Easy to navigate website & reasonable postage considering delivery from the Netherlands to UK. Found what I needed for my 22 year old GSXR. Would definitely use MSP again

The Filter is a genuine spare part manufactured by Piaggio so you have peace of mind the Filter part being sold by Motorcycle Spare Parts is both original and new.
Used in secondary-air and flywheel-magneto cover oil-separation layouts, 831257 is a small filter element intended to keep the system passages clear without changing flow characteristics. It’s a simple service part, but the correct media and form factor matter because these housings don’t tolerate swelling, fraying edges, or loose fit.
MSP lists broad compatibility across Piaggio-group 125–200 4T platforms (including Atlantic, Beverly, Scarabeo, Sport City, Vespa GT/GTS/GTV, and others across 1998–2016). Verify the exact assembly callout in your diagram, as “Filter” can refer to multiple small elements on the same engine family depending on emissions spec.
