Engineered by Hyosung for the super motard motorcycle segment, the 2008 Hyosung XRX 125 Supermoto features a 124.5 cc (7.6 cu in) single cylinder, four-stroke configuration. In factory specification, peak output is rated at 10.1 HP (7.3 kW) at 10,000 rpm while maximum torque reaches 10.9 Nm (8 lb-ft) at 8,000 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 81.1 HP per liter and a 2,000 rpm working window between peak torque (8,000 rpm) and peak power (10,000 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 XRX 125 Supermoto measures 123 kg (271 lbs) dry, translating to a power-to-weight ratio of 0.08 HP/kg (12.18 kg per horsepower). Rider ergonomics and chassis geometry center around a 850 mm (33.5 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams. The 7.1-liter (1.9 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 106 km/h (66 mph).
