This list is taken from the official Piaggio spare parts catalog (B2B area). If you have any doubts, send us your scooter's chassis number and we will verify the correct code.

Who is it perfect for?

It is the replacement part for those who have a 50cc 2T scooter that is leaking gasoline from the carburetor, smells like fuel, or is flooding, because the needle no longer closes its seat properly and the float bowl is overflowing. It is intended for workshops that overhaul 50cc Piaggio, Vespa, Aprilia, and Gilera carburetors, and for those restoring a Liberty, Zip, Typhoon, or Vespa LX using the original part number provided by the manufacturer.

Frequently Asked Questions

Which scooters does the Piaggio CM128501 fuel shut-off needle fit?
The code CM128501 is specified in the official catalog for many 50cc 2T models: Piaggio Liberty, Typhoon, Zip, Fly, NRG, Diesis, and Free; Vespa LX, LXV, S, Primavera, Sprint, and ET2; Aprilia SR 50, Scarabeo 50, Sport City ONE, and Mojito Custom 50; Gilera Stalker, Storm, DNA, Ice, and Runner.

Where is it located exactly?
It is inside the carburetor and is listed in the official spare parts catalog in the "Carburetor" section of the Engine group, along with the float, the float pin, and the float bowl. The float pushes it against its seat to shut off the fuel supply when the bowl is full.

Is the float included?
No. This item is the fuel shut-off needle only. The float, float bowl, and float pin have their own codes in the official spare parts catalog and must be purchased separately after verifying the code required for your specific carburetor using your chassis number.

How many pieces are needed for one scooter?
Only one. The official spare parts catalog indicates a quantity of 1 per vehicle, and the displayed price refers to the single needle. If the carburetor is quite old, it is advisable to also check the float and bowl gaskets when opening it to replace the needle.

Is this an original Piaggio spare part?
Yes, it is the original Piaggio spare part with code CM128501, new and never fitted—the same as specified by the manufacturer for these carburetors—not an equivalent needle from another production line. It is sold as a single piece and is shipped from Italy with an invoice and a 2-year warranty.

How can I be sure it is the right part for my scooter?
Check your model, version, and model year in the compatibility table: the list is derived from the official spare parts catalog. If you are not sure about the version, send us your chassis number and we will verify the correct code before you place your order.
