Engineered by Yuki for the super motard motorcycle segment, the 2010 Yuki Megelli 125m relies on a 125 cc (7.6 cu in) air-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 10.5 HP (7.6 kW) at 9,500 rpm while maximum torque reaches 8.7 Nm (6.4 lb-ft) at 5,500 rpm, transferring power to the rear wheel through chain final drive. With a specific output of 84 HP per liter and a 4,000 rpm working window between peak torque (5,500 rpm) and peak power (9,500 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
Rider ergonomics and chassis geometry center around a 1,850 mm (72.8 in) wheelbase engineered for planted straight-line stability. The 6.7-liter (1.8 US gal) fuel tank paired with a rated consumption of 2.4 L/100 km provides an estimated theoretical range of roughly 279 km (173 miles) between fill-ups, while factory top speed is listed at 85 km/h (53 mph).

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.
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.
