Stage6 V-Force 4 reed valve by Moto Tassinari for Derbi 50cc mopeds & Honda CR85R.
Stage6 have decided to include V-Force 4 in their catalogue. This reed valve can be fitted to Derbi EBE/EBS & D50B0/1 engines with some slight modifications the crankcases. V-Force 4 offers further improved performance to get the most out of your engine. The double valve design seen in previous versions of the V-Force valve is even more efficient and robust for high end usage.
Improvements over V-Force 3:
Curved petals for sealing.
Carbon fibre weave.
Wider reed cage.
10.5% larger petal surface
Aerodynamically optimised layout.
Rubberised block reducing wear.
You will need to mill the crankcases slightly to fit Derbi engines!
