The V-Force reed valve block from Italkit has a maximum cross-section on the smallest valves. This allows the diaphragms to open and close with less inherent gas force, resulting in higher efficiency and improved motor performance. Designed for the 140cc Rotax cylinder, but can also be fitted to the original 125cc engine. You can also change the reeds from the inside. So that you can also use 32 and 34 mm carburettors, we supply you with the appropriate intake manifold. If you use a 140 cc Italkit cylinder or a 154 cc Polini cylinder kit, it is best to combine a 34 mm flat slide carburettor.
