BGM Pro Minarelli diaphragm block with large GRP valves.

Ideal for use with large carburettors to achieve an optimum filling level, even at high rpm. The tough GRP plate material is optimally damped and sealed by the rubberized surface. This guarantees a long life, a quiet intake noise and a very good performance.

Only BGM Pro and Polini Evolution replacement diaphragm plates fit.

A stuffer for the perfect gas flow is included in delivery.
