Unsure if it’s the right part?
Motorcycle Spare Parts only sell genuine spare parts made by each manufacturer. The Ring Nut part has been manufactured by Piaggio and is brand new and dispatched in its original packaging.
For Mana and Mana GT applications, the 840681 ring nut secures key rotating or structural components where a threaded collar is preferred over a conventional hex nut. Its profile is made for the specific mating surfaces in Piaggio diagrams, so load is spread correctly around the part it retains.
If the original ring nut has been marked by incorrect tools or over-torque, swapping it for a new unit restores proper engagement and allows accurate torque setting. That helps avoid play and wear in assemblies that are sensitive to even small amounts of movement.
