Stage6 V-Force 3i reed valve by Moto Tassinari for Derbi 50cc mopeds & Honda CR85R.

Working closely together with the US manufacturer Moto Tassinari, who is famous for high performing reed valves in the field of motocross engines, this V-Force3 has been developed.

This construction of the double V-reeds is patented and thanks to its huge inlet diameter and an optimized airflow, it provides much better filling of the crankcase. To ensure maximum power output, you should fit the 30mm Venturi insert that is included in the package. An evolution for 50cc two-stroke automatic engines !

Slight modification to the engine casing is required to fit this reed valve.

Suitable for carburettors up to 30mm.
