POLINI Key - Manufacturer Ref. 230.0407
Small but essential, this POLINI key is designed for the crankshafts of vintage and urban 50cc scooters. Designed to secure and index the components mounted on the shaft (sprocket, flywheel, pulley), it ensures safe positioning during assembly and prevents any unwanted axial play. A simple replacement part, suitable for routine maintenance and refurbishment operations.
Known compatibilities: PIAGGIO BOXER, BRAVO, CBA, CIAO, ECO, GRILLO, SI. Among the most affected models are the PIAGGIO CIAO 50 (2006), the PIAGGIO GRILLO (1995), and the PIAGGIO SI (1986).
Before installation, check the condition of the bore and the groove on the shaft: a damaged key must be replaced to ensure proper centering. For a clean and safe installation, use the appropriate tools or entrust the operation to your usual mechanic.
