I guess at the end I will spend a bit more.

But for a Vespa Sprint S 50 2t.

so, a little update then,mine i exactly like yourse now, about 50-55 and close to 60 downhill but it still accelerates painfull slow but i guess thats life with 4T i think im going to sell it or try the 125CC ecu box on it, they diddent whant to to that for me..

Did they change the final drive? Is it on lower rpm now?

I know what is the problem. But how did they fix it? Is the final drive ratio interchangeable?

Please some info if anyone has an idea.

Is this gearbox a problem in the Agility R16+ 50 2t TWO STROKE? The new one is with 14 inch wheels. I wonder if it can go 70kph.

4T with the fuel injection.

Ah, thank god. This is about the Agility 16+ carburetted 50 2T. Not the slow injection one.

I would never consider anything that slow for myself or my family - spesially for safety reasons.
Right or wrong, I beleive that by riding slower than other vehicles on the road, changes are better to be getting knocked of by other vehicles on the road.
Personally I would never consider anything smaller than 125cc.

Depends on local laws. If 50 is the limit, than that is the limit. (70-90cc with kit)

But all 50cc are not the same. That is why I am looking for help.
The iget50 gets 10-45kmh in 7 seconds
Kymco People S 50 4t gets 10-45kmh in 9 seconds
The SR50 gets 10-45kmh in 5 seconds
Kymco People S 72cc 2t gets 10-45kmh in 4 seconds

Those are all registered as 50cc, but are not the same at all. The honda PCX 125 gets from 10-45kmh in 3 seconds.

OK, certainly seems as though you will not be another frustrated 50 owner!
Please share a photo of the Kymco you decide on.

I hope not and off course I will.

I'm thinking you are in Great Britain/Europe?  In my understanding of the laws there, insurance and licensing laws are much different and and more expensive than here in the US.  Is it not also illegal to modify your scooter? - So don't get caught as I understand.

That said, looking at Kymco vs the many China brands is a good choice.

I was not aware that you could get a 2T 50cc still.  It has been a few years since they have been available here.  The Kymco 2 strokes are a good engine for modifying, and do not require a crank replacement as some other mfgr's do.  A pipe, cylinder kit, and carb can get you 60 mph and still be a daily driver - although you probably will not be happy with the fuel consumption. 

I recall an issue with late model 50cc in that the CDI needs to be replaced in order to take advantage of the hot rod parts if you go that way - I don't remember if you need a AC or DC.  You may still find some European based scooter tuning site with info on that.

Also, you have fewer brand choices for Kymco hot rod parts.  SIP in Germany is your friend. 

My Super 9 has no problem keeping up with city traffic - yet due to licensing it is illegal to go over 30 mph...(I don't worry about getting caught - figure police have more important things to deal with). It has no problem keeping up with 125cc scooters.  Scooter tuning is fun, but time consuming and expensive.

Can't advise you about the 4T's and hot rodding - the big bore kits will make a difference, though.   The stock 50cc 4T's are dreadfully slow - I always cringe when someone shows up with one on a club ride - means we will be waiting on the slow poke often.

As many of us have found, a 125/150 class scoot is much more practical.

Good luck with your choice!

Yes, I am from Europe. The laws are very different, but the distances travelled are also a lot different. You can change almost anything on the scooter, tuning is not illegal or a problem. As long as the chassis number and plates correspond. One of the last 2t is the Kymco Agility 16+. Here is the SR50, and some Chinese bikes. The choice is narrowed down.

I have Malossi parts here, and Motoforce or something similar. I plan on using Malossi somewhere down the line https://www.malossistore.co.uk/kymco-agility-r16-50-2t-euro-2-kf10b-kyag50162-M
My plan is:
1. Is to check out the exhaust and derestrict washers if there are any. That should free up a lot of power on its own. According to the graph that I posted above. 3.25HP, to 6HP improvement.
2. Is to check the boss if it is limited. If it is then replace it with unrestricted. This might slow down the acceleration but improve the usage of the variator.
3. Is to put Dr. Pulley sliders to improve the lost performance from the boss, and gain acceleration. Also target is at least 65kmh/40mph top speed.
4. Is to check the mixture and swap a carburettor jet #82 if it seems lean.

