Here you can get a racing reed valve block for mopeds with D50B0, EBS and Minarelli AM6 engines.

 The advantage over the original membrane block lies in the larger cross-section and the plastic membranes.

 These are significantly more flexible than the original sheet metal ones and noticeably improve the throttle response and revving ability of the engine.

 Suitable for:
 - Derbi
 - Aprilia
 - Gilera
 - Rieju
 - Beta
 - Sherco
 - Vent
 - Motorhispania
 - Yamaha
 - Malaguti
