The carburettor diaphragm is the rubber part that controls the opening of the carburettor: this part is made for Piaggio Liberty 125-200, Vespa LX 125-150 and Aprilia Sportcity One 125 and matches the shape and function of the original.

When to replace it

Over time the diaphragm cuts or tears and the carburettor no longer works properly: the scooter struggles to start, runs badly or will not start at all. Replacing it is simple and quick, exactly as with the original diaphragm.

Features

• Like the original, same shape and function
• Simple, quick replacement
• Restores proper carburation
• The needle is not included: use the standard one

Compatibility

Piaggio Liberty 125-200, Vespa LX 125-150 and Aprilia Sportcity One 125. Check the diaphragm’s shape and diameters by comparing it with yours, and see the applications table below for the main models.

Fitting tips

Take off the carburettor cover, remove the damaged diaphragm and fit the new one without creases, reusing the standard needle. If you lack experience, have a workshop do it.
