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 models. It's one of the most annoying breakdowns that can happen to a daily-used scooter: the seat no longer opens with the key, or—even worse—doesn't stay closed, a fact only discovered when your helmet has disappeared. On the Liberty, the lock works under rain and dust for years, the barrel oxidizes, the spring loses tension, and the mechanism starts acting up: first, you need to turn the key twice, then even that's not enough. Replacing the assembly with the original Piaggio kit solves the problem at its root, without having to force or dismantle half the bodywork to open the compartment.

✓ Strengths

• Original Piaggio spare part — factory code 624580, official name "KIT SERRATURA SELLA" (SEAT LOCK KIT)
• Supplied as a kit from the official network, from the "Saddle / seats – tool bag" table in the catalog
• Covers the entire Liberty range from those years — 50 2T and 4T, 125, 150, and 200, including Sport versions
• Resolves both seats that won't open and those that won't stay closed: these are two sides of the same mechanism
• New mechanics, without the oxidation and play that make the old barrel capricious
• Safety component: a seat that doesn't close means your helmet and documents are free to disappear

Recommended products

If the seat lock has failed due to age, it's very likely that the rest of the locking system is just as old: in our catalog you'll find the original Piaggio ignition switch and handlebar buttons. And if the scooter has been idle for a while, it's also a good time for a new air filter, spark plug, and drive belt.

Perfect for

• Those who can no longer open the seat with the key and don't want to force it
• Those whose seat won't stay closed: a safety issue, not just an inconvenience
• Those who bought a used Liberty with a faulty or already forced mechanism
• Workshops that repair older scooters and want to finish the job with original spare parts

Frequently Asked Questions

What is the 624580 kit?
It is the original Piaggio seat lock kit, also referred to as such in the catalog. It is part of the "Saddle / seats – tool bag" table and is the assembly that controls the opening and closing of the seat, and thus access to the under-seat compartment, on the Piaggio Liberty.

Which Liberty models does it fit?
On Liberty 50 2T and 4T, 125, 150, and 200 models from the 2005-2008 series, including Sport versions, and on models from the historical catalogs Liberty 125, 125 Leader, and 150 Leader. More recent Liberty series use different codes: if in doubt, write us your frame number.

The seat is difficult to open: do I have to replace the lock?
Not immediately. First, try a specific lock lubricant: if the defect is just oxidation, it can often be recovered. If the problem reappears after a few days, the mechanism has play and it's advisable to replace the assembly.

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

Is it difficult to install?
It's a job within reach for anyone with basic manual skills: the lock assembly is accessed from the under-seat compartment. The main precaution is to adjust the play of the barrel after assembly, so that the seat closes without needing to be forced.
