Reed valve VForce3 - KX85

KX85 Reed blade: 0.40 mm (carbon fiber) C - C dimensions between holes: 46 mm / 55,8 mm Inside diameter of the duct: 27,6x30.1 mm The design traditionally reduces "back-flow" and with it give them better throughput through the cylinder which ultimately gives you more power and better gas response. Minarelli horizontal: crankcase has to be opened a little or use an adapter / spacer (MXS-012ET001). AM6 and Derbi: add a spacer under reed valve
