Modern Vespa

Hello everyone. I got 2023 vespa primavera s150. There is clicking sound from rear wheel. There is a video from other forum. Its the same sound i got at my vespa. They say its about wheel rim but some people say they changed the rim and sound come back again. Any idea about this and solution about it? Thank you.

Welcome to MV and congratulation on your first post.

There are already several topics about this here and in the German forum. Please search for them here, I have also linked to the German posts.

The solution is to replace the rim.

Perhaps you have the opportunity to swap it for another rim / another rear wheel as a test. Also try your rim on another vehicle. The fault will move with it...

thank you for reply. Yeah replacing rim works in some but then sound get back again.

for example: https://vespaforum.de/viewtopic.php?p=884298#p884298

and in Turkey someone changed rims 3 times and sound come back again. Could it be about bearings? I really dont understand how rims make this sound?

In both German topics on this subject, there is no other user apart from you who has given feedback that the error occurs again after rim replacement.

You are "rocknkaya", correct? (at least you both come from Turkey and both have a Sprint S 150)

yes. this is from a site form Turkey:

3rd Broken Vespa Primavera Rear Rim

On 02.11.2023, I bought a 2023 model Vespa Primavera 150 CC and 0 km engine from your official sales point Asal Motor.

28 days after purchasing, I was stranded on the road because the fuel float broke when the engine had only been used for 598 km. I reported the issue to my authorized service and the float was replaced under warranty. (01.12.2023)

1 month after this incident, when the engine was showing 1,277 km, I applied to the service in line with the sounds coming from the rear rim. The rim was replaced with the support of service representative Y**** E** and your center manager B*****. (16.01.2024)

When my engine was 5,257 km, the rear rim problem occurred again and was replaced. (28.06.2024)

The same problem occurred again less than 2 weeks after the second change. I reported the situation to the service and was told that the rim change could be done for the third time under warranty.

I continue to be aggrieved due to the problems caused by the rim of the engine I purchased, which was completely manufactured incorrectly by the company. It is obvious that the product is defective. I do not want to be aggrieved and upset about the issue any further. I am waiting for your support regarding the replacement of my engine with a new one."

Re: Primavera knackt unregelmäßig am Hinterrad

Tja!
Leider ist das Klackern am Hinterrad meiner PV125 jetzt wieder einige Male aufgetreten, nachdem es monatelang (ich dachte eigentlich für immer) nicht aufgetreten ist.
Allerdings nur wenn die Außentemperaturen einigermaßen hoch waren, so ca. ab 20° Lufttemperatur.
Ich wollte es zuerst gar nicht glauben, aber es ist tatsächlich wieder da.
Letztes mal am 16.10. nach 25km Fahrt. Und da war es gefühlt sogar noch lauter als vor dem Tausch der Hinterradfelge.
Das gefällt mir überhaupt nicht.

Vor allen Dingen habe ich mir überlegt: Wenn ich jetzt die Felge noch mal auf eigene Kosten ersetzen lasse, dann habe ich wahrscheinlich am Anfang wieder Ruhe, aber vielleicht tritt das Problem ja dann nach einigen Monaten bzw. ein- bis zweitausend Kilometern wieder auf. Wer weiß das schon. Und solange Piaggio das Problem nicht analysiert hat, weiss man nicht, ob eventuell Spätfolgen außerhalb der Garantie auftreten.
Also jetzt bin ich schon ziemlich enttäuscht von diesem Hersteller.

Egal. Also heute dann beim freundlichen Vespa-Händler angerufen.

Den Vorschlag, einfach mal auf Verdacht die hinteren Bremsbeläge zu tauschen (würde mich um die 100 € kosten, weil keine Garantie auf Verschleißteil!) hatte ich zuerst in Betracht gezogen.
Ich fragte dann, was denn unternommen werden würde, wenn das Problem danach (Tausch der Bremsbeläge) doch wieder auftreten würde.
Sie würden den Roller dann an Piaggio Deutschland (mit Sitz in Düsseldorf) übergeben, hieß es von Seiten des Händlers. Für einen solchen Termin bestünde aber momentan eine Vorlaufzeit von 4-5 Monaten.

Daraufhin habe ich den Vorschlag mit dem Bremsbelagtausch verworfen, und direkt um eine Terminreservierung bei Piaggio gebeten. Allerdings unter Berücksichtigung der Tatsasche, dass sich das Problem bei niedrigen Temeperaturen kaum nachstellen läßt, es also wenig Sinn macht, den Roller im Januar/Februar an Piaggio Deutschland zur Untersuchung zu übergeben. (meiner Einschäztung nach wäre April oder Mai 2025 passender, Garantie ist ja noch bis Juli oder August)

Jetzt bin ich mal gespannt, was ich für eine Rückmeldung bekomme. "

Re: Primavera creaking noises irregularly at the rear wheel
#65 Post by Balrog » Tue Oct 22, 2024, 11:18 am

Well!
Unfortunately, the rattling noise on the rear wheel of my PV125 has occurred again a few times now, after not occurring for months (I actually thought forever).
However, it only happened when the outside temperature was reasonably high, around 20°C (68°F) or higher.
I didn't want to believe it at first, but it's actually back.
The last time was on October 16th, after a 25km ride. And it felt even louder than before I replaced the rear wheel rim.
I don't like that at all.

