Who is this perfect for

It is the right replacement when your Vespa 150 iGet has an irregular idle, shuts off at traffic lights, jerks when re-opening the throttle, or turns on the engine warning light with a diagnosis pointing to the throttle body. It is also the choice for those who have tried cleaning it without success: when the throttle plate or the potentiometer is worn, the only effective intervention is replacement with the original part, which the electronics recognize without any adaptation.

Frequently Asked Questions

Which Vespas does the 58282R throttle body fit?
On the entire 4T 3-valve 125 and 150 cc family: Vespa Primavera 150 and Vespa Sprint 150 from 2013 to 2024 in all ie, iGet, ABS, NOABS, and special series versions, Vespa LX 125 and LX 150 from 2012-2013, and Piaggio Liberty 150 4T 3V ie LEM from 2013-2014.

Is the ECU included?
According to the German retailer heavy-tuned, the 58282R is the throttle body without an integrated ECU. However, this is a single source, and for this type of item, configurations can change from model to model: before ordering, contact us for more information and we will confirm the package contents with photos.

How do I know if the throttle body needs to be replaced?
Typical symptoms include an oscillating or dropping idle, the scooter shutting off when letting go of the throttle, jerking when re-opening the throttle, and the engine warning light being on. Diagnostic errors often point to the throttle potentiometer. If the symptoms return after cleaning, the component is worn and must be replaced.

Is a procedure required after installation?
On an injection system, replacing the throttle body may require a reset of the self-learning parameters with a diagnostic tool, because the ECU stores the values of the previous component. Confirm with your authorized workshop if this is required for your model.
