The fan cover is a component of the Vespa that covers the flywheel, protecting it from dust, debris, and damage. Made of durable material, the fan cover helps maintain an optimal operating temperature and contributes to engine cooling. Additionally, it enhances the vehicle's aesthetics, giving it a more refined appearance. During maintenance, it is important to check the fan cover for any signs of wear or damage and replace it if necessary, to ensure the protection and proper functioning of the engine.
