Engineered by Sachs for the scooter motorcycle segment, the 2016 Sachs MadAss 125 relies on a 119.7 cc (7.3 cu in) air-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 8.2 HP (6 kW) at 8,400 rpm, transferring power to the rear wheel through a 4-speed gearbox and chain final drive. With a specific output of 68.5 HP per liter, the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the MadAss 125 measures 105 kg (231 lbs) wet (curb), translating to a power-to-weight ratio of 0.08 HP/kg (12.8 kg per horsepower). Rider ergonomics and chassis geometry center around a 720 mm (28.3 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,235 mm (48.6 in) wheelbase engineered for quick, flickable steering geometry. The 5-liter (1.3 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 90 km/h (56 mph).
