Built around Keeway's scooter motorcycle platform, the 2011 Keeway Silverblade 125 relies on a 124.6 cc (7.6 cu in) single cylinder, two-stroke powerplant. In factory specification, peak output is rated at 11.9 HP (8.7 kW) at 8,250 rpm while maximum torque reaches 12.5 Nm (9.2 lb-ft) at 6,000 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 95.5 HP per liter and a 2,250 rpm working window between peak torque (6,000 rpm) and peak power (8,250 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 Silverblade 125 measures 155 kg (342 lbs) dry, translating to a power-to-weight ratio of 0.08 HP/kg (13.03 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,486 mm (58.5 in) wheelbase engineered for balanced agility and highway composure. The 12-liter (3.2 US gal) fuel tank paired with a rated consumption of 2.8 L/100 km provides an estimated theoretical range of roughly 429 km (267 miles) between fill-ups.

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.
Transmission
Transmission and final drive affect maintenance, smoothness and everyday usability.
