Engineered by Puch for the scooter motorcycle segment, the 1970 Puch 250 SGS pairs a 248 cc (15.1 cu in) air-cooled single cylinder, two-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 14.2 HP (10.4 kW) at 5,800 rpm, transferring power to the rear wheel through a 4-speed gearbox and chain final drive. With a specific output of 57.3 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 250 SGS measures 164 kg (362 lbs) wet (curb), translating to a power-to-weight ratio of 0.09 HP/kg (11.55 kg per horsepower). The 13-liter (3.4 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 115 km/h (71 mph).
