Built around Yuki's naked motorcycle platform, the 2010 Yuki 125 CRS features a 124.6 cc (7.6 cu in) liquid-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 11.4 HP (8.3 kW) at 10,500 rpm while maximum torque reaches 9.2 Nm (6.8 lb-ft) at 6,500 rpm, transferring power to the rear wheel through chain final drive. With a specific output of 91.5 HP per liter and a 4,000 rpm working window between peak torque (6,500 rpm) and peak power (10,500 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 125 CRS measures 165 kg (364 lbs) dry, translating to a power-to-weight ratio of 0.07 HP/kg (14.47 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,480 mm (58.3 in) wheelbase engineered for balanced agility and highway composure. The 18.5-liter (4.9 US gal) fuel tank paired with a rated consumption of 2.2 L/100 km provides an estimated theoretical range of roughly 841 km (523 miles) between fill-ups.

Notes
Yuki bikes 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.
