At the heart of the 2007 Hyosung RT125 enduro - offroad motorcycle, Hyosung pairs a 124.5 cc (7.6 cu in) air-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 11.7 HP (8.5 kW) at 10,000 rpm, transferring power to the rear wheel through a 5-speed gearbox. With a specific output of 94 HP per liter, the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the RT125 measures 135 kg (298 lbs) wet (curb), translating to a power-to-weight ratio of 0.09 HP/kg (11.54 kg per horsepower). Rider ergonomics and chassis geometry center around a 790 mm (31.1 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance. The 9.1-liter (2.4 US gal) fuel tank supports practical everyday commuting and weekend road stints.
