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

The Piaggio 162105 rear mudguard, commonly called a mud flap or rear body protection, is the original two-tone black and grey spare part for the first series Vespa PX / PE: the P125X, P150X, and P200X generation, which predates the Arcobaleno. It is mounted on the lower part of the rear body and protects the rear 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 PXs, because it works in the most exposed part of the scooter.

✓ Strengths

• Original Piaggio spare part – OEM code 162105, not an aftermarket reproduction
• Two-tone black and grey – the standard finish of the first series, not a solid replacement color
• 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 – it mounts to the original body attachment points, no drilling or adaptation required
• The visible detail – on a conservative restoration, this is one of the details that distinguish a well-maintained Vespa from one that has been haphazardly reassembled
• Discontinued code – available while stock lasts

Vehicle compatibility

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

Recommended products

• Piaggio 5769690090 black rear mudguard – the same part for more recent Vespa PX models: if yours is not a first series, this is what you need
• Original Piaggio 272834 seat with chrome grab handle – for Vespa PX 125/150/200 Arcobaleno
• Mounting screws and washers – not included: on a vintage scooter, it is better to replace them with new ones rather than reuse rusty ones

Who it's perfect for

This is the part for those restoring a first series PX and don't want to end up with an aftermarket part that's noticeable from two meters away. The rear mudguard is one of those parts on vintage Vespas that is either completely missing – removed years ago and never replaced – or has remained there, cracked and deformed by the sun and parking bumps. Replacing it with an original one is inexpensive, takes minutes to install, and closes off the rear of the scooter just as it came from the factory, two-tone included. This applies both to conservative restorations, where every correct code matters, and to those who actually use their PX and simply want to stop getting the rear of the body dirty with mud after every rain. As this is a discontinued code, those working on it now should get it while it's still available.

Frequently Asked Questions

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

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 all black or all grey, it was likely an aftermarket replacement.

What is the difference between 162105, 219110, and 5769690090?
They are the same rear mudguard in three versions for three different PX series: 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 interchangeable at a glance: order based on your Vespa's series.

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

Does it mount without drilling?
Yes. It is the standard replacement part: it uses the existing attachment points on the rear body, without modifications. Just make sure, during installation, that it does not interfere with the wheel or the license plate holder.

Is it original Piaggio or a reproduction?
It is the original Piaggio spare part, code 162105, now discontinued. There are reproduced mudguards available that reference this code, but they are produced by third parties: this is the genuine Piaggio part.
