High-quality 0.25 mm carbon diaphragm from Polini 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.
Here are the key points that will tell you when a thin, thick or steel diaphragm is the best choice instead of a carbon diaphragm:
Torque and power development: A thinner diaphragm can help the engine to respond faster and more smoothly, as it reacts more quickly to changes in pressure. On the other hand, a thicker diaphragm can help the engine to develop higher torque at lower engine speeds, which can be particularly beneficial for low-speed engines.
