Positioned in Yuki's naked motorcycle lineup, the 2006 Yuki Twinsport 125 pairs a 124 cc (7.6 cu in) air-cooled twin, two-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 11.5 HP (8.4 kW) at 10,500 rpm while maximum torque reaches 8.2 Nm (6 lb-ft) at 7,000 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 92.7 HP per liter and a 3,500 rpm working window between peak torque (7,000 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 Twinsport 125 measures 152 kg (335 lbs) dry, translating to a power-to-weight ratio of 0.08 HP/kg (13.22 kg per horsepower). The 14-liter (3.7 US gal) fuel tank paired with a rated consumption of 4 L/100 km provides an estimated theoretical range of roughly 350 km (217 miles) between fill-ups.
