Modern Vespa

Hi,
2 months ago I bought a Vespa GTV 250 from 2008.

The motorcycle had been stopped for some time and had not been maintained.

The motorcycle has 45,000 km ( 27000 miles)

Apparently the exterior and the sheet metal are very good.
It is preserved in good condition

Once in my garage I changed the oil engine (Motul), oil filter, Malossi red air filter, hub cube oil, variator filter, circuit cleaning and new coolant, new brake liquid ( dot4), new tires ( were hard and glassy) , new burned out bulbs...change old fuel...

It had a motor error fault and have high voltage peaks in the battery that were solved by replacing the voltage regulator.

I did a basic maintenance because i dont know previous maintenance history.

The bike starts and runs.
It has a strange sound, mentioned in another post, which may be from the transmission. No bright lights on dashboard .

Strange Noise Vespa GTV250 (2008)

On a flat surface max speed is about 110 km/h (68 mph), on a Hill the máximum speed is about 100 km/h( 62 mph). My weight is 90 KGS

I think it is low speed for a vespa gtv 250. My old vespa p200 2 T (1980) does those speeds.

What do I need to do to have more maximum speed?

Chage belt transmisión?
Which belt ?
Vespa original?malossi, others ?

Change variator and rollers? Original? Malossi multivar 2000? Polini 9 rollers?

Cluntch need something??

Its necesary update ecu software?

What would you do to increase speed?

Thanks for all!!

That is pretty much it for the 250.

Change belt transmisión/Which belt?

Vespa original is

Change variator and rollers? Original? Malossi multivar 2000? Polini 9 rollers?

Original is fine, if you go aftermarket you have to play around getting roller weights right.

Cluntch need something??

Not unless its worn.

Its necesary update ecu software?

No, if you want that much power sell ot and get a GTS 300 supertec

What would you do to increase speed?
Not alot on one of these.

not all 250's run 70+ MPH. really depends on how it was first broke in and rode those first 1000 miles.

ride it for what it is and enjoy.

I'd previously assumed newer vehicles were quicker, but newer vehicles are heavier and have much stricter emissions testing now.

My modern 125cc is much slower than a lot of old classic Vespa's that have a similar cc.

Aftermarket variators will either improve acceleration, top speed or both. As you've been doing this work yourself, you should be able to easily change the variator - and it will be a cheap upgrade.

Both Malossi and Polini are highly rated companies - so either will be good. See what prices you find.

The idea is to do it myself.

I have had classic Vespas for over 20 years and In my area there are few classic Vespa mechanics and over time you learn to do your own repairs although the world of automatic Vespas is new to me.

You can't simply compare cc between a two stroke and a four stroke. 🤦‍♂️

The OP is asking if something is wrong because his modern 4 stroke is feeling slower than his classic 2 stroke.

The 2 stroke is very likely the quicker of the two…

I know they're different engines, but my initial flawed thought was "old engines must be slower", regardless of engine config. I'd assumed 50 years worth of development would have meant the new engines being produced today were leaps ahead, when it's still behind.

The variator is probably fine, but the rollers may be worn enough to give you faster acceleration but slower top speed. You can replace the rollers fairly easily. I generally use the factory standard size in my scooters because I like them the way they were made, but that's up to you. The belt may also be worn. Even if it looks fine, try and measure how wide it is across its outside surface - the back. I don't recall the correct width, but if it's narrower by much it's worn, which will make you have slower top speeds.

Also, make sure your tire pressures are correct or even a bit over factory recommendation - you are a pretty big person and under-inflated tires will slow you down.
