Technical Overview
2007 Hyosung XRX 125 SM Technical Analysis & Specification Breakdown
Built around Hyosung's super motard motorcycle platform, the 2007 Hyosung XRX 125 SM relies on a 125 cc (7.6 cu in) air-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 11.4 HP (8.3 kW) at 8,500 rpm while maximum torque reaches 9.9 Nm (7.3 lb-ft) at 7,500 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 91.2 HP per liter and a 1,000 rpm working window between peak torque (7,500 rpm) and peak power (8,500 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 XRX 125 SM measures 120 kg (265 lbs) dry, translating to a power-to-weight ratio of 0.1 HP/kg (10.53 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 8-liter (2.1 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 100 km/h (62 mph).
