MOTOFORCE INLET MANIFOLD MF DERESTRICTED PIAGGIO D=21MM MF15_14000

Intake Manifold derestricted 21mm Piaggio / Gilera / Derbi / Vespa. Many stock scooter engines are restricted via an intake manifold. Replacing the stock manifold with this open, unrestricted version will boost performance. This becomes particularly important when switching to a larger carburetor. This intake manifold is suitable for 17.5mm to 21mm carburetors.
