Reed valve -MALOSSI MHR- Vespa Largeframe, Smallframe, Minarelli AM6 - carbon fibre

The MHR Racing Diaphragm Blocks offer you a larger inlet area and an optimized flow pattern. This means there is no throttle in the inlet and the cylinder charge increases. This also increases the performance. As you can see: Developed for the racing engines of the Malossi Werksracer and successfully tested on the race track.
For the perfect flow a stuffer is included in the delivery. The diaphragm provides performance and reliability. Thanks to the very high quality selected materials: The housing is made of a FKM-coated aluminium- silicon alloy. Thanks to the vulcanized surface an optimal sealing of the platelets is guaranteed. This means that even with really large carburettors there is no pressure reduction in the crankcase.
