Piaggio 624580 Saddle Lock Kit – Liberty 50, 125, 150, and 200 (2005-2008)

The Piaggio 624580 seat lock kit is the original replacement part that restores seat opening functionality on the Liberty, from 50 to 200 cc. It is one of the most annoying faults that can happen to a scooter used every day: the seat no longer opens with the key, or — worse — it does not stay closed, and you only find out when your helmet has disappeared. On the Liberty, the lock works under rain and dust for years; the cylinder oxidizes, the spring loses tension, and the mechanism begins to act up: first you have to turn the key twice, then even that is no longer enough. Changing the assembly with the original Piaggio kit solves the problem at the root, without having to force or dismantle half the bodywork to open the compartment.

✓ Key Strengths

• Original Piaggio spare part — manufacturer code 624580, official name "SEAT LOCK KIT"
• Supplied as a kit by the official network, from the "Seat / seats – tool kit" diagram of the catalog
• Covers the entire Liberty range of those years — 50 2T and 4T, 125, 150, and 200, including the Sport versions
• Fixes both the seat that won't open and the one that won't hold: these are two sides of the same mechanism
• New mechanics, without the oxidation and play that make a used cylinder temperamental
• Safety component: a seat that doesn't lock means your helmet and documents are free to disappear

Frequently asked questions

What is the 624580 kit?
It is the original Piaggio seat lock kit, as named in the catalog. It is part of the "Seat / seats – tool kit" diagram and is the assembly that controls the opening and closing of the seat, and therefore access to the under-seat compartment, on the Piaggio Liberty.

Which Liberty models does it fit?
It fits the Liberty 50 2T and 4T, 125, 150, and 200 of the 2005-2008 series, including the Sport versions, and models from the historical catalogs Liberty 125, 125 Leader, and 150 Leader. More recent Liberty series use different codes: in case of doubt, write to us with your chassis number.

The seat opens with difficulty: do I necessarily have to change the lock?
Not immediately. Try first with a specific lock lubricant: if the defect is only oxidation, it can often be recovered. If the problem returns after a few days, the mechanism has play and it is better to replace the assembly.

Will my scooter key continue to work?
It depends on the kit configuration, which the official catalog does not detail. If it is important for you to maintain a single key for ignition and seat, write to us before ordering: we will check together using your chassis catalog.

Is it difficult to install?
It is a job within reach for anyone with minimal manual skills: you can access the lock assembly from the under-seat compartment. The main precaution is to adjust the cylinder play after installation so that the seat closes without having to force it.