Above all, I thought: If I have the rim replaced again at my own expense, I'll probably have peace of mind at first, but maybe the problem will reappear after a few months or one to two thousand kilometers. Who knows? And until Piaggio analyzes the problem, it's unknown whether there might be any long-term consequences outside of the warranty.
So now I'm pretty disappointed with this manufacturer.

Anyway. So today I called the friendly Vespa dealer.

I initially considered the suggestion of replacing the rear brake pads just in case (it would cost me around €100, because there's no warranty on wear parts!).
I then asked what would be done if the problem recurred after replacing the brake pads.
The dealer said they would then hand the scooter over to Piaggio Germany (based in Düsseldorf). However, there's currently a lead time of 4-5 months for such an appointment.

I then rejected the suggestion of replacing the brake pads and asked Piaggio directly to book an appointment. However, considering the fact that the problem is difficult to reproduce at low temperatures, it makes little sense to take the scooter to Piaggio Germany for inspection in January/February. (In my estimation, April or May 2025 would be more appropriate, since the warranty is still valid until July or August.)

Now I'm curious to see what kind of response I get.

Thank you for reply again.

Please excuse me, you are right. User "Balrog" has actually reported that the error has returned on his Vespa. I had overlooked that!

However, I would like to point out that this user reported multiple problems with his vehicle and his dealer.

For all other users, the fault was rectified after replacing the rim.

If there were problems with one batch of rims, it is conceivable that the replacement rim came from the same batch. In this case, it will have to be replaced again. What else is there to do to solve the problem? Once again: Replace the rear rim/tires with another Primavera/Sprint and report whether the fault migrates. Then the cause is clear.

Yes. You are right, some users said that there was no sound after changing the rims. I was just wondering why there was still noise after changing them again. Maybe it is due to one batch of rims as you said. Thanks for your answers...

The sound comes from the splines not matching up 100%.
I had it happen on my 2022 & 2023 Primaveras.
Warranty paid to replace the wheel/rim. Sound stopped.
About 1500 miles later, it came back.
My mechanic wants to put some type of grease or paste on it now
to test it again. I don't know what it is made of, but he said it
would have to sit overnight. I just decided to live with it.
I only hear it when the motor is off and I'm backing up the scooter
into the garage. Otherwise, it's non-existent.
I'm now wondering if a slight filing of the edge of the splines would
eliminate it. But I'm not worrying about it enough to do something
about it any more.

u talked about these splines? and splines are at the rims? its not hearing at stand when i rotate the wheel. But when engine is hot, its hearing. by the way thanks for answer.

According to my mechanic, it was the matching set on the wheel. And yes, it only happens once you have ridden a few miles. I do not know why, but I'm assuming that after a short ride, they heat up and expand.
After sitting over night, they don't click the next morning until after a short ride.

When the bike was placed on a lift, there was no clicking that I could hear when turning the wheel by hand. But my mechanic turned it very slow, then called me back into the shop. The sound was very light, like sliding a piece of plastic off the edge of another piece of plastic onto the floor, a very light plop.

All this is just what happened to me twice and doesn't mean it is the same thing for you. But from your description I'm still thinking it is.

Ok thank you. I think there are several solutions to this. Because someone wrote that it is related to bearings. Thanks for your answer.

I've been following this thread and one on German forum since last year. Our first Vespa (2023, bought in 2024) developed this clacking sound at around 500-600 kms. Now 2100 kms, it rides as it should just keeps clicking (only when hot, under the weight or without and not on the stand).
When I went for the first service we had a chat with the service manager, he said they've changed someone's rear wheel (they still had the old wheel there, non of us could see anything wrong with it).
Our other Vespa which we bought a month and a half ago (now 900 kms) doesn't make any sound (yet).
I don't know what to do now. Change the wheel or not?
As nobody up to now didn't report any problems due to this issue I think might just ride it and as it was reported and anything goes wrong they'll have to deal with it even after the warranty expires. Hopefully till then the real cause will be known.

If you look at the last posts in the German forum, you'll see that one user ("obra") has tested or replaced pretty much all the bearings and surrounding parts. In the end, he returned to the original solution: replace the rim. He describes a difference between the rims up to MY23 and from MY24 (facelift).

If the rear wheels are interchangeable between your two scooters, then try swapping them over. If the sound follows the wheel, you have the culprit - if the sound doesn't re-appear then all is good. If the sound stays with the first scooter then you have to find something else...

at German forum "obra" changed the rims with 2024 ones and says no clikcing sound more. i also bought rear rim and waiting for to delivery. This is what i buy i attach the photos. I hope it will solve the problem.
