MZ currently manufactures a line SM of 125cc 4-stroke motorcycles using a new and powerful engine designed in house. The MZ 125SM produces 15 hp (11 kW) and almost 14 Nm of torque. It is a liquid-cooled pressure-lubricated dual overhead cam design with 4-valves, high voltage electronic ignition and an 11000rpm ignition cut-off. This is officially the most powerful 125cc 4-stroke engine mass-manufactured and has also proved highly reliable. This engine is used in 4 models of motorcycle, all of which share a common frame. The frame is a tube steel backbone with the engine as a stressed bottom member.



Changes in the suspension, gearing, and equipment make the four models relatively distinct, despite the shared platform. All bikes MZ 125 SM feature a 6-speed transmission and dual disc brakes. More specs and user manual of MZ 125 you can see in next overview.
