Reed valve Derbi euro 2-3-4 / Minarelli AM6 / Variant Metrakit V4X Vforce

Reed valve V4X Vforce from the manufacturer Metrakit for Derbi euro 2-3-4 / Minarelli AM6 / Derbi Variant.

The Metrakit V4X reed valve is the direct evolution of the legendary VFORCE3, designed for set-ups that require extra aggressiveness. Once installed, you will notice that the engine revs higher and the RPMs increase more freely, especially in the mid and high range.

Thanks to the new design of the cage and petals, the mixture flow enters the crankcase more directly and quickly, eliminating turbulence.

It can also be installed in the Metrakit Pro Race and Hiper PRO crankcase.
