Modern Vespa

Can someone please give me the top speeds of all or most models.Thanks!

Ludicrous!
Welcome to MV.

They can all go fast enough to get speeding ticket.

In seriousness though, there are nearly too many models to list. Can you narrow it down?

Vespa does not publish the top speed anywhere in its technical data.

The only (reliable) source I know for the top speed (for all current models) is
https://www.fulland-vespa-store.de/motorroller
-> look there in the respective vehicle -> tab "Technische Daten" (= "technical data") -> "Höchstgeschwindigkeit" (= "topspeed") in kph

Please note that all 50cc-Versions in the European markets are limited to 45kph due to law/driverslicense restrictions, which is 27,96mph. For the non-European markets I have seen everything between 27-30mph, so double-check.

If you need in addition the topspeed info for specific older Versions (i.e. Euro 3/4, GTS pre-Facelift, etc.) please let me know.

I was into jet ski's during the 1990's. There was a jet ski magazine that provided radar runs of all models. They showed great graphs of the runs.
I tried to figure out a low cost radar with graphing software so I could do something similar. The price of radar guns was too much.

A distinction must be made between a factory specification for the maximum speed and the speed that can be achieved under real conditions.
The factory specification is certainly determined on a chassis dynamometer. Under real conditions, many factors play a role: temperature, wind, gradient, (rider) weight, rider size, clothing, windshield yes/no, series dispersion, how measured (speedo, gps), etc.

This discussion can really be simplified. If you want to go on the Freeway/Expressway Autobahn (what ever you call it) The Vespa 200-300 is your pick. The 150cc and below are best suited for urban side streets.

I know that folks here have long range toured on 150cc and below Vespas, but, the machine for all purposes that has get up and go is the Vespa 300.

I am not a fan of blasting down the road at high speed. I like to take in the scenery and smell the roses. Thus, I am a scooter guy. Although, I do acknowledge some of you have a need for speed. If you really want to zoom, get a motorcycle.

A 2010 GTS 300 has a top speed of 84mph according to my GPS. That's on the flat, no wind, full 'tuck' behind an OEM flyscreen

All Piaggio models? The GP800 could get up to 130mph...

Are you trying to choose a Vespa? Win an argument about fastest scooter with a friend? Or?

As well as position in your local gravity well: https://archive.scooterlab.uk/red-bull-vespa-freefall-from-4000-feet-feature/
"Sitting on his Vespa, he raced towards the earth at over 300 km/h."

I heard as general rule of thumb. The 50CC do top speed of 40MPH, the 150CC do a top speed of 60MPH and the 300CC do a top speed of 80MPH. Again, this an approximate and general speed not exact.

Can simply put on a large diameter wheel+tire to get a bit more top speed

So, guessing the OP got his answer?

Just take whatever anyone says their Vespa can do based on it's speedometer, and subtract 10% and you'll be pretty close to it's actual speed. Amazingly, it works equally well for KPH or MPH.

Oh, I took your advice, Bob, but my mood (obviously) varies widely, so I'm keeping the GTS too...

2010 Honda SH150i. (all MPH) 65 without windshield 70 with.
2014-2015 Piaggio BV350 86 shield or not. Sorry no Vespa.
I get faster results by Googling make model top speed.
OP?
OP?

I own a VESPA GTS300. I notice topping out around 80.....

On my 2007 GTS 250, I hit 84 mph per my GPS on I-75 just north of Cincinnati.

Dry and coolish April day on a long flat stretch of highway, little or no cross-winds.

The reality is the 200 GT and up are capable of highway speeds, but that is not where they are best suited. Riding down an isolated twisty 2 lane road at 50-60 mph is where you'll get the best of these scoots.

My guess based on it being a new account with one post?

Scrap data for an article for a site that churns out massive amounts of content without any actual experts doing the writing.

This is how they do it. They show up, ask the experts, "Can someone please give me the X of Y." and then publish an article titled "The X of Y" (or in this case top speeds of all Vespa models, fastest vespa models, blah blah blah).

And then when actual experts and enthusiasts try to produce their own content, well, it's swallowed up by all of the much bigger publishers that have no actual expertise or passion for the subject.

You could make an article on Vespe, after decades of riding one across all that crazy Australian landscape, and get outranked by an inferior article written by someone who's never even sat one, in a country where Vespa might not even be sold, because it's a generic mass publisher putting out the content.

I'm not participating in this one, not at all...

I think this is a fairly good general rule.
Except for the 50cc in markets where 50cc's are limited in speed to some 28mph.

My BV 300 ie will probably do that 130kph (80mph) and I can easily follow traffic going at 120kph on the motorway, but that is not very pleasing to me, and I think also not very pleasant for the engine.

The best speed for the BV in my view is in the range of 70 - 100kph (45 - 60mph). Then it is running effortlessly and humming like a sewing machine.

I just made the Kessel Run in twelve parsecs!

