Reed valve -BGM PRO Evolution 1- Piaggio 50-180cc speciale

The bgm PRO diaphragm block comes with a powerful two-valve diaphragm. The GRP plates are state of the art for optimal response and high performance. The GRP plates also have an extremely long service life, reducing maintenance to a minimum. This means that the plates not only seal better, but the impact of the plates on the block is also better damped. This results in a much quieter intake noise and wear and tear of the plates is significantly reduced.
The bgm PRO reed block is perfectly suited for carburettors with a passage of 19 mm or more and ensures good cylinder filling thanks to the large surface area. Two buffers for the perfect gas flow are included in delivery.
