadow features a 249 cc (15.2 cu in) air-cooled v2, four-stroke configuration. In factory specification, peak output is rated at 17.7 HP (12.9 kW) at 8,000 rpm while maximum torque reaches 16 Nm (11.8 lb-ft) at 6,000 rpm. With a specific output of 71.1 HP per liter and a 2,000 rpm working window between peak torque (6,000 rpm) and peak power (8,000 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the Supershadow measures 140 kg (309 lbs) dry, translating to a power-to-weight ratio of 0.13 HP/kg (7.91 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,540 mm (60.6 in) wheelbase engineered for planted straight-line stability. The 9-liter (2.4 US gal) fuel tank paired with a rated consumption of 2.4 L/100 km provides an estimated theoretical range of roughly 375 km (233 miles) between fill-ups, while factory top speed is listed at 115 km/h (71 mph).

Use this page to compare this motorcycle by its real specifications, not only by model name. Focus on the details that affect fit, comfort, handling, range and ownership.
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.
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.
