Unsure if it’s the right part?
Motorcycle Spare Parts only sell genuine spare parts made by each manufacturer. The Stud Bolt part has been manufactured by Piaggio and is brand new and dispatched in its original packaging.
The 890661 stud bolt is a threaded rod used in engine and exhaust assemblies on Mana models, where consistent clamping under thermal load is required. Its material grade and thread engagement length provide stable torque retention in high-temperature zones.
Studs are often replaced when corrosion or galling affects removal. Using the OEM stud ensures proper stretch characteristics and maintains the alignment of mating components such as flanges and manifolds.
