Overview

The Polini fan is a cooling fan designed as a spare part for Polini Sport Ignition systems on Vespa Smallframe models. Manufactured from robust plastic, this fan is intended to reduce the rotating mass of the fan wheel, allowing for a more responsive engine. It includes special bushings to ensure secure mounting to the flywheel and prevent damage to the plastic.
Show original supplier description
The Polini fan (171.0644) is a plastic cooling fan specifically designed to serve as a replacement part for Polini Sport Ignition systems on Vespa Smallframe motorcycles. Constructed from durable plastic, this fan weighs 1100g, as noted in some product listings. The package includes specialized bushings that facilitate a secure bolting of the fan wheel to the flywheel while also protecting the plastic from bolt head indentation. This ensures a reliable and long-lasting fitment. This component is compatible with various Vespa models, including the 50, 125, PV, ET3, PK, XL, and XL2. It is an ideal choice for owners looking to maintain or enhance the cooling efficiency and performance of their Vespa's ignition system, particularly when using a Polini ignition. It is important to note that this fan is designed as a spare part for existing Polini ignition systems on these Vespa models. Ensure compatibility with your specific Polini ignition setup before purchasing.
