Throttle Valve & Reed Valve - 4T 2V - Original Vespa / Piaggio - CM146601

This is the original gas slide with diaphragm for the Vespa and Piaggio 2V (2-valve engines). If it is worn or broken, you will no longer accelerate properly.

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