The Piaggio 102585 is the oil reservoir cap, an original Piaggio spare part for Vespa PX 125, 150, and 200. ❗ This is not the fuel cap: it is the cap for the automatic oil mixer reservoir, the 2-stroke system that the PX doses itself. It is a small part that is easily lost during refills, and when it is missing or does not close properly, water and dirt can enter the oil – with the risk of damaging the oil pump.
✓ Key features
- Original Piaggio spare part – code 102585: exact thread and fit, closes as it should
- Keeps out water and dirt – a missing or cracked cap is the most direct way to contaminate the oil mixer fluid
- Covers the entire life of the PX – from historical catalogs to the 2017 E3 series, all engine displacements
- Costs only a few euros – the classic part that is worth keeping as a spare if you ride a PX
- In stock, immediate shipping

⚠️ Before ordering:
• This is the OIL cap, not the fuel cap. The fuel tank cap has a completely different code: if you are looking for that, please ask us.
• Applicable to PX models with an automatic mixer: manual pre-mix versions do not have this separate reservoir.
• If your old cap did not seal well, check the condition of the filler neck and the seal: a damaged thread cannot be compensated for with a new cap.
• There are many third-party equivalents available for a few euros that cite "R.O. 102585": they are not the same part. This is the original Piaggio part.

Who it is perfect for
It is the ideal spare part for anyone who owns a Vespa PX and has noticed that the oil cap is missing, cracked, or no longer screws on properly – typically after a rushed refill or after the vehicle has been sitting for a long time and the plastic has become brittle. It is also the perfect item to include in your cart during a restoration: on thirty-year-old PX models, the original cap is almost always missing, and it is one of those details that gets noticed.
