Positioned in Keeway's classic motorcycle lineup, the 2007 Keeway Speed 125 utilizes a 125 cc (7.6 cu in) air-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 10.7 HP (7.8 kW) at 8,500 rpm while maximum torque reaches 9.9 Nm (7.3 lb-ft) at 7,500 rpm. With a specific output of 85.6 HP per liter and a 1,000 rpm working window between peak torque (7,500 rpm) and peak power (8,500 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 Speed 125 measures 120 kg (265 lbs) dry, translating to a power-to-weight ratio of 0.09 HP/kg (11.21 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,300 mm (51.2 in) wheelbase engineered for quick, flickable steering geometry. The 11-liter (2.9 US gal) fuel tank paired with a rated consumption of 2 L/100 km provides an estimated theoretical range of roughly 550 km (342 miles) between fill-ups.
Within MotoLibrary's Keeway archive, this model family spans 6 indexed model years from 2006 to 2012, allowing buyers to track year-over-year changes in emissions tuning, weight and equipment.

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.
