Piaggio 641347 Roll-Lock Button Small Model – MP3 125-250-300-400-500 and Gilera Fuoco 500

The roll lock and unlock button is the control that riders of a Piaggio MP3 or a Gilera Fuoco 500 use to stiffen the front two-wheel assembly and keep the vehicle upright when stopped, without putting their feet on the ground. The code 641347 is the original Piaggio Group replacement part in the small model: black technopolymer body, central rocker lever, and plate with the two pictograms — locked suspension and free suspension. On the back, it features an integrated 4-way connector, allowing it to be directly plugged into the standard wiring.

Technical specifications

Vehicle compatibility

Who is it perfect for?

For those who have an MP3 or Fuoco with a few years on it and have noticed that the roll lock button is no longer responding as it should: a loose lever, intermittent command, or a plate damaged by sun and rain. This part is exposed on the handlebar block, so it ages faster than the rest of the vehicle. It's also good for those who keep a spare part: it's inexpensive, takes up no space, and prevents you from leaving your three-wheeler idle while waiting for an order.

Frequently Asked Questions

Is it suitable for my MP3?
It is suitable for the entire MP3 range from 125 to 500 — ie, LT, MIC, Sport, Tourer, and Hybrid versions — and for the Gilera Fuoco 500. Exact versions, years, and markets are in the table above, taken from the official Piaggio spare parts catalog (B2B).

What's the difference between the small and large models?
The plate size and the housing on the block change: the small model, which is this one, will not fit where the vehicle uses the large one and vice versa. The safest way is to compare the photos with the button you have on board, or send us the VIN.

Do I need to cut or splice wires?
No. The 4-way connector is already integrated into the button body: you just unplug the wiring from the old control and plug it into this one.

Is it an original spare part or an equivalent?
It is the original Piaggio Group spare part, code 641347. It replaces previous codes 623785 and 641053.

The roll lock no longer holds: is changing the button enough?
Not always. If the button clicks and the dashboard signals the command, the problem is usually further downstream — control unit, solenoid valve, or suspension assembly oil. The button should be changed when it itself is not responding: broken or loose lever, intermittent contact, water infiltration.

How long does it take to install?
It's a quick job: you remove the half-shell of the control block, detach the old button from the clips, swap the connector, and close it up. No special tools are needed.
