Unsure if it’s the right part?
Motorcycle Spare Parts only sell genuine spare parts made by each manufacturer. The U.Scheibe part has been manufactured by Piaggio and is brand new and dispatched in its original packaging.
On the RX/SX/ETX 125 platform family, the flat washer RB000590 is specified as a load-spreading spacer in the gearshift/engine lever assemblies (notably 2014–2018 ETX 150 and 2018 RX 125/SX 125 E4 variants). It’s a plain steel washer intended to preserve stack height and protect joint faces under clamp load where small clearances matter.
In practice, this washer is doing two jobs: maintaining alignment in a rotating or pivoting joint and keeping fastener preload stable by preventing localized deformation of the mating surface. Reuse is fine if it’s still flat and free of galling; any dishing or fretting marks are a sign to replace to keep lever travel and indexing consistent.
