Sting 125

1997 KTM Sting 125 Technical Analysis & Specification Breakdown

At the heart of the 1997 KTM Sting 125 super motard motorcycle, KTM relies on a 125 cc (7.6 cu in) liquid-cooled single cylinder, two-stroke powerplant. In factory specification, peak output is rated at 14 HP (10.2 kW) at 7,500 rpm while maximum torque reaches 11 Nm (8.1 lb-ft) at 6,800 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 112 HP per liter and a 700 rpm working window between peak torque (6,800 rpm) and peak power (7,500 rpm), the engine character is reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.

On the scales, the Sting 125 measures 124 kg (273 lbs) dry, translating to a power-to-weight ratio of 0.11 HP/kg (8.86 kg per horsepower). Rider ergonomics and chassis geometry center around a 820 mm (32.3 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams.
