Who it's perfect for

It's the right replacement when your Vespa 150 iGet has an irregular idle, stalls at traffic lights, jerks when you open the throttle, or the engine light comes on and the diagnosis points to the throttle body. It's also the choice for those who have tried cleaning without success: when the throttle or potentiometer are worn, the only definitive solution is replacement with the original part, which the electronics recognize without adaptations.

Frequently Asked Questions

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

Is the control unit included?
According to the German retailer heavy-tuned, the 58282R is a throttle body without an integrated control unit. However, this is a single source and on this type of item, the configuration varies from model to model: before ordering, contact us for more information and we will confirm what the package contains with photos.

How do I know if the throttle body needs replacing?
Typical symptoms are an oscillating or dropping idle, the scooter stalling when releasing the throttle, jerking on re-opening, and the engine warning light illuminated. Diagnostics show errors on the throttle potentiometer. If the symptoms return after cleaning, the component is worn and needs to be replaced.

Is a procedure required after installation?
On an injection system, replacing the throttle body may require a reset of the self-learning function with the diagnostic tool, as the control unit stores the values of the previous component. Ask your authorized workshop for confirmation if this is necessary for your model.
