Vespa Air Hose Sprint 50 - 4T 3V - 45 km/h Version - 1A017437

When you want to have your moped (blue license plate) reclassified as a scooter (yellow license plate), the scooter must reach the minimum required speed.

For this, the speed-limiting restrictions built into the scooter must be replaced.

One of these parts is the air hose, which allows the engine to breathe freely again.
