Built around Sachs's enduro - offroad motorcycle platform, the 2001 Sachs ZZ 125 features a 124.9 cc (7.6 cu in) single cylinder, two-stroke configuration. In factory specification, peak output is rated at 14.8 HP (10.8 kW) at 8,000 rpm while maximum torque reaches 12.9 Nm (9.5 lb-ft) at 7,750 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 118.5 HP per liter and a 250 rpm working window between peak torque (7,750 rpm) and peak power (8,000 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 ZZ 125 measures 118 kg (260 lbs) dry, translating to a power-to-weight ratio of 0.13 HP/kg (7.97 kg per horsepower). Rider ergonomics and chassis geometry center around a 825 mm (32.5 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,420 mm (55.9 in) wheelbase engineered for balanced agility and highway composure. The 14.6-liter (3.9 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 106 km/h (66 mph).
