Throttle slide valve & membrane - 4T 2V - Vespa / Piaggio original - CM146601

This is the original diaphragm throttle slide for the Vespa and Piaggio 2V (two-valve engines). If it's worn or broken, you won't be able to accelerate at all.

For optimal performance and a long service life, especially when it comes to engine parts, install original Vespa/Piaggio parts.
