reed valve assy Racing for AM6, Derbi, Generic, KSR-Moto, Keeway, Simson w/ reed block

Racing diaphragm block. The advantage here is the larger cross-section - compared to the standard diaphragm block - and the use of plastic diaphragms. The plastic diaphragms are lighter, more flexible and therefore faster than those made of sheet metal. This noticeably improves throttle response and revving. Steel diaphragms also cause catastrophic engine damage, while a broken plastic diaphragm is usually simply ground through without permanent damage and disposed of via the exhaust. Because of the slotted hole mounting suitable for Derbi D50B0, EBE, EBS, Minarelli AM and Simson diaphragm conversions._{AI-translation}
