1984 KTM 125 Enduro Sport Technical Analysis & Specification Breakdown

Built around KTM's cross - motocross motorcycle platform, the 1984 KTM 125 Enduro Sport relies on a 124 cc (7.6 cu in) liquid-cooled single cylinder, two-stroke powerplant. In factory specification, peak output is rated at 6.8 HP (5 kW) at 6,500 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 54.8 HP per liter, the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.

On the scales, the 125 Enduro Sport measures 109 kg (240 lbs) wet (curb), translating to a power-to-weight ratio of 0.06 HP/kg (16.03 kg per horsepower). The 9.5-liter (2.5 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 83 km/h (52 mph).