Is that the speedometer reading, or GPS?

If speedometer, arbitrarily deduct 8-10%.

My experience is that GPS is not necessarily always 'nuts on', but will almost always be within two MPH of actual speed, or probably no more than one mph off at highway speeds.

At anything much over 55 mph, I just mentally dump 5 to be 'sorta close' to what I'm actually moving at, and even that might still be a little optimistic.

On level road with still air, I highly doubt that the GTS300 HPE is capable of ever achieving an actual 80 mph.

I have seen 85 on my GTS's speedometer, but I was on a long downhill section, and was ringing it's neck to see that number.

When people ask me how fast my Vespa will go, which is quite often, I feel that I'm being reasonably honest when telling them that it should be able to hit 75 under favorable conditions. They're almost always quite surprised and impressed by that number, apparently thinking that any step-through scooter, or 'moped', can't exceed 40.

speed limiter in my hpe (pre-2023) is 130kph speedo = 81mph which is approx 120kph gps = 75mph (but gps is unreliable as I've tried to discuss elsewhere which upsets people as they don't want to hear it). You can bounce against the limiter and go a tiny bit above this especially with tailwind or downhill or drafting behind a truck etc.

for the 2023 my understanding is it's lifted by 10kph. (some have suggested limit removed but other testing I've read said its 10 which sounds more likely to me as there is still the rpm limiter ...)

there are other ways to go faster such as tone wheel, 13" wheels, forcemaster, etc

I had the tone ring, but decided that it wasn't worth the trouble to install, so gave it to another member here.

I have used two GPS's against my GTS's speedometer, one is off by 2 mph at about 65 indicated, and the other is 1-1.5 off at that speed, both reading lower than indicated. I understand that curvy roads can upset the GPS readings according to some, and I have no reason to doubt that, but it's a minor issue in the wide view.

One thing that can be said about the Vespa GTS300's speedometer is that it is indeed consistent...consistently inaccurate.

I question how much more speed the 24 hp HPE 278cc engine is capable of, if any, over what it can in do stock form. The bike just doesn't have a lot to work with in that regard, and effectively gearing it 'taller' with larger diameter wheels would, as an inevitable side effect, slow acceleration to some degree wouldn't it?

What happens to the engine revs with a 10 kph increase in road speed?

I don't take all this top-speed and speedometer accuracy stuff nearly as seriously as I might make it sound in my posts here, it's just some conversation for the sake of conversation. My built in seat-of-the-pants-speedometer is always right on, and when I sense that I'm moving at a satisfactory speed, I'm content, regardless of the hard numbers the bike is showing me.

My stock GTS300 84mph was measured on a GPS - it kept it up for bang on 99 miles, when the just-filled tank ran out. The speedo read way over 90. Cannonball 2012.

My GTS250 back in the UK would do just over 80mph. <<< Yes, GPS verified.

Yeah, my pre-HPE also went faster than my HPE. But it also accelerated slower. I prefer acceleration.

Not really... the top speed is usually aerodynamic drag limited. When that is the case, going to taller gearing (which is what a larger wheel/tire diameter actually is) will accomplish nothing unless you can come up with a corresponding increase in horsepower (and it will decrease your acceleration rates).

Yes and no.

If the existing limit is horsepower then you're right. But if the existing limit is an artificial limit in the ecu that monitors the wheel speed (and rpm) then a larger diameter will give more top speed. In the HPE it is an artificial limit in the ecu and it is easy to reach this artificial limit.

yup 130speedo/120gps on pre-2023 is typically hit around 8700-8800 rpm. the pre-2023 rpm limit is 9000. (ecu will slow you a tiny bit when you hit either the rpm or wheel speed limits)

for the the 2023 to reach +10kph it must have lifted the rpm limit from 9000 to 9500.

I been riding a Vespa LX50 in Florida only on backroads for 10 years. I wanted to get a Vespa in PA. I know I needed to go to either the 150 or 300. I got the 2023 Vespa GTS300 Supertech so I have the GPS (I have no sense of direction) and needed Turn by Turn. I was so surprised at the acceleration and top speed I love it and can go anywhere with it in the Hills of PA. I programmed the GPS to always avoid highways and so fun to see the roads it takes me on. I have always been a Vespa owner never a Motorcycle so likely they may not get the same thrill I get from riding it. Now I have to trade in one of my 2 LX50's for a another 300 SuperTech in Florida so I can go everywhere on that too. I need to get that extra light below the top box since Florida drivers worry me more than PA drives.

I'm still taking this in. But so far it say that ancient Lambrettas have better aerodynamics and/or Vespas are intentional low geared and run out of revs.
I'm still absorbing.

Back around 1960 the joy of my Vespa GS150 was that I could overtake the 150 Lambrettas in 3rd gear and then as I pulled ahead I would change down to 4th gear just to rub it in.

Please don't tell me you also liked the Beatles.
