Technical Overview
2010 Yuki 125 SM Technical Analysis & Specification Breakdown
Built around Yuki's super motard motorcycle platform, the 2010 Yuki 125 SM utilizes a 124 cc (7.6 cu in) air-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 11.3 HP (8.2 kW) at 9,000 rpm while maximum torque reaches 9.3 Nm (6.9 lb-ft) at 8,500 rpm, transferring power to the rear wheel through chain final drive. With a specific output of 91.1 HP per liter and a 500 rpm working window between peak torque (8,500 rpm) and peak power (9,000 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 SM measures 126 kg (278 lbs) wet (curb), translating to a power-to-weight ratio of 0.09 HP/kg (11.15 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,405 mm (55.3 in) wheelbase engineered for quick, flickable steering geometry. The 7.9-liter (2.1 US gal) fuel tank paired with a rated consumption of 2.4 L/100 km provides an estimated theoretical range of roughly 329 km (204 miles) between fill-ups.
