High-quality 0.15 mm diaphragm made of spring steel for your moped, moped and small motorcycle with Sachs 50/2 (502), 50/3 and 50/4 engine, which is operated in combination with the swiing® ingenious diaphragm insert.
A steel diaphragm is characterized by a high ductility, which means that it can bend or deform to a certain degree without breaking. This makes it particularly resistant to shocks and sudden loads, which is an advantage in engine operation with frequent load changes. In addition, a steel diaphragm is less susceptible to mechanical wear, which extends its service life. The advantage of carbon, on the other hand, is its lower weight, which leads to faster responsiveness and lower mass inertia, allowing higher efficiency and speed to be achieved.
