Piaggio 162105 Rear Mud Flap Protector – Vespa PX / PE 125 150 200 1st Series

The Piaggio 162105 rear protector, commonly known as a mudflap or rear body guard, is the original two-tone black and grey spare part for the Vespa PX / PE first series: the P125X, P150X, and P200X generation, which preceded the Arcobaleno. It mounts to the lower part of the rear body and protects the back of the frame and the license plate from water and dirt thrown up by the wheel. It is one of the parts most often missing or damaged on vintage PX models, as it works in the most exposed area of the bike.

✓ Strengths

• Original Piaggio spare part – OEM code 162105, not a third-party reproduction
• Two-tone black and grey – the standard finish for the first series, not a solid-color replacement
• Specific to the first series – this is the part for the P125X / P150X / P200X, not for the Arcobaleno or more recent PX models
• Standard shape and holes – mounts to the original body fixing points without drilling or modifications
• A visible detail – in a conservative restoration, this is one of the details that distinguish a well-maintained Vespa from one that has just been put back together
• Discontinued code – available only while stock lasts

Technical features

Vehicle compatibility

The determining factor is not just the year but the series: this code is for the PX/PE first series. If your Vespa is an Arcobaleno or a more recent PX, a different code is required (see the box above). When in doubt, send us your chassis number.

Perfect for who

It is the part for those restoring a first-series PX who do not want to end up with an adaptable part that stands out from two meters away. The rear protector is one of those parts that on vintage Vespas is either missing entirely – removed years ago and never replaced – or has been left there, cracked and deformed by the sun and bumps in the parking lot. Replacing it with an original costs little, installs in a few minutes, and finishes the tail of the bike exactly as it left the factory, two-tone included. It is valid both for conservative restoration, where every correct code counts, and for those who actually use their PX and simply want to stop finding the back of the body covered in mud after every rain. Since this code is discontinued, those working on one now should buy it while it is available.

Frequently asked questions

How do I know if my Vespa is a "first series"?
The PX/PE first series is the P125X, P150X, and P200X generation, produced between 1977 and 1982, the one that precedes the Arcobaleno. If you find one of those codes on your registration document or chassis, this is the right part. If you have an Arcobaleno PX or a more recent PX, you need a different code: write us your chassis number and we will confirm it for you.

What color is it?
It is two-tone, black and grey: the original finish of the first series. It is not a solid color, so if the one you removed was entirely black or entirely grey, it is likely it was already a non-original replacement.

What is the difference between 162105, 219110, and 5769690090?
They are the same rear protector in three versions for three different series of PX: 162105 for the first series (two-tone black and grey), 219110 for the Arcobaleno (dark grey), 5769690090 for more recent PX models (black). They are not visually interchangeable: order based on your Vespa's series.

Are the screws included?
No. The package contains only the rear protector. Screws, washers, and mounting brackets must be salvaged from the old one or purchased separately – and on a forty-year-old Vespa, the latter is very often the better option.

Does it mount without drilling?
Yes. It is the standard replacement part: it uses the mounting points already provided on the rear body, without any adjustments. Just be careful during installation that it does not interfere with the wheel or the license plate holder.

Is it an original Piaggio part or a reproduction?
It is the original Piaggio spare part, code 162105, now discontinued. There are reproduced mudflaps out there that cite this code as a reference but are produced by third parties: this is the genuine Piaggio part.
