SM 125

2001 MZ SM 125 Technical Analysis & Specification Breakdown

Built around MZ's super motard motorcycle platform, the 2001 MZ SM 125 features a 124 cc (7.6 cu in) single cylinder, four-stroke configuration. In factory specification, peak output is rated at 15 HP (10.9 kW) at 9,000 rpm while maximum torque reaches 11.7 Nm (8.6 lb-ft) at 8,500 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 121 HP per liter and a 500 rpm working window between peak torque (8,500 rpm) and peak power (9,000 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 SM 125 measures 133 kg (293 lbs) wet (curb), translating to a power-to-weight ratio of 0.11 HP/kg (8.87 kg per horsepower). Rider ergonomics and chassis geometry center around a 830 mm (32.7 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,440 mm (56.7 in) wheelbase engineered for balanced agility and highway composure. The 13.5-liter (3.6 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 110 km/h (68 mph).
