How fast does a Piaggio Zip C25 run?

Hey,

I'm relatively inexperienced when it comes to screwing and scooters. But I know the basics…

Yesterday, I bought a used 50cc scooter (model in the title) through the classifieds. The seller stated in the title that it was a 2-stroke. Is that true? Is it stated on the paperwork? If so, where?

I wanted a scooter for spring, summer, and possibly fall that I could ride all the time, and it should be problem-free. So, I wanted something reliable rather than a project that required some work!

They said everything was great, nothing had ever been done to it, everything was original. That was pretty believable. I test drove it, and everything worked perfectly. After using the electric starter for the first time, it started right away! The seller's dad just drove the scooter the whole time and now he doesn't use it anymore.

I then briefly drove up and down the street since it wasn't registered. But with the throttle fully turned down, I only managed about 22 km/h. It didn't pull very well either :/

The owner said it had been sitting for a while and the engine was cold. Is that true? I can imagine it, but I'd need an expert opinion 🙂

So my question: Has anyone had any experience with how fast these things go? The speed rating says 45 km/h, but I'm hoping it's around 50. As I said, everything on it is original; nothing has been changed. Only new original parts have been replaced.

Could there perhaps be a throttle ring installed that only allows 45 km/h?

Thanks in advance, sorry for the delay

Kind regards

Your scooter is a two-stroke scooter that is throttled to 25km/h when it is in the original state – so the speed you specify is realistic.

It will become a bit faster when it runs regularly and the engine is warm.

He’s throttled so he can be driven from 15 years.

The roller is throttled at at at least five different points to make it difficult to unthrottle.

If you had taken a c 50, he would not have been throttled and he would also reach the 50km/h you were feeding.

I can’t judge if you were entitled to drive a scooter at a higher speed.

If you were only allowed to drive 25 km/h, but then you would get rid of your scooter and drive with it, then you would be punishable.

If you want to unthrottle your scooter, then parts would have to be exchanged at three places and various rework would be done.

By:

The manufacturer does not distinguish between models C25 and C50 without reason.

The difference is that the C50 is open and the C25 is throttled.

I can’t judge from the distance whether you’ve been unthinking your C25, and I could see it on site.

The fact that you haven’t reached 25km/h during the test drive suggests that it is really a C25 in the throttled original state.

In fact, the C25 is NOT throttled via a throttle coil, but rather via the position of the inlet channels in the cylinder, the intake manifold (diameter), the gasifier (diameter), through a spacer disc and other rollers in the Variomatic and through another resonance tube in the exhaust.

An unthrottling would thus be associated with much more work than the removal of a coil.

Why you were told that you were driving 45km/h, but I can’t say.

If you were to measure the passage from the carburetor (internal diameter) and that would be 10 mm, the scooter would be at least there in the original state, i.e. throttled.

If you would open the Variomatic and see a spacer there, the scooter would be throttled.

If you were to weigh the reels in the Variomatic, you would know if the scooter was throttled.

If you were to measure the diameter and length of the resonance tube in the exhaust, you would know whether the roller is throttled,

If you were to measure the inside diameter of the intake manifold, you would know if the scooter was throttled.

All points I can’t judge from here.

And why do you ask (see the first version of your question I answered) about a ZWEITAKTER and this at the same time in another forum?

What are you writing?

You only post the photo of your papers to my request, but you only wrote it by a ZWEITAKTER.

I’m on my way and can only write about my phone, but I’m looking for…

Yes, according to your question – please read it – it is a two-strokeer.

In at least one other forum you wrote that.

Please don’t tell me now that it’s a four-clocker and, if so, then.please change your question before others use considerable time to search for reasons with a two-clocker.

As I said, remotely, I helped you as far as I could.

I have to rely on what you write but on my data sheets.

It may be that your scooter is open – not everywhere apply the provisions relating to Speed, as in Germany.

The points where you can see if it’s throttled, I called you.

That’s all I can do for you.

I don’t know your skills, I don’t know what you have on tool, but knowing which carburetor is installed, or what hole it has, would be interesting.

Otherwise you’d have to go again and see how fast he is.

Can you return the part?

Probably not.

Then you can try for an ABE first or have to call if you really gave you everything.

Often you put the ABE together with the insurance cover and the folder is still flying around with the seller somewhere.

And now it's good…

Where did you get the ABE?

Is that all you got to the scooter?

Please look here:

Have a thought:

If I have a car and that’s a couple of weeks, and I’ll drive with it… then that’s only half the top speed….

Just post your vehicle license in your question.(possibly pers. make information unrecognizable)

Then everyone has something to read about here.

As far as the cost of dethrotating is concerned, I cannot give you any information because I have no workshop….

Intake manifolds, gasifiers and exhausts would have to be new.

In the Variomatic, the spacer would have to be removed and the rollers could be left if necessary.

In order to “optimize” the position of the inlet channels in the cylinder, two, three additional cylinder base seals could be installed, then no new cylinder would be needed.

I’ll give you a link.

Perhaps interesting because the difference between C25 and C50 is explained.
