Motorcycle Spare Parts only sell genuine spare parts made by each manufacturer. The Ext. Valve Spring part has been manufactured by Piaggio and is brand new and dispatched in its original packaging.
The Exhaust Valve Spring, part 873005, is used to close the exhaust valve properly on models like Dorsoduro 750/900 and Shiver 750/900 (2007–2018). It maintains correct timing and prevents valve float at higher RPM.
Replacing worn springs with this part ensures solid valve control and reduces valve-related noise or power loss, especially if your engine is past 20,000 km or showing timing symptoms.
