Motorcycle - Water pump impeller in DUCATI motorcycles
Check against the official notice below — it lists the full affected range.
Certain Ducati Monster S4 RS and ST3 motorcycles contain a defective water pump impeller with a shortened shaft that fails to properly engage the timing lay shaft. This defect prevents the cooling system from functioning correctly, allowing coolant temperatures to exceed safe levels even when electric fans operate normally. The resulting engine overheating can damage internal engine components such as pistons, potentially causing engine seizure and stalling that could lead to crashes.
The recall affects specific frame serial number ranges for both USA and Europe versions of the Monster S4 R, Monster S4 RS, and ST3 models. The importer has undertaken voluntary corrective actions to address the issue. The source document does not specify what remedy or actions affected consumers should take.

This product poses a risk of injuries because the water pump impeller does not turn as a new impeller, with a wrong shaft – which is shorter than the nominal one, and does not engage on the timing lay shaft – was installed. Due to this reason, the cooling system does not work properly (Coolant temperature easily exceeds the max. allowed value of > 120° C, even if electric fans correctly switch on), with a consequent damage of some engine parts (piston seizure, for example). That may allow the engine to stall, causing a crash.