This should in theory provide the performance that should a 50cc scooter have. And this is considered stock in my book. Because it is as the scooter should have exited the factory.
After a while:
5. perhaps I will put a Malossi 47mm piston and cylinder. If I am bored for example.
6. And perhaps put some a bit heavier sliders to quieten down the engine, and keep the consumption in check.
7. I want to put some Metzeler Wintec, sticky winter tires so I can gain stability in the rain, and oil spills.
8. A LED headlight to make it look more 2019, and less 2006.

And that should be about it.

The law dictates and makes the 125cc logical. In some countries you can drive 50cc with no license. In some countries that limit is 125cc. In mine it is 50cc. It sucks a lot, but that is the reality. A 125 here makes absolutely no sense to me. If I am passing the tests and getting licensed a 250cc seems the minimum that I would get. Why limit myself to 125... 125 are the least sold motorcycles. We have 60% of the motorcycles under 50cc, and only a 2-5% are 50-150cc, the rest are all above 150cc. Because the law dictates the 50cc limit. If it was 125cc with no license, or only with tests - with a learners plates like in some nice countries, then I assure you 90% of bikes would be 125cc.

P.S. Any suggestions or criticism are welcomed!

I am considering a 50cc family scooter. Family in the sence that anyone can drive it legally with no special license. Thus the 50cc limit.

Initially cheap scooter is the choice because of peace of mind in terms of stealing, and vandalism.

That said I live in a relatively flat city with 5km distances that need to be covered. A 50cc scooter needs only 1 registration and then nothing. It is pure utility and no wasted cache. 10euro/dollars per year insurance and that is it.


In the shops the Chinese brands are not a safe buy for me. I would like a reliable bike. Hense looking at Kymco. We are rather tall people 190+cm/6'2"inch, and a larger scooter is a must.

My choices are:

The Kymco Agility 16+ 50cc 2t Euro2 for around 1900euro/dollar
www.kymco.com.cy/en/kymco-scooters/kymco-50cc-scooters/98-agility-16-50-2t

And the Kymco Like 50 4t euro4 for arround 1700euro/dollar.
www.moto.it/listino/kymco/like-50/like-50-4t-2009-18/9Ku17x

I have ridden Kawasaki 650, Yamaha fzr and similar.

I can't try these scooters to find out if they are fast enough for normal driving. Whichever I get I plan on derestricting immediately to get normal and safe performance on the road. After a year or so an upgrade kit would be put for a larger bore.

My questions,
1. are the Kymcos mentioned easy to derestrict?
2. Is the Kymco Like 50cc 4t unsafely slow?
3. Can the Agility 16+ 50cc 2t be made reliably 72cc?
4. Is a 72cc 2t faster than 90cc 4t?
5. What would you choose in my place and why?

Any manuals or tutorials for derestricting new kymcos?


P.S.
Liability insurance is mandatory. And a good thing! No other expenses for 50cc.

That is why a 90 4t or 72 2t registered as 50cc is a very good option, if it can travel at 60kmh reliably, and 60kmh on small hills.

P.P.S.
I am not looking to get a used scooter, they hold too much value in my country, and after 10 years it will be 50% of the price. Especially for a 2t which god knows how it was lubricated.

Kymco has a very good servicing and parts availability at my country. All deliveries use them, all parking validators use them. And generally the consensus is that they are very reliable. And on top of that a lot of aftermarket parts are available for them.

The Agility 16. But it is the new version from Agility City. And uses the same 2t as all Kymcos. The Like is also the 50cc 4t that is used in all Kymco models.

My only concern is that the 4t is euro 4, and can be upgraded. But will I be able to transport myself on a 50cc 4t for a year? Or will it be dreadfully slow, especially on a hill. I have seen this video:

My opinion is that this is horrible performance. 32kmh/20mph uphill seems deadly on a public road! But will it be that slow when derestricted? Euro 4 means the cleanest possible scooter, 2t euro 2 bans are starting to appear in some EU cities.

That is why I am torn between the choices. Should I manage somehow not to die on a 4t for a while until the upgrade, or go for a 2t and risk a ban, but have normal performance for a year, and upgrade then to excellent performance.
