Built around Yuki's scooter motorcycle platform, the 2010 Yuki 125 Arrow pairs a 124.6 cc (7.6 cu in) air-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 8.3 HP (6.1 kW) at 7,750 rpm while maximum torque reaches 8.6 Nm (6.3 lb-ft) at 4,750 rpm, transferring power to the rear wheel through a automatic gearbox and chain final drive. With a specific output of 66.6 HP per liter and a 3,000 rpm working window between peak torque (4,750 rpm) and peak power (7,750 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 125 Arrow measures 138 kg (304 lbs) dry, translating to a power-to-weight ratio of 0.06 HP/kg (16.63 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,550 mm (61 in) wheelbase engineered for planted straight-line stability. The 11-liter (2.9 US gal) fuel tank paired with a rated consumption of 2.3 L/100 km provides an estimated theoretical range of roughly 478 km (297 miles) between fill-ups, while factory top speed is listed at 79 km/h (49 mph).

Notes
Yuki scooters are sold in The Czech Republic and The Slovak Republic.
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.
